The move comes after similar announcements by India, Italy, Taiwan and the US.

Travellers from China will be required to provide a negative PCR test within 48 hours of departure or a rapid antigen test taken within 24 hours, followed by a PCR test after arrival, Prime Minister Han Duck-soo said on Friday.

South Korea will also temporarily halt the expansion of flights to China and limit all internal flights to Incheon International Airport, the country’s biggest, Han said.

“We need to urgently prepare for any domestic ripple effects following China’s easing of quarantine rules,” Han said. “We will prepare to take stronger measures in case the situation gets worse, if we see a rapid increase of infections from new arrivals or appearance of new variants.”

The measures come after India, Italy, Taiwan and the United States introduced COVID tests for arrivals from China amid concerns about the potential emergence of new variants and the Chinese government’s lack of transparency. Other countries, including the Philippines and the United Kingdom, are considering similar measures.

Some health experts have questioned the need for the restrictions, arguing they are unlikely to stop the spread of new virus variants.

European Union officials on Thursday rejected a call from Italian Prime Minister Giorgia Meloni for the bloc to test all air passengers from China.

Infections have surged in China following Beijing’s decision to unwind its controversial “zero-COVID” policy, putting hospitals, morgues and crematoriums under strain.

Chinese authorities have been accused of downplaying the seriousness of the situation, with health officials reporting only a handful of deaths in recent weeks.

Health experts have predicted China could experience up to 2 million deaths in the coming months due to the population’s lack of natural immunity after nearly three years of isolation and patchy vaccine uptake among the elderly.
