Foreigners with valid visas issued before March 28, 2020 will be allowed to enter China, as the country is adjusting its visa and entry policies to facilitate travel across the border.

Visa-free policies will be resumed for entry to the southern island province of Hainan and cruise tour groups at Shanghai ports, said the National Immigration Administration.

Visa-free entry to the southern province of Guangdong will be restored for tour groups of foreigners from Hong Kong and Macao, and a similar mechanism will be reinstated for tour groups from ASEAN countries to enter Guilin in the southern Guangxi Zhuang Autonomous Region.

The policies will come into force on Wednesday, according to immigration authorities.
