A Chinese naval flotilla set off on Sunday to join Russian naval and air forces in the Sea of Japan in an exercise aimed at “safeguarding the security of strategic waterways”, according to China’s defence ministry.

Codenamed “Northern/Interaction-2023”, the drill marks enhanced military cooperation between China and Russia since Moscow’s invasion of Ukraine and is taking place as Beijing continues to rebuff US calls to resume military communication.

The Chinese flotilla comprised of five warships and four ship-borne helicopters, left the eastern port of Qingdao and will rendezvous with Russian forces in a “predetermined area”, the ministry said on its official WeChat account on Sunday.

On Saturday, the ministry said Russian naval and air forces would participate in the drill taking place in the Sea of Japan.

This would be the first time both Russian forces take part in the drill, state newspaper Global Times cited military observers as saying.

Gromkiy and Sovershenniy, two Russian warships taking part in the Sea of Japan drill, had earlier this month conducted separate training with the Chinese navy in Shanghai on formation movements, communication and sea rescues.

Before making port at the financial hub of Shanghai, the same ships had sailed passed Taiwan and Japan, prompting both Taipei and Tokyo to monitor the Russian warships.
