The navies of Iran, Russia and China will hold military drills off the coast of Iran this week in a bid to boost cooperation, Iranian media reported on Sunday.

The three countries, which share a common desire to counter what they characterise as American hegemony, have held similar exercises in the region in recent years.

Azerbaijan, South Africa, Oman, Kazakhstan, Pakistan, Qatar, Iraq, the United Arab Emirates and Sri Lanka will attend as observers.

The drills “will begin on Tuesday in the port of Chabahar”, located in southeast Iran on the Gulf of Oman, the Tasnim news agency said, without specifying their duration.

“Warships and combat and support vessels of the Chinese and Russian naval forces, as well as the warships of Iran’s naval forces of the army and the Revolutionary Guards” are expected to participate, according to Tasnim.

The exercises will take place “in the northern Indian Ocean” and aim to “strengthen security in the region, and expand multilateral cooperation between participating countries”, Tasnim said.

Russia’s defence ministry said in a statement that Moscow would be represented by two corvettes and a tanker from the Pacific Fleet.

“During several days in the northern part of the Indian Ocean, the crews will work out the tasks of liberation of captured ships, search and rescue at sea as well as conduct artillery firing at sea and air targets,” the statement added.

China will deploy “a destroyer and a supply ship”, Beijing’s defence ministry said on the WeChat social media network.

The Iranian army conducted drills in the same area in February to “strengthen defence capabilities against any threat”.
