Beijing had said it would retaliate against countries that require negative tests from Chinese travellers

China has suspended issuing short-term visas in South Korea and Japan after announcing it would retaliate against countries that required negative Covid-19 tests from Chinese travellers.

China has ditched mandatory quarantines for arrivals and allowed travel to resume across its border with Hong Kong since Sunday, removing the last major restrictions under the “zero-Covid” regime that it abruptly began dismantling in early December after protests against the curbs.
