Shenzhen Bao'an International Airport resumed its regular international passenger flights on Friday after an over three-month suspension of its international flights due to the COVID-19 epidemic.

The airport suspended all the international passenger flights since the end of March in accordance with the requirements of the Civil Aviation Administration of China.

Its operation of the international flights restarted as a flight of Air Busan departing from Seoul, the Republic of Korea, arrived at the Shenzhen Bao'an International Airport on Friday.

According to the airport, Shenzhen Airlines will also resume the route between Shenzhen and Japan's Tokyo from July 26.

The airport has seen the daily flight number exceeding 1,000 in summer holiday travel rush, returning to its pre-epidemic level, and the daily maximum passenger flow hitting 130,000, 90 percent of its capacity before the epidemic.

The airport, together with the customs and airline companies, has further intensified measures against the epidemic by adopting a closed-off management for inbound passengers, including boarding inspection, temperature monitoring and epidemiological investigation, and strengthening the disinfection of the sites.
