BEIJING -- The Chinese government sharply criticized COVID-19 testing requirements imposed on visitors from China and threatened countermeasures against countries involved, which include the U.S. and several European nations.
鈥淲e believe that the entry restrictions adopted by some countries targeting China lack scientific basis, and some excessive practices are even more unacceptable,鈥 Foreign Ministry spokesperson Mao Ning said at a daily briefing Tuesday.
鈥淲e are firmly opposed to attempts to manipulate the COVID measures for political purposes and will take countermeasures based on the principle of reciprocity,鈥 she said. Mao did not specify what steps China might take.
The comments were China's sharpest to date on the issue. Australia and Canada this week joined a growing list of countries requiring travellers from China to take a COVID-19 test prior to boarding their flight, as China battles a nationwide outbreak of the coronavirus after abruptly easing restrictions that were in place for much of the pandemic.
Other countries including the U.S., India, Japan, South Korea and several European nations have announced tougher COVID-19 measures on travellers from China amid concerns over a lack of data on infections in China and fears that new variants may emerge.
China has had some of the toughest entry requirements for people arriving from abroad. It is about to drop a mandatory five-day quarantine for all arrivals but will still require a negative COVID-19 test within 48 hours of the flight.
White House press secretary Karine Jean-Pierre said 鈥渢here鈥檚 no cause for retaliation鈥 by Beijing for countries 鈥渢aking prudent health measures to protect their citizens鈥 with COVID-related restrictions on travellers coming from China. She added that restrictions were 鈥渂ased on public health and science.鈥
鈥淭his is something that all of us, (and) other countries are doing to make sure that we are protecting our citizens here,鈥 Jean-Pierre said.
French Prime Minister Elisabeth Borne defended the tests. Starting Wednesday, anyone flying from China to France will have to present a negative virus test taken within the previous 48 hours and be subject to random testing on arrival.
鈥淲e are in our role, my government is in its role, protecting the French,鈥 Borne said Tuesday on France-Info radio.
The U.K. will require that passengers from China take a COVID test before boarding the plane from Thursday. Transport Secretary Mark Harper said the requirement is for 鈥渃ollecting information鈥 because Beijing isn't sharing coronavirus data.
Health officials will test a sample of passengers when they arrive in the U.K., but no quarantine is required for those who test positive, he said.
鈥淭he policy for arrivals from China is primarily about collecting information that the Chinese government is not sharing with the international community,鈥 Harper told the LBC radio station on Tuesday.
Sweden鈥檚 Public Health Agency said Tuesday that it had urged the government to require travellers from China to present a recent negative COVID-19 test.
The statement from the agency comes as Sweden, which has taken over EU鈥檚 rotating presidency, has called a meeting of the EU鈥檚 crisis management mechanism for Wednesday to try to agree on a common European line.
The Swedish government 鈥渋s preparing to be able to introduce travel restrictions. At the same time, we are conducting a dialogue with our European colleagues to get the same rules as possible in the EU,鈥 Justice Minister Gunnar Strömmer said in a statement.
Austria, too, plans to test the wastewater of all planes arriving from China for new variants of the coronavirus, the Austria Press Agency reported Tuesday, following a similar announcement by Belgium a day earlier.
Chinese health officials said last week that they had submitted data to GISAID, a global platform for sharing coronavirus data.
The versions of the virus fuelling infections in China 鈥渃losely resemble鈥 those that have been seen in different parts of the world between July and December, GISAID said Monday.
Dr. Gagandeep Kang, who studies viruses in the Christian Medical College of Vellore in India, said that the information from China, albeit limited, seemed to suggest that 鈥渢he pattern was holding鈥 and that there wasn鈥檛 any sign of a worrisome variant emerging.
Mi Feng, the spokesperson for China鈥檚 National Health Commission, said authorities have been open and transparent since the start of the pandemic three years ago. China held technical exchange meetings twice with the WHO last month on the overall situation, medical treatment, vaccination and other issues, he said Tuesday.
A senior Hong Kong official also criticized the steps taken by some other countries. Some have applied the requirements to passengers from Hong Kong and Macao, both semiautonomous Chinese territories, as well as mainland China.
Hong Kong Chief Secretary Eric Chan said in a Facebook post that the government had written to various consulates on Monday to express its concerns over the 鈥渦nnecessary and inappropriate鈥 rules.
Some experts have questioned the effectiveness of the testing. Kerry Bowman, assistant professor at the University of Toronto鈥檚 Temerty Faculty of Medicine, said that people can test positive long after entering the country.
The requirement is 鈥渘ot based on science at this point,鈥 he said after Canada announced measures last weekend.
China, which for most of the pandemic adopted a 鈥渮ero-COVID鈥 strategy that imposed harsh restrictions aimed at stamping out the virus, abruptly eased those measures in December.
Chinese authorities previously said that from Jan. 8, overseas travellers would no longer need to quarantine upon arriving in China, paving the way for Chinese residents to travel.
