China says US visitors will need negative virus-test results

China will require passengers arriving on direct flights from the US to provide negative Covid-19 nucleic-acid test results taken within 72 hours of the flight. Passengers traveling from the US to China, and those transiting in any country that the Chinese government has listed as requiring the screening, must have negative Covid-19 results from a test done within three days of boarding at the last layover destination, China’s embassy in America said in a statement on Friday. Both sets of rules will take effect Sept. 15. Passengers who transit in the US before flying to China will be required to submit a health declaration to the airlines or hold a green health code, according to the statement. China’s new requirement is the latest in a series of restrictions imposed on US citizens by Beijing, and counter measures taken by Washington, because of the pandemic and a deterioration in relations between the world’s two biggest economies.<br/>
