Battle lines being drawn over online freedoms in Asia Expert comment NCapeling 22 March 2021

Social media giants are increasingly clashing with Asian governments over free expression and censorship as the region lurches towards digital authoritarianism.

Freedom of expression was subject to significant restrictions in Asia even before the pandemic, with several governments having enacted laws that stifle online debate. But since COVID-19, restrictions have increased even further due to a rash of so-called ‘emergency measures’ introduced by governments across the region.

Bangladesh, India, Indonesia, Malaysia, Myanmar, Nepal, Pakistan, the Philippines, Sri Lanka, Thailand, and Vietnam have all put new laws into place, and many restrictions are already being applied in a draconian fashion, such as in the Philippines and Bangladesh.

As outlined in a new Chatham House research paper, one inspiration behind this trend is China, home to the world’s most sophisticated and restrictive system of internet control. The Chinese government’s restrictive online regime, which has tightened further under COVID-19, relies on a combination of legal regulations, technical controls, and proactive manipulation of online debates.

This model was an inspiration for Vietnam’s cybersecurity law, as well as Myanmar’s new draft cybersecurity bill, proposed by the Military-run State Administration Council in the wake of the military coup last month, which would give the military there extensive powers to access individuals’ data, restrict, or suspend access to the internet.

This ‘sovereignty and control’ model of internet governance is also gaining impetus through China’s ‘Digital Silk Road’ initiative, under which the Chinese government is exporting both its technology – such as through the establishment of smart cities, the installation of AI, and surveillance technology – and its vision of how the internet should be governed.

In November 2020, Xi Jinping pledged to further deepen cooperation with ASEAN through the Digital Silk Road, and the pandemic has expanded the appeal of Chinese surveillance technologies and data collection platforms to governments both in Asia and beyond. China’s Health Silk Road, which aims to promote global health cooperation, is centered on the Chinese government’s high-tech model under which civic freedoms are sacrificed in the name of public health.

An alternative model

This ‘sovereignty and control’ model is increasingly at odds with the more ‘human-centric’ model of tech governance favoured by many democratic states, Western social media companies, and international institutions, especially the United Nations (UN) and European Union (EU).

Although this emerging model also involves regulation, it is regulation which aims to be inclusive, risk-based, and proportionate – balancing the need for protection against online harms with the need to preserve freedom of expression. It is a multi-stakeholder, rights-based approach which brings together not just governments but also representatives of the private sector, civil society, and academia. The EU’s draft Digital Services Act and the UK’s proposals for an Online Safety Bill are both reflective of this approach.

Western social media giants such as Facebook and Twitter have recently introduced new policies which seek to identify and mitigate online harms, such as hate speech and disinformation. Industry bodies such as the Global Network Initiative, independent oversight bodies such as the Oversight Board established by Facebook, and civil society advocacy and initiatives such as the Santa Clara Principles on Transparency and Accountability in Content Moderation are also an important part of the picture.

Admittedly, these various digital governance initiatives are in some cases embryonic, and are by no means a silver bullet solution to the complex problem of online content moderation, which continues to be hotly debated in democratic societies. But they are at least underpinned by the same philosophy – that international human rights law standards must continue to apply even during emergencies such as COVID-19. With the Biden administration in the US prioritizing tech governance in its policy agenda, there is added momentum to the international leadership behind this model.

A clash of ideology

These conflicting philosophies are playing out in debates on technology governance at the UN, with one group of countries led by China and Russia advocating for greater government control of the internet, and many Western democracies emphasizing the need for an open, global internet that protects human rights.

These differing ideologies are also creating tensions between Western social media companies operating in Asia and the various governments in that region which have increased restrictions on online expression. And the gulf between the two appears to be widening.

In 2017, the Thailand government threatened Facebook with legal action unless it agreed to remove content critical of Thailand’s royal family and, in 2020, Facebook announced it had been ‘forced to block’ such material. Also in 2020, the Vietnam government pressured state-owned telecom companies to throttle internet traffic to Facebook, effectively restricting access to the platform, until Facebook agreed to take down content the government deemed to be anti-state.

Platforms refuse to silence legitimate criticism

However, Silicon Valley’s social media companies have also been pushing back. Facebook restricted the accounts of Myanmar’s military on the basis of ‘spreading misinformation’ in the wake of the military’s imposition of an internet shutdown that blocked access to Facebook, Twitter, and Instagram. And Twitter resisted requests by the Indian government to block accounts involved in protests by farmers.

Twitter stated that while it would block any accounts which it felt incited violence, it would not take action on accounts belonging to news media entities, journalists, activists, and politicians because it believed that would ‘violate the fundamental right to free expression under the Indian law’. The Indian government responded by fast-tracking stringent new social media regulations heavily criticized by rights groups for increasing government power over content on social media platforms, including online news.

So how can social media companies find avenues for operating in Asia and beyond without being co-opted into the lurch towards digital authoritarianism? There are no easy answers here, but collaboration is key. Cooperation between tech companies and local civil society partners can help companies better understand risks to human rights in the country concerned and how they might be mitigated. And tech companies are more effective in alliance with each other than acting on their own, such as the refusal by Facebook, Google, Telegram, and Twitter to hand over data on protestors to the Hong Kong police.

The fact that in many countries in Asia there are no alternatives to Western social media companies – unlike China, where platforms such as WeChat are part of the government’s internet control apparatus – gives the companies concerned some leverage. In February 2020, Facebook, Google, and Twitter together – through the Asia Internet Coalition – threatened to leave Pakistan in response to the government’s draconian proposals to regulate social media. Along with pressure and lawsuits from civil society, this forced the government into retreat, although the tussle over the new rules, introduced in November, continues.

At a time when illiberalism was already on the rise in Asia (including in democracies – Freedom House has just downgraded India’s status from ‘free’ to ‘partly free’), COVID-19 has made tighter state control of online freedom of expression even more attractive to many governments. As it seems increasingly unlikely that restrictions enacted under the guise of pandemic-related emergency measures will be repealed once the COVID-19 crisis ends, it is even more important that tech companies work with civil society on the ground to minimize the censorship of citizen voices.

Can global technology governance anticipate the future? Expert comment NCapeling 27 April 2021

Trying to govern disruption is perilous as complex technology is increasingly embedded in societies and omnipresent in economic, social, and political activity.

Technology governance is beset by the challenges of how regulation can keep pace with rapid digital transformation, how governments can regulate in a context of deep knowledge asymmetry, and how policymakers can address the transnational nature of technology.

Keeping pace with, much less understanding, the implications of digital platforms and artificial intelligence for societies is increasingly challenging as technology becomes more sophisticated and yet more ubiquitous.

To overcome these obstacles, there is an urgent need to move towards a more anticipatory and inclusive model of technology governance. There are some signs of this in recent proposals by the European Union (EU) and the UK on the regulation of online harms.

Regulation failing to keep up

The speed of the digital revolution, further accelerated by the pandemic, has largely outstripped policymakers’ ability to provide appropriate frameworks to regulate and direct technology transformations.

Governments around the world face a ‘pacing problem’, a phenomenon described by Gary Marchant in 2011 as ‘the growing gap between the pace of science and technology and the lagging responsiveness of legal and ethical oversight that society relies on to govern emerging technologies’.

This ever-growing rift, Marchant argues, has been exacerbated by the increasing public appetite for and adoption of new technologies, as well as political inertia. As a result, legislation on emerging technologies risks being ineffective or out-of-date by the time it is implemented.

Effective regulation requires a thorough understanding of both the underlying technology design, processes and business model, and how current or new policy tools can be used to promote principles of good governance.

Artificial intelligence, for example, is penetrating all sectors of society and spanning multiple regulatory regimes without any regard for jurisdictional boundaries. As technology is increasingly developed and applied by the private sector rather than the state, officials often lack the technical expertise to adequately comprehend and act on emerging issues. This increases the risk of superficial regulation which fails to address the underlying structural causes of societal harms.

The significant lack of knowledge from those who aim to regulate compared to those who design, develop and market technology is prevalent in most technology-related domains, including powerful online platforms and providers such as Facebook, Twitter, Google and YouTube.

For example, the ability for governments and researchers to access the algorithms used in the business model of social media companies to promote online content – harmful or otherwise – remains opaque so, to a crucial extent, the regulator is operating in the dark.

The transnational nature of technology also poses additional problems for effective governance. Digital technologies intensify the gathering, harvesting, and transfer of data across borders, challenging administrative boundaries both domestically and internationally.

While there have been some efforts at the international level to coordinate approaches to the regulation of – for example – artificial intelligence (AI) and online content governance, more work is needed to promote global regulatory alignment, including on cross-border data flows and antitrust.

Reactive national legislative approaches are often based on targeted interventions in specific policy areas, and so risk failing to address the scale, complexity, and transnational nature of socio-technological challenges. Greater attention needs to be placed on how regulatory functions and policy tools should evolve to effectively govern technology, requiring a shift from a reactionary and rigid framework to a more anticipatory and adaptive model of governance.

Holistic and systemic versus mechanistic and linear

Some recent proposals for technology governance may offer potential solutions. The EU publication of a series of interlinked regulatory proposals – the Digital Services Act, Digital Markets Act and European Democracy Action Plan – integrates several novel and anticipatory features.

The EU package recognizes that the solutions to online harms such as disinformation, hate speech, and extremism lie in a holistic approach which draws on a range of disciplines, such as international human rights law, competition law, e-commerce, and behavioural science.

It consists of a combination of light touch regulation – such as codes of conduct – and hard law requirements such as transparency obligations. Codes of conduct provide flexibility as to how requirements are achieved by digital platforms, and can be updated and tweaked relatively easily enabling regulations to keep pace as technology evolves.

As with the EU Digital Services Act, the UK’s recent proposals for an online safety bill are innovative in adopting a ‘systems-based’ approach which broadly focuses on the procedures and policies of technology companies rather than the substance of online content.

This means the proposals can be adapted to different types of content, and differentiated according to the size and reach of the technology company concerned. This ‘co-regulatory’ model recognizes the evolving nature of digital ecosystems and the ongoing responsibilities of the companies concerned. The forthcoming UK draft legislation will also be complemented by a ‘Safety by Design’ framework, which is forward-looking in focusing on responsible product design.

By tackling the complexity and unpredictability of technology governance through holistic and systemic approaches rather than mechanistic and linear ones, the UK and EU proposals represent an important pivot from reactive to anticipatory digital governance.

Both sets of proposals were also the result of extensive multistakeholder engagement, including between policy officials and technology actors. This engagement broke down silos within the technical and policy/legal communities and helped bridge the knowledge gap between dominant technology companies and policymakers, facilitating a more agile, inclusive, and pragmatic regulatory approach.

Coherence rather than fragmentation

Anticipatory governance also recognizes the need for new coalitions to promote regulatory coherence rather than fragmentation at the international level. The EU has been pushing for greater transatlantic engagement on regulation of the digital space, and the UK – as chair of the G7 presidency in 2021 – aims to work with democratic allies to forge a coherent response to online harms.

Meanwhile the OECD’s AI Policy Observatory enables member states to share best practice on the regulation of AI, and an increasing number of states such as France, Norway, and the UK are using ‘regulatory sandboxes’ to test and build AI or personal data systems that meet privacy standards.

Not all states currently have the organizational capacity and institutional depth to design and deliver regulatory schemes of this nature, as well as the resource-intensive consultation processes which often accompany them.

So, as an increasing number of states ponder how to ‘futureproof’ their regulation of tomorrow’s technology – whether 6G, quantum computing or biotechnology – there is a need for capacity building in governments both on the theory of anticipatory governance and on how it can be applied in practice to global technology regulation.

Facebook's power under scrutiny as Trump ban upheld Expert comment NCapeling 6 May 2021

Keeping Donald Trump’s Facebook ban in place shows the vast power social media platforms hold, raising questions of whether that power is appropriately used.

Kate Jones

From a human rights perspective, the Oversight Board’s decision is a strong one, and not at all surprising. The board decided Facebook was right to suspend the former president’s access to post content on Facebook and Instagram, but not indefinitely.

It found Donald Trump’s posts violated Facebook’s community standards because they amounted to praise or support of people engaged in violence and that, applying a human rights assessment, Facebook’s suspension of Trump was a necessary and proportionate restriction of his right to freedom of expression.

However the board also found Trump’s indefinite suspension was neither in conformity with a clear Facebook procedure nor consistent with its commitment to respect human rights. Its decision requires Facebook to make a new decision on the future of Donald Trump’s account, grounded in its rules.

While opinions on this result will differ, the increased call for clear and accessible rules and respect for human rights in their implementation that the Oversight Board brings to Facebook’s operations is welcome.

But the Oversight Board’s powers are limited to content moderation – Facebook declined to answer the board’s questions about amplification of Trump’s posts through the platform’s design decisions and algorithms. This limitation on the board’s role should be lifted. It is in content amplification, not just content moderation, that Facebook should face scrutiny and accountability for the sake of the human rights of its users.

Fundamentally, human rights is not a veneer which can mask or legitimize underlying power dynamics or public policy – those still fall to be assessed for themselves.

The Trump/Facebook saga does highlight the vast power Facebook and other major social media platforms have over political discussion and persuasion. Through granting or denying, or through amplifying or quietening the voices of political figures, Facebook has the power to shape politics, electorates, and democratic processes. Improving content moderation through the Oversight Board, although important, does little to constrain that power.

Facebook itself, unlike a government, has no accountability to the general public, and the Oversight Board must not distract us from the need for a full conversation about the extent to which Facebook’s power is appropriately held and properly wielded.

Emily Taylor

This decision marks a coming of age for Facebook’s content moderation process. For years, decisions to take down content or ban users have been opaque, conducted by a human workforce that Facebook and other platforms have been hesitant to acknowledge. The platforms have also been worried that being seen to exercise an editorial function might put at risk the legal protections which prevent the platforms being held responsible for user-generated content.

When the Oversight Board was first posited, observers questioned whether a body funded by Facebook could properly exercise a legitimate appeals function. Now there is a reasoned decision which partly supports the decision to de-platform a serving president, but also takes issue with the indefinite nature of the ban.

Facebook specifically asked the Oversight Board to consider specific challenges involved when the person involved is a political leader. The board concluded that Trump’s ‘status as head of state with a high position of trust not only imbued his words with greater force and credibility but also created risks that his followers would understand they could act with impunity’. The storming of the US Capitol and role President Trump played in stirring up the violence underlined that political leaders’ words can motivate others to take harmful actions.

Just as the events of January 6 remain shocking, it remains shocking that private platforms have exercised the power to curb the speech of a US president. It also remains shocking that the platforms sat back and took no action over the previous four years, but waited until the final days of the transition.

The board’s decision is an evolution in private-sector content moderation, with a diverse board giving a reasoned opinion on a Facebook decision. But to fully comply with the principles of open justice, board decisions should include more detail on the individuals who have made the decision – at present, it appears all members of the board review the decision but it is not clear which individuals were involved in its drafting, or that they were clear from conflicts. If the process is to gain respect as a truly independent oversight on the platform’s decisions, greater transparency over the identity of decision-makers will be needed.

Mark Zuckerberg expressed concern about Facebook becoming an arbiter of truth or free speech and, overall, the difficulty of having private companies managing the application of fundamental rights on their platforms has not been solved. Just because companies have the financial resources to do it, does not mean they necessarily should.

Yet no other international governance or arbitration system has emerged to handle the complexities of platform power over speech. In the context of that vacuum, the Oversight Board’s decision is a welcome step.

Monitoring of trade deals needs a risk-based approach Expert comment NCapeling 24 May 2021

On human rights issues, trading partners must do more than trust to luck.

The recent row within the UK government about the treatment of agricultural products in a proposed new trade deal with Australia provides a reminder that changes to trading arrangements can have social and environmental costs, as well as benefits.

Although the UK government clearly feels political pressure to demonstrate its ‘Global Britain’ credentials with some speedily concluded new deals, rushing ahead without a full understanding of the social, environmental, and human rights implications risks storing up problems for later. In the meantime, calls for better evaluation and monitoring of trade agreements against sustainability-related commitments and goals – ideally with statutory backing – will only get stronger.

EU experiences with these kinds of processes are instructive. For more than 20 years the Directorate General for Trade of the European Commission (DG Trade) has been commissioning sustainability impact assessments (SIAs) from independent consultants in support of trade negotiations, and since 2012 these assessments have explicitly encompassed human rights impacts as a core part of the analysis.

These processes have since been augmented with a programme of periodic ‘ex post’ evaluations of trade agreements to ‘analyse the observed economic, social, human rights, and environmental impacts’ of live trade deals and to make recommendations about any mitigation action which may be needed.

For credibility and objectivity, the Commission outsources much of its sustainability assessment and ex post evaluation activities to independent consultants, who are encouraged to innovate and tailor their approaches subject to broad methodological parameters laid down by the Commission. Over time, experiences with specific assessment and monitoring assignments have enabled external SIA practitioners – and the Commission itself – to progressively strengthen these processes and underlying methodologies.

Yet despite the improvements there remains legitimate questions about whether the human rights aspects of these SIA processes – and subsequent evaluations – are having real policy impact. The difficulty of predicting human rights impacts of trade agreements in advance – as the COVID-19 crisis amply demonstrates – suggests a need for realism about the extent to which a ‘one off’ process, often carried out at a time when there is only ‘agreement in principle’ as to future trading terms, can produce a robust roadmap for heading off future human rights-related risks.

Human rights impact assessments have a potentially valuable role to play in laying down the substantive and structural foundations for future human rights monitoring as part of a broader, iterative, human rights risk management strategy. But the fragmented manner in which many trade agreements approach human rights issues, and the fact that outcomes are the product of negotiation rather than necessarily design, make it difficult to turn this vision into reality.

Controversies surrounding the SIA process for the EU-Mercosur agreement illustrate why striving for more coherence in the identification and subsequent management of human rights-related risks is important. In June 2019, the Commission decided to wrap up negotiations with the South America Mercosur bloc, even though the SIA process for the proposed agreement was still incomplete and the interim and final SIA reports yet to be delivered. Frustrated NGOs made their feelings clear in the form of a formal complaint – and a slap on the wrist from the EU Ombudsman duly followed.

However, when it eventually appeared in December 2020, the final SIA report for the EU-Mercosur deal did include a number of interesting recommendations for responding to specific areas of human rights-related risk identified through the pre-signing assessment process – such as flanking measures designed to address issues pertaining to health, equality, and protection of indigenous peoples, and stressing the need for ‘continuous monitoring’.

Hopefully these recommendations will be proactively followed up, but there are reasons not to be overly optimistic about that. To the extent that these recommendations might have required, or benefitted from, some tweaks to the terms of the trade agreement itself, it was clearly too late. And while there may be opportunities for EU institutions to follow up the recommendations through unilateral ex post evaluation processes, current legal, policy, and institutional arrangements provide few guarantees this will take place.

The credibility of the EU SIA programme has clearly taken a knock because of the problems with the EU-Mercosur process, and stakeholders could be forgiven for questioning whether expending time and effort on engaging in these processes is actually worthwhile. As a first step towards rectifying this, the Commission should be transparent about how it plans to respond to the EU-Mercosur SIA recommendations regarding flanking measures and follow up – ideally consulting with stakeholders about the various human rights monitoring options available.

Looking further ahead, the Commission should be urging SIA practitioners to deal more expansively with the options for follow up human rights monitoring in future SIA reports, setting out recommendations not just on the need for ongoing monitoring of human rights-related issues but on the detail of how this might be done, and how progress towards human rights-related goals could be tracked. And creativity should be encouraged because, as detailed in a newly-published Chatham House research paper, there may be more opportunities for human rights monitoring than first appear.

The SIA process could also provide a forum for exploring complementary measures needed to make future monitoring efforts as effective as possible – jointly and unilaterally; politically, structurally, and resources-wise; both within the framework of the trading relationship and extraneously. The credibility of the process – and hence stakeholder trust – would be further enhanced by commitments from the Commission to be more transparent in future about how different human rights monitoring recommendations laid out in SIAs have been taken into account in subsequent negotiations, in the supervisory arrangements developed for specific trading relationships, and in the implementation of EU trade policy more generally.

Learnings must become practice as the Taliban return Expert comment NCapeling 7 September 2021

There is greater awareness of the adverse impact of counterterrorism measures and sanctions on humanitarian action. It is time to apply lessons learned.

The 9/11 attacks prompted the international community to adopt a wide range of counterterrorism measures. Debate continues over their compliance with international humanitarian law (IHL) and human rights law, and their effectiveness.

What has become clear is that some of these measures have made it difficult for humanitarian assistance to be provided to the millions of people living in areas under the control of armed groups designated as terrorist, or where such groups have a significant presence.

These include Al-Qaeda in Yemen’s Arabian peninsula, ISIL affiliates in Syria, Al Shabaab in Somalia, Boko Haram in Nigeria, Hamas in Gaza, and various Al-Qaeda affiliates in the Sahel. The lessons painfully learned need to be applied to Afghanistan under Taliban rule.

Impeding humanitarian work

Traditionally, legal counterterrorism measures criminalized acts of violence but, in recent years, measures adopted by the UN Security Council, the European Union (EU), and some states unilaterally, have expanded to address broader forms of support for terrorist acts and to groups designated as terrorist.

When these measures apply in situations of armed conflict – and in the absence of adequate safeguards – they can impede humanitarian organizations from operating as foreseen by IHL and in accordance with humanitarian principles, which require life-saving assistance to be provided in an impartial manner. Restrictions in sanctions imposed for policy objectives other than counterterrorism create similar tensions.

Prohibitions on making funds or other assets available directly or indirectly to persons or groups designated as terrorist can capture incidental payments made during humanitarian operations and relief consignments which are diverted and end up in the hands of these designated groups.

The most extreme restrictions cover the provision of medical assistance, in violation of the foundational principle of IHL that everyone who is wounded and sick – civilian or fighter – is entitled to medical care without discrimination, and those who provide it must not be punished.

Humanitarian organizations have been highlighting these problems for more than a decade. Recent developments give cause for cautious optimism that a turning point has been reached, as the bodies imposing counterterrorism measures and sanctions internationally and domestically have begun to demand compliance with international law and IHL.

In 2019 the UN Security Council unanimously issued a binding demand to member states to ensure all counterterrorism measures they adopt comply with obligations under international law, including IHL.

Recent renewals of UN country-specific sanctions have included similar demands with regards to measures taken by member states to give effect to them. Although this still falls short of an express exception for humanitarian action, it is a significant development, and a strong encouragement to include appropriate safeguards when implementing UN measures domestically.

Similar encouraging practice is discernible at EU level, and new domestic counterterrorism laws adopted by several states include safeguards for humanitarian action.

Applying lessons learned to Afghanistan

It is too soon to know what policies the Taliban will adopt, and the measures that the international community will take to promote compliance with IHL, human rights, and counterterrorism objectives. Nonetheless, policymakers implementing sanctions – and considering their expansion – cannot ignore their potential adverse impact on humanitarian action. They must bear in mind five key lessons.

First, there must be clarity on current legal restrictions, starting from who is designated under sanctions and counterterrorism measures. The UN Security Council has never designated the Taliban per se. Instead, it has listed ‘individuals, groups, undertakings and entities associated with the Taliban’. At present this list includes 135 individuals and five entities, four of which are ‘hawalas’ – money changers – the other being the Haqqani Network, a Sunni Islamist group.

UN financial sanctions require states to freeze the assets of designated persons and groups and ensure no funds, financial assets, or economic resources are made available to them, either directly or indirectly.

EU and UK sanctions simply replicate the restrictions and designations imposed by the UN, but the US has designated the Taliban as a ‘specially designated global terrorist’ which makes the Global Terrorism Sanctions Regulations applicable. These prohibit US nationals from making any contribution or provision of funds, goods, or services to, or for, the benefit of the Taliban.

Second, while listed individuals may play a role in the forthcoming Taliban administration, sanctions do not prohibit providing resources to a government department headed by a designated person.

There is a distinction between an individual and a department, and prohibitions in counterterrorism measures or sanctions on the provision of funds or other assets apply to the designated person, not to the department they may head.

Problems may arise if a designated person appropriates resources for personal benefit or to undermine policy objectives for which the sanctions were imposed. But this does not bring the department within the scope of the designation. Instead, the issue must be addressed from a prevention of diversion perspective.

Third, sanctions and counterterrorism measures must be designed so as to minimize their adverse impact on humanitarian action. One way of doing so is designating leadership figures rather than groups. The new US administration took this approach towards the Houthi in Yemen, with the designation of the group being revoked and new designations focusing on its leaders.

The chilling effect of sanctions is far broader than the actual restrictions they impose. Commercial actors in particular limit their activities in areas they perceive as high risk. In view of this, the effect of expanding existing designations to list the Taliban, now that it is in control of Afghanistan, would be to turn targeted sanctions into comprehensive ones.

In parallel, sanctions or counterterrorism measures should include express safeguards, which exclude funds, assets, and other support provided during humanitarian action from the restrictions – ideally in the form of exceptions or, if an option, general licences.

The adverse impact of the US Global Terrorism Sanctions has been limited until now, as only a small number of humanitarian actors subject to US measures operated in areas under Taliban control. This has now changed, and it is imperative the US issue a broad general licence to exclude assistance provided during humanitarian action from the sanctions.

Fourth, restrictions in funding agreements must not be more onerous than the underlying measures they aim to promote compliance with – in particular, they must not require screening or exclusion of final beneficiaries from the assistance they have been determined as requiring.

Finally, engagement with non-state armed groups for humanitarian purposes is essential for conducting operations effectively and safely, both for humanitarian organizations and the people they are trying to assist. Counterterrorism measures and sanctions do not prohibit such contact even when such groups or their members have been designated.

The past two decades have given states ample time to learn to avoid the adverse impact of sanctions and counterterrorism measures on humanitarian action. The people of Afghanistan deserve that these lessons now be applied.

Our research paper IHL and the humanitarian impact of counterterrorism measures and sanctions identifies the principal points of friction between these bodies of law, clarifies outstanding issues and misunderstandings, and offers practical recommendations for resolving tensions.

The trickle-up effect of rights-based climate litigation Expert comment NCapeling 16 November 2021

With governments failing in their pledges and companies accused of ‘green-washing’, human rights-based litigation is increasingly important for accountability.

Tuvalu’s foreign minister addressing COP26 while standing knee-deep in seawater was a stark illustration of how the climate emergency directly and imminently threatens the most basic human rights protected under international law – including to the right to life, self-determination and cultural rights.

Human rights are now a fundamental component of more than 90 per cent of the climate litigation currently taking place outside the US, highlighting the international reach of human rights law and how its emphasis on protecting the most vulnerable helps diverse communities find common arguments for shared goals.

Cases are set to continue and to evolve but three types of claim are emerging, each of which is examined in a new Chatham House briefing paper.

1. Enforcing commitments

One category of cases seeks to hold states accountable for pledges they have made on climate change, such as emission reduction targets made under the framework of the 2015 Paris Agreement. Drawing on human rights obligations, governments can be charged with not taking sufficient steps to implement these pledges.

The case of Leghari v Pakistan (2015) concerned the government’s failure to carry out the National Climate Change Policy of 2012 and the Framework for Implementation of Climate Change Policy (2014-2030). The Lahore High Court held that several of the human rights enshrined in Pakistan’s constitution cover climate change and ‘provide the necessary judicial toolkit to address the government’s response to climate change’.

The court ordered the government to carry out measures such as publishing an adaptation action plan realizable within a few months of the order and establishing a Climate Change Commission to monitor progress.

2. Positive duties to mitigate risks

Many rights-based climate cases are being brought to clarify the scope of states’ positive duties under human rights law to take meaningful steps to protect their citizens against foreseeable risks to life and other rights.

This ‘trickle-up’ effect of human rights was prominent in the case of State of the Netherlands vs the Urgenda Foundation (2019) where the Dutch Supreme Court held that reducing emissions with the highest possible level of ambition amounts to a ‘due diligence standard’ for states to comply with their positive duties to adopt adequate measures to address climate change. Human rights law was also used by the court to fill in the content of the due diligence standards.

There is also a growing trend for rights-based actions to be brought against corporations, such as a recent case which drew on the UN Guiding Principles on Business and Human Rights to define the parameters of Shell’s duty of care and due diligence obligations in relation to carbon emissions under Dutch law. The court ordered Shell to reduce emissions by a net rate of 45 per cent by the end of 2030 – relative to 2019 figures – through its group corporate policy.

3. Avoiding harm in climate action

The global human rights regime is also increasingly invoked in litigation concerning states’ negative obligations to ensure that their climate mitigation and adaptation activities do not themselves contribute to human rights violations (including discrimination) and that states prioritize adaptation measures for those most at risk in a just and equitable way.

As Chatham House’s paper makes clear, this kind of litigation ‘puts pressure on governments to expand their approach to tackling climate change beyond purely a regulatory one to a more holistic strategy’.

Closing the climate justice gap

Climate and environmental litigation grounded in human rights is set to continue given the overwhelming scientific evidence of risks associated with human-induced climate change and the limited confidence in pledges made by states and corporations alike – including those made recently at COP26.

A growing collaboration between civil society organizations and vulnerable communities in relation to both the protection of nature and the enjoyment of their land and cultural rights was evident at COP26, and this alliance will add further momentum to the trend for rights-based climate litigation based on the rights of indigenous and other vulnerable communities, especially on issues such as deforestation.

But more challenges are coming. International human rights law recognizes a duty of international cooperation but there remain significant hurdles for climate-vulnerable communities in developing countries to compel action by richer nations despite the vast debts of ‘carbon colonialism.’

One big issue is the problem of extraterritoriality, as the extent to which states owe obligations to individuals outside their territory is contested. Courts in both Germany and the Netherlands have rejected claimants from developing countries in domestic class actions on this basis. But a recent decision of the UN Committee on the Rights of the Child on a complaint brought by Greta Thunberg and other youth activists against five countries opens the door for further litigation.

One of a number of cases being brought by youth claimants across the world, the committee concluded that a state’s human rights duties can – in some instances – extend to children in other countries. This includes any activities on the territory that host states have the power to prevent from causing ‘transboundary harm’ – such as emissions from the territory – where these activities ‘significantly’ impact the enjoyment of human rights of persons outside the territory.

To date, high-profile rights-based cases have argued for policy change and stronger targets underpinned by binding legislation responsive to the science. Claims are set to become more complex and contested. Building on scientific developments in climate attribution, rights-based litigation is now tackling other difficult questions such as apportioning responsibility and remedial action.

These cases examine both historically high emitters and the public and private actors who either continue specific activities or refrains from action in the face of the overwhelming science linking human activities such as extraction and burning of fossil fuels to deforestation and climatic consequences.

Courts are also likely to explore the duties that states and corporations owe to deliver a ‘just transition’ away from carbon-intensive industries, given the benefits of growth and climate action are already unevenly distributed.

A holistic human-rights based approach

Several states together with civil society are leading the charge for global recognition of the right to a healthy, clean, and sustainable environment in the United Nations (UN) Human Rights Council, and multi-stakeholder processes are defining what effective corporate due diligence looks like.

In addition, UN-appointed special rapporteurs are delivering practical guidance on how to devise solutions which are fair, non-discriminatory, participatory, and climate-resilient without exacerbating inequality – including difficult issues of planned relocation – and UN Human Rights Treaty Bodies are unpacking the duty of international cooperation to act in good faith to address loss and damage.

Recently the Committee on the Elimination of Discrimination Against Women recommended the Marshall Islands, in order to meet its duty to its citizens, should actively seek international cooperation and assistance – including climate change financing – from other countries but in particular the US, whose ‘extraterritorial nuclear testing activities have exacerbated the adverse effects of climate change and natural disasters’ in the islands.

Reactive oxygen species (ROS) are an unavoidable host environmental cue for intracellular pathogens such as Mycobacterium tuberculosis and Mycobacterium bovis; however, the signaling pathway in mycobacteria for sensing and responding to environmental stress remains largely unclear. Here, we characterize a novel CmtR-Zur-ESX3-Zn2+ regulatory pathway in M. bovis that aids mycobacterial survival under oxidative stress. We demonstrate that CmtR functions as a novel redox sensor and that its expression can be significantly induced under H2O2 stress. CmtR can physically interact with the negative regulator Zur and de-represses the expression of the esx-3 operon, which leads to Zn2+ accumulation and promotion of reactive oxygen species detoxication in mycobacterial cells. Zn2+ can also act as an effector molecule of the CmtR regulator, using which the latter can de-repress its own expression for further inducing bacterial antioxidant adaptation. Consistently, CmtR can induce the expression of EsxH, a component of esx-3 operon involved in Zn2+ transportation that has been reported earlier, and inhibit phagosome maturation in macrophages. Lastly, CmtR significantly contributes to bacterial survival in macrophages and in the lungs of infected mice. Our findings reveal the existence of an antioxidant regulatory pathway in mycobacteria and provide novel information on stress-triggered gene regulation and its association with host–pathogen interaction.

Hepatocyte nuclear factor-1β (HNF-1β) is a tissue-specific transcription factor that is required for normal kidney development and renal epithelial differentiation. Mutations of HNF-1β produce congenital kidney abnormalities and inherited renal tubulopathies. Here, we show that ablation of HNF-1β in mIMCD3 renal epithelial cells results in activation of β-catenin and increased expression of lymphoid enhancer–binding factor 1 (LEF1), a downstream effector in the canonical Wnt signaling pathway. Increased expression and nuclear localization of LEF1 are also observed in cystic kidneys from Hnf1b mutant mice. Expression of dominant-negative mutant HNF-1β in mIMCD3 cells produces hyperresponsiveness to exogenous Wnt ligands, which is inhibited by siRNA-mediated knockdown of Lef1. WT HNF-1β binds to two evolutionarily conserved sites located 94 and 30 kb from the mouse Lef1 promoter. Ablation of HNF-1β decreases H3K27 trimethylation repressive marks and increases β-catenin occupancy at a site 4 kb upstream to Lef1. Mechanistically, WT HNF-1β recruits the polycomb-repressive complex 2 that catalyzes H3K27 trimethylation. Deletion of the β-catenin–binding domain of LEF1 in HNF-1β–deficient cells abolishes the increase in Lef1 transcription and decreases the expression of downstream Wnt target genes. The canonical Wnt target gene, Axin2, is also a direct transcriptional target of HNF-1β through binding to negative regulatory elements in the gene promoter. These findings demonstrate that HNF-1β regulates canonical Wnt target genes through long-range effects on histone methylation at Wnt enhancers and reveal a new mode of active transcriptional repression by HNF-1β.

Histone recognition by “reader” modules serves as a fundamental mechanism in epigenetic regulation. Previous studies have shown that Spindlin1 is a reader of histone H3K4me3 as well as “K4me3-R8me2a” and promotes transcription of rDNA or Wnt/TCF4 target genes. Here we show that Spindlin1 also acts as a potent reader of histone H3 “K4me3-K9me3/2” bivalent methylation pattern. Calorimetric titration revealed a binding affinity of 16 nm between Spindlin1 and H3 “K4me3-K9me3” peptide, which is one to three orders of magnitude stronger than most other histone readout events at peptide level. Structural studies revealed concurrent recognition of H3K4me3 and H3K9me3/2 by aromatic pockets 2 and 1 of Spindlin1, respectively. Epigenomic profiling studies showed that Spindlin1 colocalizes with both H3K4me3 and H3K9me3 peaks in a subset of genes enriched in biological processes of transcription and its regulation. Moreover, the distribution of Spindlin1 peaks is primarily associated with H3K4me3 but not H3K9me3, which suggests that Spindlin1 is a downstream effector of H3K4me3 generated in heterochromatic regions. Collectively, our work calls attention to an intriguing function of Spindlin1 as a potent H3 “K4me3-K9me3/2” bivalent mark reader, thereby balancing gene expression and silencing in H3K9me3/2-enriched regions.

Pyruvate kinase muscle isoform 2 (PKM2) is a key glycolytic enzyme and transcriptional coactivator and is critical for tumor metabolism. In cancer cells, native tetrameric PKM2 is phosphorylated or acetylated, which initiates a switch to a dimeric/monomeric form that translocates into the nucleus, causing oncogene transcription. However, it is not known how these post-translational modifications (PTMs) disrupt the oligomeric state of PKM2. We explored this question via crystallographic and biophysical analyses of PKM2 mutants containing residues that mimic phosphorylation and acetylation. We find that the PTMs elicit major structural reorganization of the fructose 1,6-bisphosphate (FBP), an allosteric activator, binding site, impacting the interaction with FBP and causing a disruption in oligomerization. To gain insight into how these modifications might cause unique outcomes in cancer cells, we examined the impact of increasing the intracellular pH (pHi) from ∼7.1 (in normal cells) to ∼7.5 (in cancer cells). Biochemical studies of WT PKM2 (wtPKM2) and the two mimetic variants demonstrated that the activity decreases as the pH is increased from 7.0 to 8.0, and wtPKM2 is optimally active and amenable to FBP-mediated allosteric regulation at pHi 7.5. However, the PTM mimetics exist as a mixture of tetramer and dimer, indicating that physiologically dimeric fraction is important and might be necessary for the modified PKM2 to translocate into the nucleus. Thus, our findings provide insight into how PTMs and pH regulate PKM2 and offer a broader understanding of its intricate allosteric regulation mechanism by phosphorylation or acetylation.

A New Era for China: Implications for the Global Mining and Metals Industries 18 June 2018 — 9:00AM TO 10:30AM Anonymous (not verified) 8 June 2018 Chatham House, London

Since the turn of the century, China’s demand for resources has dominated global headlines. It’s rapid demand growth through the early 2000s sparked the beginning of the commodities ‘super cycle’, and encouraged a growing Chinese presence in international mining, and in global metals and minerals markets. More recently, its transition toward the ‘new normal’ of slower but higher quality growth has underpinned the sudden slowdown in global commodities demand.

Drawing on China’s domestic ambitions, as set out in the 19th party congress, and on its wider strategic ambitions through the Belt and Road Initiative, the speaker will set out his thoughts on China’s next era of growth, and its likely implications for international mining investment and global metals and minerals markets.

The Global Implications of China's Energy Revolution 4 March 2019 — 9:00AM TO 10:30AM Anonymous (not verified) 7 February 2019 Chatham House | 10 St James's Square | London | SW1Y 4LE

Ten years ago, it would have been difficult to believe that China – the world’s largest greenhouse gas emitter – would be one of the global leaders in some elements of clean energy development and deployment. With increasing air pollution and predominantly coal-fired power generation fueled by a booming economy and population, China has had to rethink its approach to environmental protection and climate mitigation.

Strong government signalling and national policies have led to the construction of the world’s largest fleets, wind farms and solar photovoltaic arrays in an effort to reduce national GDP intensities of energy and CO2 emissions. How has the availability of large amounts of capital, and the number of state-owned companies with soft budgetary constraints, helped contribute to this?

Against this backdrop, this event will consider how China must re-evaluate its approach to energy security – coal made up the majority of the country’s energy in 2016, followed by oil, of which 65 per cent had to be imported – despite the country being one of the pioneers of renewable energy. This event will look at how, in delivering on its clean energy objectives, China could redefine the traditional energy security paradox and in fact become more resilient to previously overlooked vulnerabilities.

Plant-based 'Meat' and Cultured Meat: Revolutionizing the Livestock Sector 10 April 2019 — 4:00PM TO 5:30PM Anonymous (not verified) 14 March 2019 Chatham House | 10 St James's Square | London | SW1Y 4LE

Consensus is building across the scientific, environmental and public health communities that a radical shift away from excessive meat-eating patterns is urgently needed to tackle the unsustainability of the livestock sector. Recognizing the scale of the challenge ahead, public policymakers, civil society and innovators have increasingly sought to prompt shifts in consumer food choices – away from the most resource-intensive meat products and towards more sustainable alternatives.

Meat analogues – plant-based ‘meat’ and cultured meat also known as ‘lab-grown’ meat – mark a departure from traditional meat alternatives. Both are intended to be indistinguishable from – and in the case of cultured meat biologically equivalent to – animal-derived meat and are marketed principally at meat-eaters. Innovation and investment in meat analogues have increased significantly, but the direction and pace of growth in the meat analogue industry will depend upon a multitude of factors, including public acceptance, civil society support and incumbent industry responses.

This event will explore the challenges of scaling up production and generating demand for meat alternatives. It will also look at the ways policymakers in the UK and EU can impact the direction of the industry while examining what factors will influence consumer acceptance of plant-based ‘meat’ and cultured meat as substitutes for animal-derived meat.

Sino-Russian Gas Cooperation: Power of Siberia I and II and Implications for Global LNG Supplies 27 November 2019 — 8:30AM TO 9:30AM Anonymous (not verified) 19 November 2019 Chatham House | 10 St James's Square | London | SW1Y 4LE

In a new event in the Sustainable Transitions series, the speaker will present an update of Sino-Russian gas cooperation.

To give a comprehensive account of their impact on global liquefied natural gas (LNG) supplies, he will discuss the following points:

• Gas is scheduled to start flowing from the Power of Siberia I (POS) on 2 December 2019. But what is the background of development of POS 1 and what is its current status and prospects?
• What are the chances of exporting gas through the proposed Altai pipeline? Why is the Mongolia export route so significant? And how will it affect the Central Asian Republics and in particular Turkmenistan’s gas export to China?
• What are the implications of both POS I and Altai gas via Mongolia route in the context of global LNG supply?
• What are the prospects for multilateral pipeline gas cooperation in northeast Asia?
• What are the implications for other Arctic onshore LNG supply, in particular, for Novatek’s Yamal LNG and Arctic LNG 1 and 2 to China on top of POS 1 and Altai gas?

Attendance at this event is by invitation only.

Impact of the US Election on Global Climate Politics 25 November 2020 — 1:00PM TO 2:00PM Anonymous (not verified) 16 November 2020 Online

Panellists discuss how Joe Biden’s victory will impact international efforts to tackle climate change. Will climate finally become a common area for global cooperation?

Joe Biden’s victory over Donald Trump is already having a positive impact on international efforts to tackle climate change. Leaders from across the world, including the UK, Canada, Australia and Fiji, have used their first messages to the President-elect to draw attention to the climate crisis.

Biden has promised to re-join the global community in its commitment to the Paris Agreement – but this could be the easy part. More difficult will be whether and how Biden is able to deliver his ambitious climate plan, and how effectively he is able to integrate climate change into foreign policy efforts and national security strategies.

Global climate action has also moved forward in the last four years. The European Union recently pledged to become climate neutral by 2050, and China, Japan and South Korea have committed to achieving carbon neutral economies.

How will the US re-enter this global landscape of distributed leadership and what difficulties does it face? Will the US be willing to work within a competitive partnership with the EU and China? How will Biden’s win change the dynamic of COP26 next year? 

From local to global: A roadmap for US climate action 14 April 2021 — 6:30PM TO 8:00PM Anonymous (not verified) 28 March 2021 Online

Ahead of Biden’s Earth Day Summit, panellists discuss a range of climate issues, from city-level climate management to the international security implications of climate deals.

On their first day in office, the Biden-Harris administration sent a strong message to Americans and allies by rejoining the Paris Agreement. Experienced climate and environmental leaders were appointed to senior leadership roles as part of a ‘whole of government approach’ to climate action.

Although decisive action is welcomed by many Americans and international partners, the divided domestic perspectives on climate and a changed international landscape pose significant challenges.

Ahead of the Earth Day Summit on April 22, an event hosted by Joe Biden to mark America’s formal return to global climate talks, panellists discuss a range of climate issues, from city-level climate management to the international security implications of climate deals.

• How will post-COVID domestic priorities and policy influence the international approach of the US to climate action?
• How will US policy, both foreign and domestic, need to respond to the security and geopolitical elements posed by climate change?
• What actions are needed during the upcoming Earth Day Summit for the US to establish credibility as a climate leader?
• What shape are key debates taking on US-China climate relations ahead of COP 26, and how might climate issues be approached in relation to wider geopolitical tensions?

Combatting Human Trafficking: The Situation in East Asia 16 September 2019 — 10:30AM TO 5:30PM Anonymous (not verified) 30 August 2019 Taipei, Taiwan

In 2017, there were an estimated 40.3 million victims of modern slavery worldwide. The prevalence for individuals to fall victim to forced labour practices is highest in the Asia-Pacific region where four out of every 1,000 people have been found to be victims of forced labour and labour trafficking. Many of these victims end up in the more developed economies of East Asia as destination countries of labour trafficking. Such cases are, however, often under-reported and under-detected, largely owing to a lack of a coherent response to trafficking across the sub-region.

At this roundtable, organized in partnership with the Taiwan Foundation for Democracy, the Taiwan-Asia Exchange Foundation and the University of Portsmouth, participants will discuss emerging anti-trafficking practices from a regional perspective including legal and policy frameworks and the role of business and recruitment agencies.

Attendance at this event is by invitation only.

Bangladesh: The Trade-Off Between Economic Prosperity and Human Rights 11 March 2020 — 1:00PM TO 2:00PM Anonymous (not verified) 28 February 2020 Chatham House | 10 St James's Square | London | SW1Y 4LE

Bangladesh’s recent gains in economic and social indices, set against its record of corruption and poor civil rights, has at times been termed the ‘Bangladesh Paradox’. Yet this label is overly simplistic; the current situation proves that these trends can coexist.

The Awami League government, in power since 2009, has increased political stability, delivered unprecedented economic and social advances, and adopted a counter-terrorism strategy to stamp out extremist groups. At the same time, it is criticized for curbing civil rights and failing to hold credible elections. However, as the two previous regimes have demonstrated, the rights situation is unlikely to improve even if the Awami League were replaced.

How did worsening rights become a feature of the state irrespective of its political dispensation? An unresolved contest between political and non-political state actors may hold the key to that puzzle. The perils of the current dispensation have recently manifested in weakening economic indicators, which jeopardize the very stability and social progress for which the country has garnered much praise.
