Russia, China join forces for major naval exercise

Russian and Chinese warships began joint drills in the Sea of Japan on Tuesday, part of a major naval exercise that President Vladimir Putin said was the largest of its kind for three decades.

Moscow and Beijing have deepened military and economic cooperation in recent years, as both countries seek to counterbalance what they see as a United States-led global order.

Russia's Ocean-2024 exercise will take place in the Pacific and Arctic as well as the Mediterranean, Caspian and Baltic Seas and is the first of its type "in the last three decades", Putin said in a televised address.

"Under the pretext of countering the alleged Russian threat and containing the People's Republic of China, the US and its satellites are increasing their military presence near Russia's western borders, in the Arctic and in the Asia-Pacific region," Putin said.

"Russia must be prepared for any development of the situation," he added.

He said the drills were aimed at testing the "combat readiness" of Russia's military leadership, without elaborating.

The drills will involve more than 400 warships, submarines and support vessels and last until 16 September, according to the Russian defence ministry.

China sent four warships and a supply vessel to the exercise, joining Russia's naval fleet in the Sea of Japan, it said. Also taking part are "more than 120 aircraft and helicopters ... about 7,000 units of weapons, military and special equipment, and more than 90,000 personnel," the ministry added.

The Japanese defence ministry said it had observed five Chinese naval ships entering the Sea of Japan heading in the direction of Russia over the weekend.

It "confirmed that these vessels sailed north-eastwards through the Tsushima Strait towards the Sea of Japan from Saturday to Sunday". Japan's Self-Defence Forces "conducted vigilance monitoring and intelligence gathering" with a vessel and patrol plane, the ministry said, releasing photos of the ships.
