Beijing expresses concern over US flights

The Ministry of National Defense expressed its opposition to frequent and close-in US reconnaissance of China on Monday.

The comments followed a top US navy admiral's joining a seven-hour-long surveillance flight over the South China Sea over the weekend.

US aircraft have conducted frequent reconnaissance flights near China for some time, which has gravely undermined Sino-US trust and China's security interests, and is highly likely to cause maritime and airborne incidents, the ministry's press office said.
