China’s anti-spy agency flags security risk from open window shades at dual-use airports
- Warning issued in reference to a recent case involving a foreign national, Ministry of State Security says on WeChat but gives no further details

In an article posted on its official WeChat account, the ministry said such joint-use facilities, which make up nearly one-third of China’s airports, usually deploy important military equipment and passengers are not permitted to take photos of the sensitive military areas.
These airports are used for both civil aviation and regular air force training, and will be available for military use during wartime, the ministry said. Also, many of them are located near coastal and border areas “holding prominent strategic positions and significant military value”, it noted.
According to domestic media reports, a foreign national on board a flight from the eastern Chinese city Yiwu to Beijing earlier this month allegedly used their phone to take photos of a joint-use airport, and a fellow passenger reported the issue.
