Military commanders from Russia and China are deepening their engagement with South Africa. They are taking part in joint drills in the Indian Ocean.

The Russian defense ministry announced the start of the 10-day naval exercise off the east coast of South Africa.

The Russians are sending a warship that was deployed just last month. It is armed with a missile called the Zircon that can carry nuclear warheads and travel at nine times the speed of sound.

Chinese commanders have sent three warships to take part. They include a destroyer, a frigate and a support vessel.

Leaders in South Africa have maintained a neutral stance on the war in Ukraine. However, opposition lawmakers have been critical. They say the drills send a message of support for the invasion.
