BEIJING - 皇冠体育app's military rejected US claims on 皇冠体育app's "unsafe" intercept of an American Navy reconnaissance aircraft over the South 皇冠体育app Sea, and demanded the US ends such action.

Yang Yujun, spokesman of the Ministry of National Defense, told a press conference that 皇冠体育app's aircraft acted professionally and in line with a 皇冠体育app-US encounter safety code agreed by both sides.

Yang said America's frequent reconnaissance over Chinese waters is a real source of danger for 皇冠体育app-US military safety.

Yang said the agreement only provides a technical regulation, and the best solution was for the US to stop such action.

The Pentagon claimed two Chinese J-11 fighters unsafely intercepted a US EP-3 Aries aircraft on May 17 which was conducting routine operations in international airspace.
