The Chinese embassy in South Korea has suspended the issue of short-term visas for South Korean visitors, it said on Tuesday, the first retaliatory move against nations imposing COVID-19 curbs on travellers from China.
The embassy will adjust the policy subject to the lifting of South Korea's "discriminatory entry restrictions" against China, it said on its official WeChat account.
The announcement comes a day after Foreign Minister Qin Gang expressed concern about the restrictions in a telephone call with his South Korean counterpart Park Jin, according to China's foreign ministry.
