at US–China Strategic Competition: The Quest for Global Technological Leadership By feedproxy.google.com Published On :: Wed, 06 Nov 2019 18:26:46 +0000 7 November 2019 The current dispute between the US and China goes far beyond trade tariffs and tit-for-tat reprisals: the underlying driver is a race for global technological supremacy. This paper examines the risks of greater strategic competition as well as potential solutions for mitigating the impacts of the US–China economic confrontation.

President Trump has raised a number of issues regarding trade with China – including the US’s trade deficit with China and the naming of China as a currency manipulator. But at the heart of the ongoing tariff escalation are China’s policies and practices regarding forced technology transfer, intellectual property theft and non-market distortions.As China’s international influence has expanded it has always been unlikely that Beijing would continue to accept existing global standards and institutions established and widely practised by developed countries based on ‘the Washington Consensus’.China’s desire to be an alternative champion of technology standard-setting remains unfulfilled. Its ample innovation talent is a solid foundation in its quest for global technology supremacy but tightening controls over personal freedoms could undermine it and deter potential global partners.It is unclear if Chinese government interventions will achieve the technological self-sufficiency Beijing has long desired. China’s approach to macroeconomic management diverges significantly from that of the US and other real market economies, particularly in its policy towards nurturing innovation.Chinese actors are engaged in the globalization of technological innovation through exports and imports of high-tech goods and services; cross-border investments in technology companies and research and development (R&D) activities; cross-border R&D collaboration; and international techno-scientific research collaboration.While the Chinese state pushes domestic companies and research institutes to engage in the globalization of technological innovation, its interventions in the high-tech sector have caused uneasiness in the West.The current US response to its competition with China for technological supremacy, which leans towards decoupling, is unlikely to prove successful. The US has better chances of success if it focuses on America’s own competitiveness, works on common approaches to technology policy with like-minded partners around the globe and strengthens the international trading system.A technically sound screening mechanism of foreign investment can prevent normal cross-border collaboration in technological innovation from being misused by geopolitical rival superpowers.

Estimates from June 2019 have placed the number of migrants at nearly double of what they were in 2018 with the increase in numbers stemming from a lack of economic opportunity combined with a rise in crime and insecurity in the region. The impacts of migration can already be felt within the affected states as the exodus has played a significant role in weakening labour markets and contributing to a ‘brain drain’ in the region. It has also played an increasingly active role in the upcoming US presidential election with some calling for more security on the border to curb immigration while others argue that a more effective strategy is needed to address the sources of migration. What are the core causes of Central American migration and how have the US, Central American and now also Mexican governments facilitated and deterred migration from the region? Can institutions be strengthened to alleviate the causes of migration? And what possible policy alternatives and solutions are there that could alleviate the pressures individuals and communities feel to migrate? Anita Isaacs, professor of Political Science at Haverford College and co-director of the Migration Encounters Project, and Juan Ricard Ortega, principal advisor for Central America at the Inter-American Development Bank, will join us for a discussion on the core drivers of migration within and across Central America.Attendance at this event is by invitation only.

at 'The Truth is, Chile is Unequal': What's Behind Chile's Protests By feedproxy.google.com Published On :: Tue, 17 Dec 2019 19:33:39 +0000 18 December 2019 Dr Christopher Sabatini Senior Research Fellow for Latin America, US and the Americas Programme @ChrisSabatini LinkedIn Lyndsey Jefferson Digital Editor, Communications and Publishing Department @LyndseyLdn As part of a series on global protests, Dr Christopher Sabatini tells Lyndsey Jefferson why Chileans are taking to the streets. GettyImages-1177498531.jpg A demonstrator waves a Chilean flag during a protest in Santiago on 21 October 2019. Photo: Getty Images. Why are these protests happening now?The truth is, Chile is unequal, even though it actually reduced poverty from 1989, the time of the democratic transition, until today, from 40% to 16%.There are a number of reasons for the protests. One is the most proximate cause, which is the increase in the subway fares, but that really doesn’t explain the underlying tensions.One of those tensions is despite reductions in poverty, social mobility remains a large problem in Chile. It remains a very elitist country with limited social mobility. So, poverty may be reduced, but the likelihood that someone in the working middle class would reach the upper middle class has always been a stretch.The second issue is a lack of political change. The last four presidents were the same two people.Chile’s been governed, with the exception of Piñera, basically by the same political coalition, La Concertación, which is a combination of the Christian Democratic and Socialist parties. Piñera came from the right, an outside party, but even he has remained. There has been no renewal of the political leadership which again reinforces that lack of social mobility. Do the protesters have any other demands or grievances? The demands are amorphous and that’s part of the issue – they’re going to be difficult to meet. People are expressing a genuine desire for change but what would that change mean?Chileans don’t necessarily want to change the economic model; they simply want more mobility. That’s difficult to do and these are untested demands. Chileans also want political reform. What Piñera offered is to rewrite the constitution, which was created under military government in 1980. Other than some changes here and there in terms of the electoral system and reduction of military power, it has pretty much remained intact.Will constitutional change really address these demands? It’s simply a document that may create the rules for how power is allocated and conducted, but it’s not going to dramatically remake Chilean society.You mentioned inequality as a key driver of the protests. Can you expand a bit more on the current economic situation of ordinary Chileans?Chile is going to grow at only around 2-3%, but it was growing at around 4-5% earlier. A lot of those funds were ploughed into social programmes that have since been reduced. Chile’s economy really boomed in the early 2000s because of Chinese demands of Chilean imports. But as with any sort of commodities-based economy, the jobs it provides tend to be lower wage.As a result, despite the fact that Chile tried to diversify its economy by investing in entrepreneurship and innovation, it hasn’t grown in a way that provides jobs that many associate with upward mobility. As Chile's economy cooled, its ability to lift people out of poverty lagged as well. Demonstrators hold placards depicting eyes – in reference to police pellets hitting demonstrators' eyes – during a protest in Santiago on 10 December 2019. Photo: Getty Images. Two major issues for the protesters are education and pensions – can you explain why this is?These are two issues of the economic and social model that was held up at one time as being a model for the region, the neoliberal models that are really coming under question and are in some ways at the heart of this.One is the privatized pension system which is failing to produce the returns that retirees need to survive. The second is the education system. Chile created a voucher system where parents can shop around and send their kids to the best schools. The idea was to create competition among schools to improve.The problem was like any market, it created a certain amount of inequality among schools. There was a problem of some schools underperforming and being relegated poorer performing students, or students being forced to go to those schools because the more successful schools were already spoken for. At the end of October, the government announced a series of social reforms. Will this be enough to satisfy the protesters’ demands?Social reforms may address some of the issues of insufficient pensions or lack of quality education, but it will take a while for them to have an effect.The second thing is, social reforms don’t address the issues of power. At the heart of this is this idea of closed economic, political and social power. That comes about through economic growth and how you break up concentrations of wealth. Social reforms aren’t going to do that, although they’ll help on the margins. We’re seeing horrific scenes of police violence against protesters and dozens of people have died. Has this deterred the protesters in any way? No, in many ways it has sort of inspired them. It has, I think, sustained the protests.We’re not talking massive repression and tanks rolling in like Tiananmen Square. We’re talking about tear gas, rubber bullets, some injuries and deaths, and even credible reports of torture.It’s funny you should mention this – a class I’m teaching today is about social media and protests. One of the central arguments is that successful social protests need a martyr; they need a rallying cry.The deaths and the repression sort of help sustain that, but moreover, social media helps communicate what’s happening through videos and pictures. It really helps maintain this sense of righteousness, disdain for the government, and this idea of the need to demand change.Where do you see this going next?I don’t think we know. In the 60s and 70s, the political scientist Samuel Huntington argued in Political Order in Changing Societies that as economies grow, political institutions often strain to contain and channel demands. I think we’re seeing this now.This social ferment over political, economic and social demands is uncharted water. I don’t know where this will go, but I think we’ll see a change in the constitution. We’ve already seen a fragmenting of the party system, which I think will continue. Hopefully, that will lead to new leadership that can help reflect a change in Chile itself. Full Article
at The UK, US and Mauritius: Decolonization, Security, Chagos and the ICJ By feedproxy.google.com Published On :: Wed, 22 Jan 2020 13:35:01 +0000 Invitation Only Research Event 30 January 2020 - 8:15am to 9:15am Chatham House | 10 St James's Square | London | SW1Y 4LE Event participants Professor Philippe Sands QC, Professor of Law, UCL Richard Burt, Managing Partner, McLarty AssociatesChair: Dr Leslie Vinjamuri, Director, US and Americas Programme; Dean, Queen Elizabeth II Academy, Chatham House The Chagos archipelago in the Indian Ocean has garnered media attention recently after the UK failed to abide by a UN deadline to return the islands to Mauritius. The US has landed in the middle of the dispute as a 1965 agreement with the UK has allowed the US to establish a military base on one of the islands, Diego Garcia, which has since become instrumental in US missions in the Asia-Pacific and the Middle East. In February 2019, an Advisory Opinion of the International Court of Justice (ICJ) found that the Chagos archipelago was unlawfully dismembered from Mauritius, in violation of the right to self-determination and that the United Kingdom is under an obligation to end its administration of the Chagos archipelago ‘as rapidly as possible’. The UN General Assembly subsequently voted overwhelmingly in favour of the UK leaving the islands by the end of November 2019 and the right of the former residents who were removed by the UK to return. The UK does not accept the ICJ and UN rulings and argues that the islands are needed to protect Britain from security threats while Mauritius has made clear the base can remain.Professor Philippe Sands QC, professor of law at University College London and lead counsel for Mauritius on the ICJ case on Legal Consequences of the Separation of the Chagos archipelago from Mauritius in 1965, will be joining Ambassador Richard Burt, US chief negotiator in the Strategic Arms Reduction Talks with the former Soviet Union for a discussion on the fate of the archipelago including the future of the military base and the right of return of former residents.

Since assuming office, President Trump has withdrawn the US from the Joint Comprehensive Plan of Action, withdrawn troops from Syria, relocated the US embassy in Israel to Jerusalem and orchestrated the strike against ISIS leader Abu Bakr al-Baghdadi.Against a backdrop of Trump's inclination towards withdrawing from the region, countries across the Middle East are being rocked by protests, Turkey’s purchase of Russia’s S-400 missile has threatened to undermine cohesion within NATO and the much hoped for ceasefire in Libya between UN-backed government leader, Fayez al-Sarraj, and opposition leader, Khalifa Haftar, failed to materialize.In light of the upcoming US elections in November 2020, the future of US national security policy promises to be a prominent issue for the next administration. In this vein, the US and Americas Programme at Chatham House plans a yearlong focus on the pivotal US 2020 elections.At this event, Dr Kori Schake, director of foreign and defense policy studies at the American Enterprise Institute will discuss the future of US foreign policy towards the Middle East. How have domestic and party politics in the US – and the unfolding presidential campaign – shaped recent policy decisions by the Trump administration? Should we expect policy objectives in the Middle East to remain consistent or shift under a second Trump term? And what direction could US foreign policy towards the region take under a Democratic administration?Attendance at this event is by invitation only.

This may force Europe to make difficult choices between the two economic superpowers – or perform a balancing act. Although the recent US-China phase-1 trade deal has eased the relationship for now, the trade and technology tensions are a structural issue and are likely to persist.The debate over Huawei’s participation in 5G networks is an example of how the UK and other countries may face competing priorities in economic, security and foreign policy. Can Europe avoid a binary choice between the US and China? Is it possible for the EU to position itself as a third global power in trade, technology and standard-setting? What strategies should Europeans adopt to keep the US and China engaged in the rules-based international order and what does the future hold for trade multilateralism?Sir Simon Fraser will join us for a discussion on Europe’s future role between the US and China. Sir Simon is Managing Partner of Flint Global and Deputy Chairman of Chatham House. He previously served as Permanent Secretary at the Foreign and Commonwealth Office (FCO) and Head of the UK Diplomatic Service from 2010 to 2015. Prior to that he was Permanent Secretary at the UK Department for Business, Innovation and Skills.

In December 2018, Andrés Manuel López Obrador (AMLO) was inaugurated as Mexico’s 58th president. The following month saw another political shift further south, as Jair Bolsonaro became Brazil’s 38th president. While sitting on opposite ends of the political spectrum, both AMLO and Bolsonaro were considered to be political outsiders and have upended the status quo through their election to office. To what extent does the election of AMLO in Mexico and Bolsonaro in Brazil represent a shift in those countries’ definitions of national interest and foreign policy priorities? How will this affect these states’ policies regarding international commitments and cooperation on issues such as human rights, environment and climate change, migration, and trade? To what extent do possible shifts reflect changing domestic opinions? Will any changes represent a long-term shift in state priorities and policies past these administrations?

With these fifteen, simultaneously-held state elections, the Democrats hope to have greater clarity about their party’s likely nominee for the general race against President Donald Trump in November. Concerns around intraparty divisions in the Democratic party between progressives (represented by Senators Elizabeth Warren and Bernie Sanders) and moderates (represented by former Vice President Joe Biden and former mayor Pete Buttigieg) have surrounded the primary races so far, and are unlikely to dissipate even if one candidate emerges from the field on 3 March.Against this backdrop, Chatham House brings together a panel of experts to discuss the state of the Democratic primary race, implications for the general election, and the Trump campaign’s priorities ahead of its re-election bid. Will the Democratic party resolve its divisions and unite behind a progressive or moderate in light of the Super Tuesday election results? How is Trump positioned to fair against the Democratic candidates left in the race? Did Former Mayor of New York Michael Bloomberg’s primary gamble to focus on Super Tuesday pay off?

Since his election in 2016, US President Donald Trump has presided over economic expansion and record unemployment rates following a 2017 tax overhaul and deregulation policies. Trump’s approval rating is at the highest level of his presidency, while on the Democratic side, the once-wide field is in a process of narrowing as intra-party ideological differences persist. As we look ahead to the presidential elections in November 2020, Dr Lindsay Newman will reflect on Donald Trump’s presidency, the state of the 2020 election and preview the potential directions of travel ahead under a Trump 2.0 or a Democratic administration. How can we understand the health of Trump’s presidency post-impeachment and post-State of the Union address? What will Trump’s likely foreign policy priorities be ahead of his re-election bid including prospects for a US-UK or a US-Europe trade deal?

Latin America’s agricultural powerhouses Brazil and Argentina only accounted for a total of 1.6% of the UK’s agricultural market across eight sectors in 2018, all of those areas in which Argentina and Brazil have substantial comparative advantages. Conversely, UK exports to the large Latin American economies remain far below their potential. To cite a few examples, in 2018 in the electrical equipment sector, the UK only exported $95.7 million of those products to Brazil, making the ninth largest economy in the world only the 42nd export market for those goods from the UK; Mexico only imported $91.4 million of UK-made electrical goods, placing it directly behind Brazil as UK’s market for those goods.As we look to the future, any improvement to the relationship will depend on two factors: 1) how the UK leaves the EU and 2) whether Latin American agricultural producers can improve their environmental practices and can meet the production standards established by the EU and likely maintained by a potential post-Brexit Britain.In the first meeting of the working group, Chatham House convened a range of policymakers, practitioners and academics to explore this topic in depth, identify the key issues driving this trend, and begin to consider how improvements might best be made. Subsequent meetings will focus on specific sectors in commerce and investment.We would like to thank BTG Pactual, Cairn Energy plc, Diageo, Equinor, Fresnillo Management Services, HSBC Holdings plc and Wintershall Dea for their generous support of the Latin America Initiative.

at Immature leadership: Donald Trump and the American presidency By feedproxy.google.com Published On :: Wed, 04 Mar 2020 13:20:12 +0000 4 March 2020 , Volume 96, Number 2 Read online Daniel W. Drezner There has been a renaissance in the study of how the backgrounds of individual leaders affect foreign policy outcomes. Donald Trump's presidency highlights the limits of this approach. Trump's psychology is so unique, and so akin to that of a small child, that studying his background alone is insufficient to explain his decision-making. The evidence for this characterization of Trump's leadership comes not from his political opponents, but his allies, staffers and subordinates. Trump's lack of impulse control, short attention span and frequent temper tantrums have all undercut his effectiveness as president as compared to his predecessors. Nonetheless, the 45th president helps to clarify ongoing debates in American politics about the relative strength of the presidency as an institution. In particular, the powers of the presidency have become so enhanced that even comparatively weak and inexperienced leaders can execute dramatic policy shifts. The formal checks on presidential power, from the legislative, judicial and executive branches have all eroded. Similarly, the informal checks on the presidency had also degraded before Trump's inauguration. This article uses Trump's presidency—and his severe limitations as a decision-maker—to highlight the ways in which even a weak leader can affect change by holding a powerful office. Full Article
at Civil society perspectives on sexual violence in conflict: patriarchy and war strategy in Colombia By feedproxy.google.com Published On :: Wed, 04 Mar 2020 13:31:21 +0000 4 March 2020 , Volume 96, Number 2 Anne-Kathrin Kreft Read Online In international policy circles, conflict-related sexual violence (CRSV) is commonly viewed as a weapon of war, a framing that researchers have criticized as overly simplistic. Feminist scholars in particular caution that the ‘weapon of war’ framing decontextualizes sexual violence in conflict from the structural factors of gender inequality that underpin its perpetration. In light of these tensions, how do politically relevant local actors perceive the nature and the origins of conflict-related sexual violence? Civil society organizations often actively confront conflict-related sexual violence on the ground. A better understanding of how their perceptions of this violence align or clash with the globally dominant ‘weapon of war’ narratives therefore has important policy implications. Interviews with representatives of Colombian women's organizations and victims' associations reveal that these civil society activists predominantly view conflict-related sexual violence as the result of patriarchal structures. The mobilized women perceive sexual violence as a very gendered violence that exists on a continuum extending through peace, the everyday and war, and which the presence of arms exacerbates. Strategic sexual violence, too, is understood to ultimately have its basis in patriarchal structures. The findings expose a disconnect between the globally dominant ‘weapon of war’ understanding that is decontextualized from structural factors and a local approach to CRSV that establishes clear linkages to societal gender inequality.

Photo by Win McNamee/Getty Images. As the US surgeon general warns Americans to brace for ‘our Pearl Harbor moment’, the US faces a week in which it may see the worst of the global pandemic. The absence of US leadership at the global level has enabled the Security Council’s inaction. And at the G7, President Trump actively obstructed efforts to agree a joint statement.US efforts to increase its support of international aid to the tune of $274million are minimal, not least in light of a 50% reduction in its support for the World Health Organization (WHO) and radically diminished support for other global health programmes as well. International coordination is essential to mitigate unregulated competition for critical medical supplies, manage border closures, and guarantee international economic stability.True, it won’t be possible to control the epidemic at home if the global effort to defeat the pandemic fails. But the absence of leadership from Washington at home is palpable. And what happens at home sets a natural limit on America’s internationalism.Both solution and problemIn response to the coronavirus crisis, the US state is proving to be a solution - and a problem. The dramatic response to the economic crisis is evident with the $2.3trillion stimulus package signed into law by President Trump boldly supported by both Democrats and Republicans in the most significant piece of bipartisan legislation passed in decades.America’s political economy is unrecognisable, moving left and looking increasingly more European each week as Congress and the executive branch agree a series of stimulus packages designed to protect citizens and businesses. Some elements of this legislation were more familiar to Americans, notably $200bn in corporate tax breaks.But Congress also agreed unemployment insurance, and cheques - one in April, one in May – to be sent directly to those Americans most directly hit by the economic impact of COVID-19. In effect, this is adopting a temporary universal basic income.The stimulus plan also dedicated $367bn to keep small businesses afloat for as long as the economy is shuttered. Already the government is negotiating a fourth stimulus package, but the paradox is that without rigorous steps to halt the health crisis, no level of state intervention designed to solve the economic response will be sufficient.The scale of the state’s economic intervention is unprecedented, but it stands in stark contrast to Washington’s failure to coordinate a national response to America’s health crisis. An unregulated market for personal protective equipment and ventilators is driving up competition between cities, states, and even the federal government.In some cases, cities and states are reaching out directly beyond national borders to international organisations, foreign firms and even America’s geopolitical competitors as they search for suppliers. In late March, the city of New York secured a commitment from the United Nations to donate 250,000 protective face masks.Now Governor Cuomo has announced New York has secured a shipment of 140 ventilators from the state of Oregon, and 1,000 ventilators from China. The Patriots even sent their team plane to China to pick up medical supplies for the state of Massachusetts. And following a phone call between President Putin and President Trump, Russia sent a plane with masks and medical equipment to JFK airport in New York.Networks of Chinese-Americans in the United States are rapidly mobilising their networks to access supplies and send them to doctors and nurses in need. And innovative and decisive action by governors, corporates, universities and mayors drove America’s early response to coronavirus.This was critical to slowing the spread of COVID-19 by implementing policies that rapidly drove social distancing. But the limits of decentralized and uncoordinated action are now coming into sharp focus. President Trump has so far refused to require stay-at-home orders across all states, leaving this authority to individual governors. Unregulated competition has driven up prices with the consequence that critical supplies are going to the highest bidder, not those most in need.Governor Cuomo’s call for a nationwide buying consortium has so far gone unheeded and, although the Federal Emergency Management Agency has attempted to deliver supplies to states most in need, the Strategic National Stockpile is depleting fast. Without critical action, the federal government risks hindering the ability of cities and states to get the supplies they need.But President Trump is reluctant to fully deploy his powers under the Defense Production Act (DPA). In March, he did invoke the DPA to require certain domestic manufacturers to produce ventilators. But calls for it to be used to require manufacturers to produce PPE (personal protective equipment), control costs, and manage allocations has so far gone unheeded by a president generally opposed to state interventions for managing the economy.It is true that federalism and a deep belief in competition are critical to the fabric of US history and politics, and innovations made possible by market values of entrepreneurism and competition cannot be underestimated. In the search for a vaccine, this could still prove to be key.But with current estimates that more Americans will die from coronavirus than were killed in the Korean and Vietnam wars combined, it is clear now is the time to reimagine and reinvent the role of the American state.In the absence of a coordinated effort driven by the White House, governors are working together to identify the areas of greatest need. Whether this will lead to a recasting of the American state and greater demand for a deeper and more permanent social safety net is a key question in the months ahead.In the short-term the need for coordinated state action at the national level is self-evident. US leadership globally, to manage the health crisis and its economic impacts, is also vital. But this is unlikely to be forthcoming until America gets its own house in order. Full Article

The Appellate Body’s demise in December 2019 led to a renewed focus on the future of the WTO. But the challenges facing the WTO run deeper than that – the organization has lost relevance as a negotiation forum, resulting in the global trade rules not having kept pace with changes in technology and the rise of China. While the WTO provides a forum for international cooperation to address the trade fallout from COVID-19, what implications will the pandemic have for the long-term reform of the global trade system?Both the US and EU have proposed various WTO reform strategies and taken steps towards collaboration, but is a transatlantic partnership for WTO reform feasible? Do the US and EU believe that a rules-based international trade system is in their interest – especially in light of COVID-19? What are the biggest issues dividing the US and EU on reforming the WTO, and is there a common assessment of the key problems? What steps can the US and EU take to address the dispute settlement function of the WTO and to modernize the trade rules? Are there broader issues, such as environmental and social sustainability, that should be included in a transatlantic agenda for WTO reform?This event is part of the Chatham House Global Trade Policy Forum and will take place virtually only.We would like to take this opportunity to thank founding partner AIG and supporting partners Clifford Chance LLP, Diageo plc, and EY for their generous support of the Chatham House Global Trade Policy Forum.

at Reimagining Trade Rules to Address Climate Change in a Post-Pandemic World By feedproxy.google.com Published On :: Fri, 24 Apr 2020 10:25:01 +0000 Webinar Research Event 5 May 2020 - 2:00pm to 3:00pm Event participants James Bacchus, Distinguished University Professor of Global Affairs and Director of the Center for Global Economic and Environmental Opportunity at the University of Central Florida; Member and Chair, WTO Appellate Body, 1995 - 2003Chair: Creon Butler, Director, Global Economy and Finance Programme, Chatham House This event is part of the Chatham House Global Trade Policy Forum and will take place virtually only.International trade has a crucial role to play in tackling climate change. The production and transport of goods is a major contributor to green-house gas emissions, as is the delivery of certain cross-border services. At the same time, it looks inevitable that the COVID-19 pandemic will lead to a radical re-think of global supply chains as companies and governments seek to build in greater resilience while at the same time preserving as far as possible the efficiency gains and lower costs that global supply chains generate when operating normally.Future international trade rules will have a crucial role to play in addressing both challenges; they represent both an opportunity and a risk. If designed well, they could play a very important role in re-enforcing moves towards a more sustainable use of resources, greater overall alignment of economies with the Paris Agreement, and greater economic resilience. But they could also, if poorly designed and implemented, or overly influenced by strategic political considerations, have significant unintended and negative implications. These include: reduced economic efficiency, increased poverty, unnecessary economic decoupling and reduced consensus on the broader mitigation and adaptation measures required to meet the challenge of climate change.Against this background, a number of key questions arise: In what areas, if any, do we need to modify or adapt key principles underlying the system of global trade rules in order to respond to the twin challenges of responding to climate change and building greater economic resilience? Which are the most promising/practical areas on which trade policy experts should focus now to re-launch/re-energize discussions on WTO reform, including, for example, dispute settlement? What national economic policies will be needed to complement the development of new/reformed trade disciplines in these areas? How might future political changes, such as a change in the US administration, affect the prospects for and political momentum behind such deliberations? What in any eventuality is the best way to build the required political momentum?

at Latin America’s COVID-19 Moment: Differences and Solidarity By feedproxy.google.com Published On :: Thu, 30 Apr 2020 11:37:25 +0000 30 April 2020 Dr Christopher Sabatini Senior Research Fellow for Latin America, US and the Americas Programme @ChrisSabatini LinkedIn There has been no better example of the political diversity in Latin America than the varying responses of governments to the coronavirus crisis. 2020-04-30-Chile-Covid.jpg A municipal cleaning worker disinfects the central market in Santiago, Chile on 7 April 2020 amid the coronavirus pandemic. Photo: Getty Images. Differing approaches across the hemisphere have had different impacts on presidential popularity and, at least in one case, on democratic institutions and human rights. Yet, even within that diversity, South America’s Southern Cone countries (Argentina, Chile, Paraguay and Uruguay) have shown a sign of solidarity: protecting and facilitating trade flows, sponsoring cross-border research and ensuring citizens’ return to their home countries. The response from populist leadersOn the extreme have been the responses of presidents of Brazil, Nicaragua and Mexico, all of whom have ignored the science of the virus and of experts and refused to implement isolation policies. President Jair Bolsonaro of Brazil fired his health minister, Luis Henrique Mandetta on 16 April for contradicting him and earlier had claimed that the pandemic was a hoax or little more than a ‘measly cold.' Meanwhile, Nicaraguan president Daniel Ortega has resisted closing businesses and schools. After a mysterious 34-day absence, Ortega appeared on television on 15 April reinforcing his refusal to close businesses saying that Nicaraguans must work or they will die and claiming that the virus was ‘imported.’ Mexico’s Andres Manuel Lopez Obrador (AMLO) has also resisted the call for strict stay-at-home policies, though with his Deputy Health Minister, Hugo López-Gatell, has closed schools – recently extending the closure to the 1st of June and urging non-essential businesses to close – but focusing primarily on social distancing. In contrast to his deputy health minister and Foreign Minister Marcelo Ebrard – who had declared the situation a health emergency on 30th March, later than many neighbouring countries – AMLO has largely attempted to avoid discussion of the pandemic, claiming that in his case he has lucky charms that prevent him from contracting the virus. And both Bolsonaro and AMLO have participated in large public rallies, doing all the things that politicians love, shaking hands and hugging babies, and in the case of the former even wiping his nose before embracing an elderly woman.The Nicaraguan, Brazilian and Mexican presidents make an odd grouping since one (Bosonaro) is considered of the extreme populist right and the others (Ortega and AMLO) of the populist left. What unites them is good old-fashioned populism, a belief in a leader who represents the amorphous popular will and should be unfettered by checks and balances on his power, including something like… science. An eclectic groupAt the other extreme have been the quick responses by governments in Peru, Argentina, Chile, El Salvador and Colombia which put quarantine measures in place in mid-March. In these cases, governments have even banned outdoor activities and in the case of Peru and Colombia (in the large cities) have imposed alternating days for when women and men can leave the house so as to better control outside movement. This too, though, is an eclectic group. It includes a Peronist president Alberto Fernández in Argentina, conservative presidents Sebastian Piñera in Chile and Ivan Duque in Colombia, interim president and relative political neophyte Martin Vizcarra in Peru and outsider president Nayib Bukele in El Salvador. El Salvador’s strict quarantine measures have led to rising concerns that Bukele is using the crisis to consolidate personal power, using the national police and the armed forces to enforce the quarantine and ignoring three rulings by the Supreme Court urging the president to end the abuses. In Argentina, Peronist Fernández has shown a surprising commitment to containment even as it hurts his party’s working-class base, not something typically expected of the populist Peronist Party. In all of these cases, the quick, strong responses by the presidents shored up their popularity. Peru’s Vizcarra saw his popularity shoot up 35 points in a week to 82 per cent according to surveys taken in March. In late March 2020, Fernández in Argentina saw his approval ratings swell to 79.2 per cent with 94.7 percent of citizens approving of the government’s strict shelter-at-home policies. Even presidents Piñera and Duque who had struggled with low approval ratings throughout 2019 and saw those numbers sink even lower after the social protests that ended the year have seen their numbers rise. According to an 20th April poll, Piñera’s popular approval rating swelled from 13 percent in March 18th at the start of the crisis to 25 per cent by 20th April; while hardly a sweeping popular mandate, even that level was unthinkable only a few months ago when administration was battered by social protests. In Colombia, after a series of political missteps and the popular protests, Duque’s popular approval rating had slumped to 26 per cent; by April 2nd, 62 percent of Colombians supported the once-beleaguered president. (No recent surveys were available for Bukele in El Salvador.)In contrast, Bolsonaro’s in Brazil has only nudged up. Before the crisis hit, the president’s popularity had been in steady decline from a high of 49 per cent in January 2019 to 30 per cent by early December 2019. But by the first week in April, in the midst of a crisis in which other presidents saw their approval ratings increase by double digits, after his public disagreements with the health minister, Bolsonaro’s had sunk to 33 per cent while the soon-to-be-fired Mandetta’s stood at 76 per cent. AMLO in Mexico has fared no better. The populist leftist scored a high 86 per cent approval rating in February 1, 2019. By March 28, 2020 with concerns over his weak and flippant COVID-19 response and a severe contraction in economic growth, AMLO’s approval rating had sunk 26 points to 60 per cent and his disapproval stood at 37 per cent. In the midst of disharmony, coordinationDespite these differences, many countries in the region have shown the solidarity they often speak of but rarely follow in policy or practice. Peru, Chile and other countries have collaborated in repatriating citizens back to their home countries in the midst of the crisis. Even the countries of the Southern Cone common market, MERCOSUR, have pulled together on a number of fronts. The trade bloc had effectively been ruled a dead-man-walking after its failed efforts to integrate Venezuela into the bloc, lowering its standards to let in the petroleum dependent semi-authoritarian government of then President Hugo Chávez. Even on the basics of internal cooperation, the block was struggling, unable to coordinate monetary policies and non-tariff trade barriers between the original founding member states, Argentina, Brazil, Paraguay and Uruguay.The 35-year-old customs union seemed to get a breath a new life with the announcement that it had concluded 20-year-long negotiations with the EU for a free trade deal. Ratification of that deal, however, ran aground on the political differences between the recently elected governments of Bolsonaro in Brazil and the Peronist Fernández in Argentina. Bolsonaro refused to attend the Fernández December 2019 inauguration, in protest of the newly elected president’s leftist leanings. And this was well before their sharply divergent reactions to the COVID-19 virus. How surprising then that Mercosur has served as an effective coordination mechanism for these different and once opposed governments. The trade body is collaborating among member states to ensure the repatriation of citizens and has agreed to coordinate to ensure that trade flows, especially of medical supplies, are not interrupted by shutdown measures. Mercosur has even gone one step further than several other bodies have failed to take. In early April the bloc’s governing body, based in Montevideo, Uruguay created a $16 million (12 million pound) fund to augment country research and assist in the purchase of supplies needed to combat the virus. Now if Brazil, Argentina and the others could only coordinate their domestic coronavirus responses and economic policy. In late March Fernández announced he was pulling Argentina out of a possible Mercosur-EU trade deal. Full Article

at Learning the ABCs of ATP release [Signal Transduction] By feedproxy.google.com Published On :: 2020-04-17T00:06:05-07:00 ATP plays important roles outside the cell, but the mechanism by which it is arrives in the extracellular environment is not clear. Dunn et al. now show that decreases in cellular cholesterol levels mediated by the ABCG1 transporter increase ATP release by volume-regulated anion channels under hypotonic conditions. Importantly, these results may imply that cells that handle cholesterol differently might experience differential extracellular ATP release during hypotonicity. Full Article
at ABC transporters control ATP release through cholesterol-dependent volume-regulated anion channel activity [Signal Transduction] By feedproxy.google.com Published On :: 2020-04-17T00:06:05-07:00 Purinergic signaling by extracellular ATP regulates a variety of cellular events and is implicated in both normal physiology and pathophysiology. Several molecules have been associated with the release of ATP and other small molecules, but their precise contributions have been difficult to assess because of their complexity and heterogeneity. Here, we report on the results of a gain-of-function screen for modulators of hypotonicity-induced ATP release using HEK-293 cells and murine cerebellar granule neurons, along with bioluminescence, calcium FLIPR, and short hairpin RNA–based gene-silencing assays. This screen utilized the most extensive genome-wide ORF collection to date, covering 90% of human, nonredundant, protein-encoding genes. We identified two ABCG1 (ABC subfamily G member 1) variants, which regulate cellular cholesterol, as modulators of hypotonicity-induced ATP release. We found that cholesterol levels control volume-regulated anion channel–dependent ATP release. These findings reveal novel mechanisms for the regulation of ATP release and volume-regulated anion channel activity and provide critical links among cellular status, cholesterol, and purinergic signaling.

at G{alpha}q splice variants mediate phototransduction, rhodopsin synthesis, and retinal integrity in Drosophila [Signal Transduction] By feedproxy.google.com Published On :: 2020-04-24T06:08:45-07:00 Heterotrimeric G proteins mediate a variety of signaling processes by coupling G protein–coupled receptors to intracellular effector molecules. In Drosophila, the Gαq gene encodes several Gαq splice variants, with the Gαq1 isoform protein playing a major role in fly phototransduction. However, Gαq1 null mutant flies still exhibit a residual light response, indicating that other Gαq splice variants or additional Gq α subunits are involved in phototransduction. Here, we isolated a mutant fly with no detectable light responses, decreased rhodopsin (Rh) levels, and rapid retinal degeneration. Using electrophysiological and genetic studies, biochemical assays, immunoblotting, real-time RT-PCR, and EM analysis, we found that mutations in the Gαq gene disrupt light responses and demonstrate that the Gαq3 isoform protein is responsible for the residual light response in Gαq1 null mutants. Moreover, we report that Gαq3 mediates rhodopsin synthesis. Depletion of all Gαq splice variants led to rapid light-dependent retinal degeneration, due to the formation stable Rh1-arrestin 2 (Arr2) complexes. Our findings clarify essential roles of several different Gαq splice variants in phototransduction and retinal integrity in Drosophila and reveal that Gαq3 functions in rhodopsin synthesis.

at S-Palmitoylation of the sodium channel Nav1.6 regulates its activity and neuronal excitability [Cell Biology] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 S-Palmitoylation is a reversible post-translational lipid modification that dynamically regulates protein functions. Voltage-gated sodium channels are subjected to S-palmitoylation and exhibit altered functions in different S-palmitoylation states. Our aim was to investigate whether and how S-palmitoylation regulates Nav1.6 channel function and to identify S-palmitoylation sites that can potentially be pharmacologically targeted. Acyl-biotin exchange assay showed that Nav1.6 is modified by S-palmitoylation in the mouse brain and in a Nav1.6 stable HEK 293 cell line. Using whole-cell voltage clamp, we discovered that enhancing S-palmitoylation with palmitic acid increases Nav1.6 current, whereas blocking S-palmitoylation with 2-bromopalmitate reduces Nav1.6 current and shifts the steady-state inactivation in the hyperpolarizing direction. Three S-palmitoylation sites (Cys1169, Cys1170, and Cys1978) were identified. These sites differentially modulate distinct Nav1.6 properties. Interestingly, Cys1978 is exclusive to Nav1.6 among all Nav isoforms and is evolutionally conserved in Nav1.6 among most species. Cys1978 S-palmitoylation regulates current amplitude uniquely in Nav1.6. Furthermore, we showed that eliminating S-palmitoylation at specific sites alters Nav1.6-mediated excitability in dorsal root ganglion neurons. Therefore, our study reveals S-palmitoylation as a potential isoform-specific mechanism to modulate Nav activity and neuronal excitability in physiological and diseased conditions. Full Article
