China said it will ease coronavirus restrictions to allow more foreign carriers to fly to the mainland, shortly after Washington vowed to bar Chinese airlines from flying to the United States due to Beijing's curbs on American airlines.

The Civil Aviation Administration of China (CAAC) said in a statement on Thursday that qualifying foreign carriers currently barred from operating flights to mainland China will be allowed once-per-week flights into a city of their choosing starting June 8.

Hong Kong and Macau, though part of China, have their own aviation authorities and set their own rules.
