Chinese and Russian navies will conduct a joint exercise in the East China Sea, according to a spokesman for the People's Liberation Army navy.

Senior Captain Liang Yang said in Beijing on Tuesday that 14 ships, two submarines, nine fixed-wing aircraft and several helicopters from the two navies will take part in the drill, which will begin on May 20 and last seven days.

The drill will test the two parties' capabilities to launch joint operations such as anti-ship strikes, anti-submarine combat and the rescue of hijacked vessels.

The act aims to strengthen coordination between China and Russia in maritime operations and is not directed against any third party, according to him.
