The Civil Aviation Administration of China (CAAC) has banned Bangladesh's US-Bangla Airlines (BS, Dhaka) from operating its only Chinese route, to Guangzhou, after five passengers on a June 27 flight tested positive for COVID-19.

The ban is valid for one week and started on July 6, 2020. Since US-Bangla Airways flies between Dhaka and Guangzhou only 1x weekly, CAAC's decision will impact just a single rotation.

According to rules in place since early June, the CAAC automatically bans for a week any carrier which registers more than five COVID-positive passengers during a single flight. If the number of infected passengers exceeds 10, the ban is valid for four weeks. US-Bangla Airlines is the first foreign airline affected by the rule.

The Bangladeshi carrier operates the Guangzhou route using B737-800s and last flew on July 4-5, Flightradar24 ADS-B data shows.
