- Beijing expressed gratitude for coordination that allowed three Chinese ships.
- The two Cosco ultra-large container carriers, CSCL Indian Ocean and CSCL Arctic Ocean, exited the Gulf on Monday.
- Iran, maintaining strong ties with China, has restricted access to the strait but allows passage for “friendly countries”.
Beijing expressed “gratitude” on Tuesday for coordination that enabled three Chinese ships to transit the Strait of Hormuz, the crucial waterway which Iran has all but closed during the war in the Middle East.
Two of the vessels, belonging to state-owned shipping giant Cosco, passed through the strait while exiting the Gulf on Monday morning, data from the MarineTraffic monitor showed.
A third ship, a Hong Kong-flagged oil and chemical tanker called the Egret, crossed earlier on 25 March sailing from east to west, according to maritime analytics firm Kpler.
“Following coordination with relevant parties, three Chinese vessels recently transited the Strait of Hormuz,” foreign ministry spokesperson Mao Ning told a press conference.
“We express our gratitude to the relevant parties for the assistance provided,” she said.
She did not mention Iran or specify who was involved in coordination efforts.
Shipping through the strait has slowed to a trickle since Iran effectively blocked access following US-Israeli attacks on the country.

The two Cosco vessels – the CSCL Indian Ocean and the CSCL Arctic Ocean – are both ultra-large container carriers.
They passed close to Iran’s Larak Island and are bound for Port Klang in Malaysia.
The ships had aborted an attempt to transit on Friday, according to MarineTraffic.
Cosco declined to comment on the transits when contacted by AFP.
Iran has said the Strait of Hormuz is open to ships of “friendly countries”. It maintains healthy diplomatic ties with China.
Cosco said on Wednesday it was resuming bookings for shipments from Asia to several Gulf countries, though without using routes that transit Hormuz.
The Shanghai-based firm had suspended bookings for services through the strait earlier in March due to the war.
