China said it conducted air and sea drills in the South China Sea on Tuesday as it stakes an increasingly assertive claim to virtually the whole sea despite rival claims by neighbours.
China conducts air, sea drills
It did not specify where exactly the exercises took place.
The live-ammunition drills involved more than 100 ships, dozens of aircraft, information warfare units as well as the nuclear force, the state-backed China Military Online said in a report posted on the defence ministry's website.
China claims most of the potentially energy-rich South China Sea, through which $5 trillion in ship-borne trade passes every year, and rejects the rival claims of Vietnam, the Philippines, Brunei, Malaysia and Taiwan.
The United States has called on claimants to settle differences through talks and has said its Pacific Fleet aims to protect sea lanes critical to U.S. trade with Southeast Asia and the oil-rich Middle East.
China rejects U.S. involvement in the dispute and its more assertive approach recently, which has included land reclamation and construction on disputed reefs, has raised tension.
The latest exercises focused on integrating information warfare systems with air and naval forces, as well as testing the combat effectiveness of new weapons and equipment, China Military Online said.
The military achieved "new breakthroughs" in several areas including engaging high-speed low-altitude targets, anti-submarine warfare and intercepting supersonic anti-ship missiles with surface warships, it added.
The drills used "all sorts of information technology tactics" to create simulated reconnaissance, surveillance, and early warning systems to detect air and sea targets in real time, it said.
The exercises were conducted in "a complex electromagnetic environment" involving many types of missiles, torpedoes, shells and bombs, it said.
China's navy on Saturday played down its recent exercises in the South China Sea and criticised other countries for "illegally" occupying islands and reefs.
