Authorities said that both Chinese and foreign passengers have to complete the tests within five days before embarking.
In a joint statement with the General Administration of Customs and the Ministry of Foreign Affairs, it was explained that the decision "helps reduce health risks in cross-border flows of people as well as the resumption of work in countries concerned."

The statement emphasized that tests should be conducted at institutions designated or approved by Chinese embassies.
As of today, 11 new cases were reported in the country, eight local and three from abroad. No further deaths were registered nor contagions in the capital of Beijing. Only Xinjiang reported local infections.
"Requiring a certificate for foreign travelers before boarding their plains will help to ensure a safe and utter restoration of international travel for people exchanges and economic activities," said a spokesperson from the Ministry of Foreign Affairs.
