The officials said the Biden administration was considering steps similar to those already taken by Japan, which said Tuesday that all travelers from mainland China would be tested on arrival, and Malaysia, which has stepped up tracking and surveillance of travelers from China.
Taiwan also said Wednesday that travelers from mainland China would have to take a PCR test on arrival, with those who test positive allowed to isolate at home.
Last week, India said it would make virus testing mandatory for travelers arriving from China as well as Japan, South Korea, Hong Kong and Thailand.
Any restrictions would be applied to all travelers coming from China, regardless of nationality, the U.S. officials said.
Earlier this month, China abruptly eased its “zero-Covid” approach following mass protests, scrapping domestic rules and lifting quarantine requirements for those traveling to China.
