At a time when the US and Saudi Arabia have been stepping up efforts to isolate Iran, China is doubling down on support for its regional ally.

Chinese and Iranian destroyers are conducting a joint military drill in the eastern portion of the Strait of Hormuz and Sea of Oman, reports Reuters, citing the Islamist Republic News Agency.

The US navy has recently accused Iran of sending vessels to harass warships passing through the Strait of Hormuz.
