China will stop requiring inbound travellers to go into quarantine starting from January 8, the National Health Commission said on Monday in a major step towards easing curbs on its borders, which have been largely shut since 2020.

China's management of Covid-19 will also be downgraded to the less strict Category B from the current top-level Category A, the health authority said in a statement, as the disease has become less virulent and will gradually evolve into a common respiratory infection.

The latest announcement comes after mainland authorities dropped nearly all of its domestic Covid curbs, though strict requirements on inbound travellers had remained in place, including five days of mandatory quarantine at a government-supervised facility and three more of isolation at home.

That restriction and one on the number of passengers on international flights will be removed from January 8. Travellers entering mainland China will still have to undergo PCR testing 48 hours before departure, however, the health authority said.

Arrangements for foreigners to come to China, such as for work and business will be improved and the necessary visas will also be facilitated, the authority said.

But passenger entry and exit at sea and land ports will gradually resume, while the outbound travel of Chinese nationals will be restored "in an orderly manner", it added.

Since January 2020, China had classified Covid-19 as a Category B infectious disease but managed it under Category A protocols that cover diseases such as bubonic plague and cholera, giving local authorities the power to quarantine patients and their close contacts and lock down regions.

While China downgrades its management of the new coronavirus, the National Health Commission said epidemic prevention and control protocols at key institutions such as elderly care institutions will be strengthened.

If an outbreak becomes severe, the institution will adopt so-called "closed management" to prevent the spread of infections, the authority said.

China will also further increase the vaccination rate among the elderly, and promote second doses among people at high risk of severe illness. (Reuters)
