China conducts intensive anti-submarine exercises amid South China Sea tensions

China’s military has recently conducted extensive anti-submarine exercises in the strategically significant South China Sea. This initiative aims to enhance its capabilities amidst escalating maritime tensions with neighbouring countries and their allies. In an undisclosed South China Sea area, the Southern Command Theatre of China’s People’s Liberation Army reported that over a dozen anti-submarine patrol aircraft executed uninterrupted operations for over 40 hours. “It has effectively honed the military’s round-the-clock aerial anti-submarine combat capabilities,” said the statement. The exercise was conducted late at night and in the early morning to accumulate experience at different hours. The statement did not say whether any non-Chinese submarines were identified in the area. It was one of several such drills this year and was part of broader activities the Chinese military has conducted in the Indo-Pacific region. The United States and its allies have also stepped up military activities, especially in the South China Sea, most of which is claimed by Beijing. Last week, the U.S. and Indonesian defence chiefs said China’s territorial claims in the South China Sea were “inconsistent with international law”. The U.S. Navy added that China’s “aggressive behaviour” in the area, including the use of water cannons against a Philippine vessel, must be challenged and checked. The largest of the U.S. Navy’s forward-deployed fleets, the Seventh Fleet, headquartered in Japan, operates as many as 70 ships, and has about 150 aircraft and more than 27,000 sailors. The U.S. Navy also operates about two dozen nuclear-powered attack subs across the Pacific. The nuclear submarine capability of U.S. allies in the region will be further enhanced in coming years with the AUKUS agreement between the United States, Australia and Britain. “Japan and the United States have frequent submarine activities in the region,” said Chinese military commentator Song Zhongping, but those activities were not disclosed.
