Three Iran-linked tankers entered the Persian Gulf on Tuesday. They passed through the Strait of Hormuz. This Persian Gulf transit happened on the first day of a new U.S. blockade. The blockade specifically targets vessels that call at Iranian ports.
This Persian Gulf transit consequently shows the difficulty of enforcing the U.S. measure. U.S. President Donald Trump announced the blockade on Sunday. Peace talks between Washington and Tehran had just failed in Islamabad. Neither side however reached any agreement.
Shipping data indeed confirms the three vessels moved without immediate interference. One tanker for example is the Peace Gulf. It flies a Panama flag. This medium range tanker instead sails to Hamriyah port in the United Arab Emirates. This vessel usually carries Iranian naphtha. Naphtha in fact is a petrochemical feedstock. The ship then moves this product to non-Iranian ports in West Asia. From there shipments subsequently continue to Asia.
Two other U.S.-sanctioned vessels similarly made the Persian Gulf transit. The first namely is the Murlikishan. This Handy size tanker currently heads toward Iraq. It plans to load fuel oil on April 16. This ship previously carried both Russian and Iranian crude. The second vessel meanwhile is the Rich Starry. This tanker carries roughly 250,000 barrels of methanol. It loaded this cargo at Hamriyah in the UAE. The Rich Starry furthermore is Chinese-owned. Chinese nationals also crew the vessel. Its owner Shanghai Xuanrun Shipping Co. Ltd. accordingly faces US sanctions for dealing with Iran.
China’s foreign ministry quickly criticized the U.S. blockade on Tuesday. Officials called the move dangerous and irresponsible. They warned it would raise regional tensions. Beijing however did not say if any Chinese vessels now cross the strait.
The Strait of Hormuz nevertheless remains a critical waterway. Nearly one-fifth of global oil passes through it. Any sustained blockade could therefore easily disrupt energy markets. Analysts note that previous US naval pressure campaigns had mixed results. Iran for its part has often used small boats and diplomatic maneuvers to keep shipments moving.
Future outlooks still remain quite uncertain. The U.S. has not yet deployed additional warships to enforce the blockade. Iran has similarly not announced any direct countermeasures. Meanwhile buyers in Asia continue to receive Iranian petrochemicals. They frequently use transshipment points in the UAE and Iraq. This latest Persian Gulf transit consequently suggests the blockade faces major enforcement gaps. Next steps may ultimately include more U.S. sanctions on shipping intermediaries or Chinese firms. For now however tanker traffic continues almost normally.
