The 'closed-loop system' operating around the Beijing 2022 Winter Olympics - essentially, a giant 'bio-secure bubble' - begins operating today, with a month to go until the start of the Games.

The system will allow travellers from overseas to enter China without quarantine in order to take part in the Games. All participants and staff at the Games will stay within a controlled bubble covering all Olympic venues in Beijing and the mountain venues at Yanqing and Zhangjiakou. They will remain separated from the rest of the Chinese population throughout the event. After the Games is over, overseas arrivals will fly home immediately and local staff will have to complete a 21-day quarantine before exiting the loop.
