Three commercial vessels, two of which face United States sanctions, navigated the Strait of Hormuz on Tuesday, the first full day of a new US blockade targeting ships bound for Iranian ports. The move by Washington to restrict access to Iran’s maritime trade routes significantly increases the risk of regional escalation, according to Al Jazeera’s Malik Traina. One tanker was carrying 250,000 barrels of methanol.
The Panama-flagged vessel Peace Gulf, a medium-range tanker, proceeded towards Hamriyah port in the United Arab Emirates. Shipping data from LSEG indicated its course. This particular ship frequently transports Iranian naphtha, a petrochemical feedstock, to various non-Iranian ports across the Middle East for onward shipment to Asian markets, Kpler data revealed.
Its transit Tuesday was not impacted by the newly imposed restrictions, as its destination lay outside Iranian territorial waters. Before the Peace Gulf’s passage, two tankers already under US sanctions had traversed the narrow waterway. This strait accounts for one-fifth of global energy exports.
The handy tanker Murlikishan, previously known as MKA, is scheduled to load fuel oil in Iraq on Thursday, according to Kpler data. It has a history of moving both Russian and Iranian oil. Another sanctioned tanker, the Rich Starry, marked a significant transit.
It became the first vessel of its kind to successfully exit the Gulf through the strait since the blockade began on Monday, data from LSEG and Kpler showed. The tanker and its owner, Shanghai Xuanrun Shipping Co Ltd, faced US sanctions for their dealings with Iran. The Rich Starry, a medium-range tanker, carried approximately 250,000 barrels of methanol.
It had loaded its cargo at its last port of call, Hamriyah. A Chinese crew manned the Chinese-owned vessel. These movements underscore the immediate complexities facing shipping operations in the region.
United States President Donald Trump announced the port blockade on Sunday. This decision followed the collapse of weekend peace talks between the US and Iran in Islamabad, Pakistan. The negotiations had aimed to de-escalate tensions that have gripped the Gulf region for months.
Prior to Trump’s announcement, Iran had itself imposed a near-total halt on traffic through the Strait of Hormuz. This action came in response to a series of US-Israeli attacks on Iranian territory, which began on February 28. Tehran’s effective control over the critical chokepoint had sent global gas and petrol prices soaring.
Washington's current strategy directly aims to diminish Tehran’s influence over the strait. The intent is to prevent Iranian tankers, which had continued daily transits, from passing through the strategic passage. This represents a direct challenge to Iran's previous leverage. "This complicates everything for commercial vessels that have been stranded in the Gulf," stated Malik Traina, reporting from Kuwait City for Al Jazeera. "They now have to get permission from Iran to pass through, as well as the US." His words highlight the dual authority now asserted over the strait.
Traina further warned of the potential for conflict. "There’s a real risk of escalation here," he said. "If Iranian vessels are stopped, if Iranian oil is stopped, Iran could perhaps stop other vessels from the Gulf coming and entering the strait." This scenario presents a clear danger to global shipping. China, a major player in regional trade, voiced strong objections. Chinese Ministry of Foreign Affairs spokesman Guo Jiakun said Tuesday that the US had "increased military operations and took a targeted blockade action, which will only exacerbate tensions and undermine the already fragile ceasefire agreement." He did not mince words.
Guo described the US action as "dangerous and irresponsible behaviour." He added that it "further jeopardises safety of passage through the strait." Beijing relies heavily on Middle Eastern energy. More than half of China’s oil imports originate from the Middle East, with Iran being a particularly significant supplier. Kpler data indicates that China purchased over 80 percent of Iran’s shipped oil last year.
This translates to 1.4 million barrels of Iranian crude oil per day, out of China’s total 10.4 million barrels of seaborne crude imports daily. Such dependence makes China's stance unsurprising. Despite the new blockade, the possibility of a diplomatic resolution has not entirely faded.
President Trump indicated that Iran still has an opportunity to reach an agreement. A Pakistani official, speaking to Al Jazeera, confirmed the country's readiness to host further rounds of peace talks for as long as necessary. Diplomatic contact between all parties involved continues, offering a glimmer of hope.
These ongoing discussions provide a counterpoint to the escalating military and economic pressures. The international community watches closely. Why It Matters: The US blockade of Iranian ports and the subsequent movements in the Strait of Hormuz directly impact global energy markets and international trade.
Disruptions to this vital maritime choke point, which sees billions of dollars in oil and gas transit daily, can trigger immediate price spikes for consumers worldwide. Furthermore, the actions raise the specter of military confrontation in an already volatile region, threatening broader stability and potentially drawing in major global powers with economic interests at stake. The safety of commercial shipping is now under scrutiny. - The US initiated a blockade on Iranian ports following failed peace talks, aiming to curb Iran's maritime trade. - Three vessels, including two under US sanctions, transited the Strait of Hormuz on Tuesday, with none heading to Iranian ports. - China strongly condemned the US blockade, citing its significant reliance on Iranian oil and concerns over regional escalation. - Diplomatic channels remain open, with Pakistan offering to host further talks despite the increased tensions.
All eyes will remain on the Strait of Hormuz for further shipping activity and any direct confrontations between US and Iranian forces. Observers will also monitor global oil and gas prices for volatility. The willingness of Pakistan to continue mediating suggests that diplomatic efforts, however strained, may yet resume.
The next few days will test the resolve of both Washington and Tehran, and determine whether the blockade will lead to a broader regional crisis or force a return to the negotiating table. Any stoppage of Iranian tankers could quickly escalate.
