China, Russia begin live-fire naval exercises in South China Sea

China and Russia have begun live-fire naval exercises in the South China Sea, Russian and Chinese state media reported, with the two countries having strengthened military and trade ties in recent years following US sanctions on both.

The opening ceremony of the Russian-Chinese naval exercise 'Maritime Cooperation - 2024' took place in the Chinese port of Zhanjiang, the Russian defence ministry said on the Telegram messaging app.

During their sea manoeuvres, the crews of ships of the Russian Pacific Fleet and the PLA Navy were to conduct joint air defence exercises and anti-submarine drills with the involvement of PLA naval anti-submarine aviation, the Russian defence ministry said.

Both countries were to deploy at least three vessels each for the three-day exercises, China's state controlled Global Times newspaper said, citing the People's Liberation Army Navy.

Russia's RIA state news agency reported on Tuesday, citing Russia's Pacific Fleet, that the Russian Navy and the Chinese Navy conducted artillery firing as part of the joint drills.

The drills follow the completion of a separate joint naval patrol in the north Pacific, which the Russian defence ministry said earlier involved a detachment of Russia's Pacific Fleet ships, including two corvettes, the Rezky and the Gromky.

Wang Guangzheng of the PLA Navy's Southern Theatre told Chinese state broadcaster CCTV that: "the China-Russia joint patrol has promoted the deepening and practical cooperation between the two in multiple directions and fields."

"And effectively enhanced the ability to the two sides to jointly respond to maritime security threats."

Control over entire South China Sea

The participating vessels set off from a naval port in Zhanjiang in southern China's Guangdong province on Monday, the report added, citing a PLA Navy statement.

The report did not specify where in the contested waterway the drills would take place.

China claims control over almost the entire South China Sea, including the disputed Second Thomas Shoal, where the Philippines maintains a rusty warship that it deliberately grounded in 1999 to reinforce its maritime claims and which has been central to a recent standoff between the two countries.

The rising tensions have led US officials to remind Beijing that their mutual defence treat obligations with the Philippines are ironclad.

China and Russia declared a "no limits" partnership in 2022 when President Vladimir Putin visited Beijing just days before he sent thousands of troops into Ukraine. China has still not condemned the invasion and has stepped up its exports to Russia, helping Moscow keep its war economy afloat.

The "no limits" partnership saw two-way trade hit a record of $240.1 billion in 2023, up 26.3 percent from a year earlier, according to Chinese customs data.

Meanwhile, China-US trade fell 11.6 percent last year to $664.5 billion, Chinese customs data shows.
