China and Russia have launched what is being called their largest joint military maneuvers in three decades, a massive exercise that stretches from the Arctic Ocean to the Mediterranean. Russian President Vladimir Putin made it clear that the primary point is to send a message to the US.

According to the Russian Defense Ministry, the drills involve more than 90,000 troops, more than 400 warships and submarines and over 120 planes and helicopters. The two navies will also cruise together in the Pacific, the fifth time that has happened.

“We pay special attention to strengthening military cooperation with friendly states,” Putin said. “Today, in the context of growing geopolitical tensions in the world, this is especially important.

“Under the pretext of countering the allegedly existing Russian threat and containing the People’s Republic of China, the United States and its satellites are increasing their military presence near Russia’s western borders, in the Arctic and in the Asia-Pacific region…Russia must be prepared for any development of the situation.”

In July, the Russian and Chinese navies conducted six days of live-fire exercises off China’s Guangdong province. At that time, unnamed experts quoted in the Global Times, the English-language newspaper controlled by China’s Communist party, said that “unlike the US that aims to maintain its global military hegemony, the China-Russia military cooperation provides stabilizing factors to the deteriorating global and regional security.”
