Economy dips 8.9% in Q1

(To watch the whole media session with sign language interpretation, click here.)

 

Hong Kong's economy in the first quarter of 2020 contracted 8.9% over a year earlier, the largest decline on record since 1974.

 

The Census & Statistics Department announced the findings today as it released advance estimates on Gross Domestic Product for the first quarter.

 

Addressing the media today, Financial Secretary Paul Chan noted the economic recession deepened in Hong Kong in the first quarter of 2020.

 

“Although locally, the epidemic situation seems to be under control, but the external environment is still very challenging. Globally, the epidemic is yet to be put under complete control. That will affect our exports. That will also affect international travelling and business investments. 

 

“So, going forward in the second quarter, we believe that even if there is improvement, the improvement will be gradual and small.”

 

According to those estimates, private consumption expenditure decreased 10.2% in real terms in the first quarter from a year earlier, deteriorating from the 2.9% decline in the fourth quarter of 2019.

 

Government consumption expenditure grew 8.3% year-on-year, after the increase of 6.1% in the fourth quarter of 2019.

 

Gross domestic fixed capital formation dropped by 13.9%, compared with the decrease of 16.8% in the previous quarter.

 

Over the same period, total exports of goods declined 9.7% and imports of goods also fell 10.9%.

 

Exports of services dropped 37.8% and imports of services decreased 25.4%.

 

Mr Chan called on people to work together to promote economic development by consumption.

 

“If we are able to work together, if we can unite together - not just to fight the virus, but to stimulate consumption to promote economic development - I think the economic situation will be able to stabilise somewhat in the second quarter. 

 

“If the global epidemic situation improves, we will be able to come out of recession gradually towards the end of this year. 

 

“I will appeal to our people's support for us to roll out various measures in the Anti-epidemic Fund - round one and round two - as well as the relief packages in the 2020-21 Budget as soon as possible.

 

“Many of those initiatives are still yet to be implemented. Upon full implementation of those measures, I think the positive impact on the economy would be better felt by the community. We will be monitoring the situation carefully.”

 

The Government stands ready to roll out additional measures to support Hong Kong people and the businesses, Mr Chan added.

Catering business subsidy set

The Food & Environmental Hygiene Department announced that applications for the Catering Business (Social Distancing) Subsidy Scheme, under the second round of the Anti-epidemic Fund, will start from May 5.

 

The department said the scheme, which is estimated to benefit 16,000 catering outlets and their employees, will provide financial relief measures to the catering businesses which have been hard hit by the COVID-19 epidemic and social distancing measures.

 

It will provide subsidies ranging from $250,000 to $2,200,000 to eligible licence holders of general restaurants, light refreshment restaurants, marine restaurants and factory canteens in operation according to the floor area of the premises as specified on the licence.

 

The primary goal of the scheme is to support the payment of employees' salaries during a six-month period following application approval.

 

To provide immediate relief to the catering sector, the subsidy will be dished out upfront, in two tranches.

 

To avoid abuse, applicants should undertake that there will be no redundancy of staff for three months on receipt of the first tranche of subsidy and another three months on receipt of the second tranche.

 

They should also undertake that not less than 80% of the subsidies for respective months would be used to pay salaries of staff working at the premises.

 

Applicants should submit within a specified period a certificate issued by a Certified Public Accountant (practising) on its total staff salaries and total number of salaried staff for each of the months covered by the subsidy.

 

They should also submit a certificate issued by a CPA on its total staff salaries and total number of staff working at the premises for the month of March this year.

 

To avoid double benefits, applicants should declare that they have not and will not submit any application under the Employment Support Scheme.

 

Each catering outlet directed to close its licensed premises under the Prevention & Control of Disease (Requirements & Directions) (Business & Premises) Regulation, including karaoke establishments, nightclubs and bars or pubs, is eligible for a further one-off subsidy of $50,000.

 

Applications should be submitted to the department's District Environmental Hygiene Offices in person or by mail. Food licence holders can also submit their applications through the website.

 

The deadline for application is June 5.

 

Upon receipt of the completed application form and supporting documents and after verification, the disbursement of the first tranche of subsidies can generally be made in two to three weeks by crossed cheques to the corresponding licensed food premises.

Patrick Nip inspects public services

Secretary for the Civil Service Patrick Nip today visited the Transport Department (TD) and the Social Welfare Department (SWD) to learn more about the preparations made by both departments to resume public services.

 

The Government announced that the resumption of public services will start from May 4 under a phased approach.

 

While the TD will resume road tests on that day, written tests will resume on May 26.

 

The SWD will also gradually resume the services of its Integrated Family Service Centres (IFSC).

 

Mr Nip first visited the driving test centre in Ho Man Tin where he was briefed by the Commissioner for Transport Mable Chan on arrangements for the resumption of road tests and the implementation of infection control measures at driving test centres.

 

Such measures will require candidates to wear surgical masks and undergo body temperature screening at entrances.

 

As for the written tests, Mr Nip said he was pleased to learn that the TD will keep seats apart at appropriate distances and step up cleansing of computers at test centres.

 

Mr Nip then visited the Causeway Bay Integrated Family Service Centre where he was briefed on the plan to gradually resume services at IFSCs and measures to reduce social contact.

 

Mr Nip also learned that various infection control measures to safeguard the health of colleagues as well as service users will be put in place. For example, group activities will be conducted for no more than four participants and physical partitioning will be erected in meeting rooms for counselling services.

 

Mr Nip emphasised that many people hope that the Government can provide more public services when the epidemic situation becomes stable.

 

“I am pleased to learn that the departments have made all the necessary preparations for providing the services needed by the public while striving to safeguard public health.

 

“Government departments will continue to maintain a high degree of vigilance and adopt all the necessary precautionary measures. The Government will also closely monitor the situation and determine when to embark on a full resumption of normal business.”

 

Mr Nip expressed hope that the public will continue to fight the virus together with the Government.

 

He also thanked civil servants for their commitment and dedicated efforts to serve the public during the epidemic.

Complaints impartially probed

The Government has mechanisms to investigate complaints against civil servants impartially, Secretary for the Civil Service Patrick Nip said today.

 

Mr Nip made the remarks in response to media queries on recent allegations levelled against senior police officers.

 

He said: “There are established mechanisms to investigate every complaint in accordance with the procedures and rules. Depending on the circumstances and the case details, some are being handled by departments and bureaus. Some may be handled by the Civil Service Bureau.

 

“There are established mechanisms in dealing with that. Of course we would handle each and every complaint in a very serious and impartial manner.”

Drug delivery scheme examined

Secretary for Constitutional & Mainland Affairs Erick Tsang today visited the temporary operation centre for the special scheme for delivering urgently needed prescription medication to Hong Kong people in Guangdong and Fujian.

 

Under the compulsory quarantine arrangements, many Hong Kong people who are staying in Guangdong and Fujian provinces are unable to attend follow-up consultations in Hong Kong to replenish their prescription medication and return to the Mainland on the same day.

 

The Government introduced a special scheme on February 24 to deliver medicine to them, with priority given to those who would run out of prescription medication by end-April.

 

Mr Tsang was pleased to learn that as of April 29, prescription medication deliveries had been made to more than 7,600 Hong Kong residents in need.

 

He thanked the Hong Kong Federation of Trade Unions for offering voluntary services for the drug delivery scheme with its well-established service networks on the Mainland.

 

Mr Tsang also thanked the Pharmaceutical Society of Hong Kong and Hong Kong Pharmaceutical Care Foundation for deploying pharmacists to the temporary operation centre to help verify drug records and patients' information.

 

During his visit, he gave encouragement to participating volunteers and thanked them for their support for the scheme.

 

Mr Tsang said as the expiry date for the Compulsory Quarantine of Certain Persons Arriving at Hong Kong Regulation has been extended to June 7, the special scheme will be extended and give priority to cases in which prescription drugs will run out on or before that date.

 

Call 2343 2255 for enquiries about the scheme.

House Committee status explained

(To watch the full media session with sign language interpretation, click here.)

  

Chief Executive Carrie Lam today said the prevailing chairwoman of the Legislative Council House Committee should have the responsibility and power to deal with the matters of the committee.

 

Mrs Lam made the statement ahead of the Executive Council meeting this morning, noting LegCo President Andrew Leung had sought advice from outside senior counsel on how to address the delay in electing the committee’s chairman.

 

She said the senior counsels have observed that many of the matters raised in the House Committee’s meetings by the presiding member in the past six months have been irrelevant to the purpose of electing the committee’s chairman and vice-chairman.

 

“The second point that the senior counsels have observed during their very detailed scrutiny of the deliberations is that there was at least one occasion on March 13 in the House Committee meeting that gave people a very clear impression that the delaying of the election by the presiding member of the House Committee was quite deliberate and deliberate for political reasons.

 

“And the third thing that I observed from the senior counsels’ advice is, having regard to all these circumstances, they are of the firm view - this is the word taken from the senior counsels’ statement - that the prevailing chairwoman of the House Committee should have the responsibility and the power to deal with the business of the House Committee.”

 

The Chief Executive added that she expects the committee’s prevailing chairwoman Starry Lee to exercise her power.

HKEx chief not to seek reappointment

Hong Kong Exchanges & Clearing Limited (HKEx) today announced that Charles Li will not seek reappointment as Chief Executive at the end of his current contract in October 2021.

     

The Government said it respected Mr Li's decision and expressed deep appreciation for his exemplary contribution to the development of the financial market during his tenure as HKEx Chief Executive in the past decade.

 

Since taking the helm in January 2010, he has led HKEx and Hong Kong’s capital market in achieving important breakthroughs one after another.

 

The vibrancy and growth that Mr Li has brought to Hong Kong in the capital market helps reinforce the status of Hong Kong as a leading international financial centre.

 

Financial Secretary Paul Chan said: "Thanks to his vision and leadership, Mr Li has laid a solid and strong foundation for our stock market, rendering Hong Kong the largest IPO market in the world for seven times in the past 11 years.

 

"He has been instrumental in the successful launch of mutual market access programmes between Hong Kong and the Mainland, notably the Shanghai-Hong Kong Stock Connect in 2014, which was expanded to include Shenzhen-Hong Kong Stock Connect in 2016 and Bond Connect in 2017.

 

"He also played a pivotal role in the launch of new listing regime in Hong Kong, the enhanced internationalisation of HKEx and its international visibility. These are all important achievements of HKEx in the past few years under Mr Li’s able leadership."

Mr Chan added that the Government is confident the HKEx board will continue to ensure the success of HKEx in the years to come.

Policy studies funding announced

About $31 million in funding has been given to support 79 projects under the special round of the Public Policy Research (PPR) Funding Scheme, the Government announced today.

 

A total of 210 applications were received for the special round, which was launched last November to fund local research institutions and think tanks to research topics relating to the underlying causes of the social incidents that took place in the second half of 2019.

 

The research may also cover important political, economic, cultural and societal issues relating to deep-seated problems of society.

 

Assessment of the applications received under the special round was conducted by the independent assessment panel chaired by and comprising experienced academics.

 

The research quality of the proposal and relevance to the themes of the special round were the principal assessment criteria, with consideration given to factors such as whether the research proposal was solution-oriented, feasible and practical, whether the methodology was reasonable and sound, the applicant’s capability and whether the proposed budget was cost-effective. 

 

The assessment panel took a holistic view on each research proposal, reached a collective decision and made recommendations, the Policy Innovation & Co-ordination Office said, adding that a declaration of interest system was in place to ensure the assessments were fair and impartial.

 

In general, a sum of up to $500,000 has been granted to each approved project under the special round.

 

The approved projects have commenced progressively and are expected to be completed by the end of the year, with the first batch to be completed in late September to early October.

Police involved in offences arrested

Police today said it is highly concerned about recent criminal offences involving police officers and that a number of these officers have been arrested.

 

Among them, officers in connection with serious offences have been or will be interdicted.

 

The force said it is furious and disappointed about the officers who are suspected of having breached the law and that the incidents have impaired public confidence in Police.

 

Police attach the utmost importance to the discipline and integrity of officers.

 

All officers, irrespective of their ranks, must abide by the law at all times.

 

Police management has zero tolerance towards any acts that breach the law or discipline by police officers, it added.

 

The force also said it attaches great importance to the integrity of its officers.

 

The Complaints & Internal Investigations Branch formulated the Integrated Integrity Management Framework to promote integrity and honesty among officers as well as to regulate their discipline and conduct.

 

To avoid similar incidents, Police said its management is reviewing the force’s internal management strategy.

 

Police reiterated that no bad element in the force can be tolerated.

 

If an officer is suspected of having breached the law or committed a breach of discipline, Police will conduct an investigation according to the established mechanism and take appropriate actions.

Karin Melnick receives Birman Fellowship

Karin Melnick of the University of Maryland, College Park, has been awarded the AMS Joan and Joseph Birman Fellowship for Women Scholars for the 2020–2021 academic year.

Melnick’s research is on differential-geometric aspects of rigidity. This work comprises global and local results relating the automorphisms of a differential-geometric structure with the geometric and topological properties of the space. Melnick also works in smooth dynamics, in which an invariant differential-geometric structure plays an important role in the proof of rigidity theorems. Melnick is a leader in research on the Lorentzian Lichnerowicz conjecture, a statement about conformal transformations of compact Lorentzian manifolds. Together with collaborators, she has developed new techniques in the setting of Cartan connections that have facilitated progress on this problem, as well as many results for other differential-geometric structures and general parabolic Cartan geometries.  

Brief Biography of Karin Melnick:

Melnick received her PhD at the University of Chicago in 2006 under the direction of Benson Farb. With an NSF Postdoctoral Research Fellowship, she went to Yale University as a Gibbs Assistant Professor. She received a Junior Research Fellowship from the Erwin Schrödinger Institute in the spring of 2009 and that fall began at the University of Maryland, where she is now an associate professor. Previously, Melnick has been awarded an AMS Centennial Fellowship and an NSF CAREER grant. She divides her time between the U.S. and Germany with her partner and their young child, and is very grateful for the flexibility provided by the Birman Fellowship and the opportunities it provides to advance her research and career goals.  

About the Fellowship:

Established in 2017, the AMS Joan and Joseph Birman Fellowship for Women Scholars seeks to give exceptionally talented women extra research support during their mid-career years. The primary selection criterion for the Birman Fellowship, which carries a stipend of US$50,000, is the excellence of the candidate’s research. Read an interview with Joan Birman about her decision to create the Fellowship with the goal of "helping more women mathematicians to develop their creative voices."

Modeling COVID-19: A new video describing the types of models used

Below, Mac Hyman, Tulane University, talks about types of mathematical models--their strengths and weaknesses--the data that we currently have and what we really need, and what models can tell us about a possible second wave.

At the beginning of the video, he thanks the mathematics community for its work, and near the end says, "Our mathematical community is really playing a central role in helping to predict the spread, and help mitigate this epidemic, and prioritize our efforts. …Do not underestimate the power that mathematics can have in helping to mitigate this epidemic—-we have a role to play."

CE explains relaxation of measures

(To watch the full press conference with sign language interpretation, click here.)

 

The relaxation of anti-epidemic measures is a step in the right direction, Chief Executive Carrie Lam said today.

 

Mrs Lam made the statement at a press conference this afternoon.

 

She said the Government will relax the requirement limiting group gatherings in public places to a maximum of four people. Starting from Friday, up to eight people can gather in public places.

 

"So raising the number from four to eight for the catering business and also for the prohibition against group gatherings under Cap 599G is not an exact science, but this is a step in the right direction of relaxation.

 

"Maybe in another 14 days’ time we will raise the number of eight to 10, to 12, to 15 and so on."

 

Regarding bars and pubs, Mrs Lam said these venues will be able to reopen but the Government will put in place requirements to prevent physical interactions.

 

"We have decided that perhaps to strike a pragmatic balance is to allow them to reopen for business but to put in far more stringent requirements."

 

Such requirements include no live music, band performances or dancing in bar premises.

 

"That would be another way to keep the social distance and prevent as much as possible physical interactions."

CE inspects CuMask production

Chief Executive Carrie Lam inspected one of the CuMask production sites in Tsuen Wan today and expressed gratitude to those manufacturing the reusable masks for Hong Kong residents to fight against the COVID-19 epidemic.

 

She chatted with the staff and noted that many of them are retired textile industry workers who have re-joined the production workforce to combat the virus.

 

Mrs Lam praised them for their commitment to serving the community and thanked them for their hard work.

 

The masks produced in the workshop will be delivered to a clean workspace for sterilising with ozone and packing before distribution. There is no need to wash the mask before it is used for the first time.

 

In the face of the tight supply of masks amid the epidemic, the Government set aside funds to subsidise projects on technology applications of reusable masks under the first round of the Anti-epidemic Fund.

 

The CuMask complies with the American Society for Testing & Materials F2100 Level 1 standard and can be washed up to 60 times. It can also be used for a longer period after replacing the filter.

 

Mrs Lam said she is pleased to note that CuMask is well received by the public and the registration process has been very smooth.

 

“CuMask is a home-grown scientific research achievement with local application. The whole process has involved co-operation between the Government, industry, academia and the research sector and is an outstanding example of the use of technology to improve people’s lives.

 

“It will also help solve the problem of the supply of face masks during an epidemic in the long run. I highly commend all the people who have participated in the relevant work and I am fully confident in the development of innovation and technology in Hong Kong.”

 

Mrs Lam appealed to the public to make use of the registration quota of up to six people to minimise delivery resources and enhance efficiency.

 

She added that relevant departments will deliver the masks as soon as possible.

COVID-19 patient tests positive again

A recovered COVID-19 patient has tested positive for the virus again, the Hospital Authority announced today.

 

The authority’s Chief Manager (Quality & Standards) Dr Lau Ka-hin told a media briefing this afternoon that the patient was first admitted to Queen Mary Hospital on March 24 after having fever for a week. He subsequently tested positive for COVID-19.

 

He was discharged on April 16 after two consecutive negative tests for the virus.

 

Dr Lau said: "The patient presented to the Accident & Emergency Department of Queen Mary Hospital on May 5 because of some abdominal pain and diarrhoea.

 

"He was admitted to our hospital and was found to have a positive result for COVID-19 in the throat saliva, but the cycle threshold value is very high - nearly 36.

 

"The experts consider that this is the residual virus left in the patient’s body, which is not infective, and it is not likely to be a reinfection at this moment."

 

He added that the patient is in a stable condition.

Hospital discharge criteria explained

(To watch the full press briefing with sign language interpretation, click here.)

 

The Centre for Health Protection today said recovered COVID-19 patients or those who did not have any symptoms may be discharged from hospital 10 days after the onset of symptoms or a positive test result.

 

Its Communicable Disease Branch Head Dr Chuang Shuk-kwan told a press briefing that the revised discharge criteria was based on the latest scientific evidence.

 

“Our Scientific Committee on Emerging & Zoonotic Diseases met yesterday and examined the latest scientific evidence on whether the virus will be viable from a patient.

 

“And the available evidence showed that this virus is usually not detected after 10 days since the onset of symptoms of patients. Some patients may have persistent positive PCR (polymerase chain reaction) for a long period of time.”

 

Dr Chuang noted that patients still had to meet the criteria of having two clinical specimens test negative, or testing positive for the SARS-CoV-2 antibody to be discharged.

 

“We have revised the discharge criteria to include the patient who (must have) been staying in the hospital for at least 10 days after the onset of symptoms. So this is the additional criteria, in addition to the previous criteria of two consecutive negative specimens.

 

“We added another criteria (which is) in case a patient has stayed in the hospital for a long time, more than 10 days since the onset of symptoms, but he or she has persistent positive PCR despite the Ct (cycle threshold) value being very high, they can check their serology, the antibody. So if the antibody turns positive, usually it is after 10 days, then he or she can be discharged.

 

“So this is based on the latest scientific evidence.”
