Chinese Premier Li Keqiang on Thursday urged provinces to adjust their prevention measures and focus more on cross-border transition as the domestic situation for COVID-19 outbreak continues to ease.

Noting that the number of domestic transition cases reduced to zero on Wednesday, for the first time since the outbreak, Li instructed government at all levels to ease unreasonable restrictions that hinder the resumption of work so more people can return to work and get their incomes as soon as possible.

Given the pandemic status of COVID-19, Li instructed that more efforts should be put on the prevention of cross-border transmission.

A National Health Commission official said at a press conference on Thursday that imported coronavirus cases accounted for 84.55 percent of the new confirmed cases in China in recent weeks.

As of midnight Wednesday, Beijing has reported a total of 64 imported COVID-19 cases, the most in the country, accounting for 34 percent of the total imported cases of COVID-19 nationwide, according to Pang Xinghuo, deputy director of the municipal center for disease prevention and control, on Thursday.

For measures to prevent cross-border transmission, Li called for enhanced health checks for international flights that come from severely infected regions, and comprehensive prevention and control measures for both Chinese and foreign nationals arriving in China.

The Civil Aviation Administration of China (CAAC) announced on the same day that it would divert some international flights originally bound for Beijing to other Chinese cities such as Tianjin, Hohhot, and Taiyuan, as an epidemic prevention and control measure. Some of the flights include Air China's CA 910 from Moscow, CA 934 from Paris, CA 926 from Tokyo, and Hainan Airlines' HU 7976 from Toronto.

While suggesting the reduction of unnecessary outbound activities, the Premier urged governments to protect the health and personal safety of citizens abroad with necessary assistance and support.
