Iran, China and Russia started four days of joint naval drills in the Indian Ocean and the Gulf of Oman on Friday, the commander of Iran’s flotilla announced.
The exercise comes at a time of heightened tensions since the United States withdrew from a landmark 2015 nuclear deal with Iran in May last year.
“The message of this exercise is peace, friendship and lasting security through cooperation and unity… and its effect will be to show that Iran cannot be isolated,” Rear Admiral Gholamreza Tahani said on state television.
RAdm Tahani added that the drills included rescuing ships on fire or vessels under attack by pirates and shooting exercises, with both Iran’s navy and its Revolutionary Guards participating.
State television showed what it said was a Russian warship arriving at Chabahar port in southern Iran and said the Chinese will join shortly, calling the three countries “the new triangle of power in the sea”.
“The aim of this drill is to bolster security of international maritime commerce, combatting piracy and terrorism and sharing information… and experience,” the flotilla commander said.
“Us hosting these powers shows that our relations have reached a meaningful point and may have an international impact,” he added.
The United States reimposed crippling sanctions on Iran after quitting the nuclear deal last year, prompting Tehran to hit back with countermeasures by dropping nuclear commitments. Remaining parties to the badly weakened agreement include Britain, France and Germany as well as China and Russia.
In June, Donald Trump, the US president, authorised a military strike after Iran shot down a US drone, only to call off the retaliation at the last moment.
The crisis deepened with September 14 attacks on Saudi energy giant Aramco’s Abqaiq processing plant and Khurais oilfield, which halved the kingdom’s crude output.
Yemen’s Houthi rebels claimed responsibility for the attack but Washington accused Tehran, a charge it has strongly denied.
Washington has responded with a military build-up in the Gulf and has launched an operation with its allies to protect navigation in Gulf waters.
