COSCO Shipping's Yuan Gui Yang. The vessel is the group's last very large crude carrier (VLCC) to sail out of the Strait of Hormuz.

Two Chinese very large crude carriers (VLCCs) sailed out of the Strait of Hormuz on the morning of May 20, easing a weeks-long bottleneck for vessels trapped in the Persian Gulf after Iran closed the critical oil chokepoint.

The two 300,000-ton-capacity ships departed an anchorage off Dubai on May 19. Unlike other Chinese vessels that recently navigated the tense waterway, neither ship broadcast the “CHINESE OWNER & CREW” identity tag on their tracking systems while transiting the strait.
