Beijing's municipal government has announced tightened quarantine rules targeting international arrivals, amid a growing number of imported cases in the Chinese capital.
Starting immediately, anyone arriving in Beijing from overseas will be required to self-quarantine at home or designated facilities for 14 days. Previously, only people arriving from "high-risk" regions were mandated to do so.
International business travelers can only stay at designated hotels in Beijing and have to be tested for the coronavirus. They are not allowed to leave their hotels before receiving test results.
The city has cordoned off a wing of Terminal 3 at its massive Capital International Airport to screen and register all international arrivals.
The authorities have also set up a transportation hub at an exhibition center near the airport, deploying a dedicated fleet of cars to drive arriving passengers to their homes or facilities for medical observation.
Beijing's Capital airport is the world's second busiest, with more than 100 million travelers passing through its three terminals last year, of which more than 26 million were international passengers.
On Tuesday, Beijing reported six new confirmed cases of the coronavirus, all of which were imported cases, including five from Italy and one from the United States.
