China plans to require all passengers on direct flights from South Korea to undergo a PCR test upon arrival, starting from Feb. 1, the South Korean embassy in Beijing said. Chinese foreign ministry spokeswoman Mao Ning said, “It is regrettable that individual countries persist on implementing discriminatory entry restrictions against China, to which China is firmly opposed and has reason to take reciprocal measures against.” (https://neuters.de/world/asia-pacific/skorea-considers-early-easing-covid-visa-curbs-travellers-china-yonhap-2023-01-31/) She was responding to a query about China mandating COVID test for inbound travellers from South Korea. South Korea’s foreign ministry said its quarantine measures were based on scientific grounds for people’s protection. “There should never be any restrictions based on factors other than quarantine, and we are also communicating with the Chinese side as necessary,” the ministry added in the transcript of a news briefing. The curbs have hit air traffic links, one airline official said.
