China has been relaxing a ban on most foreign travellers that was imposed in March to prevent an influx of infections after authorities largely brought the domestic epidemic under control.
But under new regulations announced Tuesday by the Civil Aviation Administration of China citizens must now also upload a picture of their negative test certificate to a health app, while foreigners must apply to a Chinese embassy or consulate with proof of their status.China has reported more than 80,000 infections and 4,634 deaths since COVID-19 first emerged in the central city of Wuhan late last year.
In recent months China has allowed some foreign diplomats, employees of large enterprises and other business travellers back into the country on specially chartered flights.
