In a significant easing of Covid controls, the Chinese government said Wednesday that people will no longer need to show negative virus tests or health codes in order to travel between different parts of the country.

Chinese authorities also said that unless an area is designated as high-risk, work and local production cannot be stopped.

The announcement on the National Health Commission’s website formalized other recent changes to Covid controls, such as allowing more people to quarantine at home.

The measures also said that other than facilities such as retirement homes, elementary and middle schools and health clinics, venues should not require negative virus tests or health code checks.
