China Replaces PCR Test with Antigen Test for Inbound Travelers.

China has announced that it will no longer require inbound travelers to show a negative PCR test for Covid-19, but it is unclear whether testing requirements will be abolished altogether. Instead, travelers can take an antigen test to replace the previously mandated PCR test within 48 hours before boarding their flight. Airlines will not check test results before boarding, and customs officials will conduct unspecified spot checks. China has insisted that its Covid measures were driven purely by science and will continue to scientifically optimize its rules.
