China Urges Restraint After U.S. Navy Seizes Iranian Cargo Ship Near Strait of Hormuz
The United States Navy has seized an Iranian-flagged cargo ship in the Gulf of Oman after firing on its engine room. Beijing responded with concern, urging all parties to preserve the ceasefire and keep negotiations alive — but the incident has cast new doubt over the fragile peace process.

U.S. Forces Board and Seize Iranian Vessel
The situation in and around the Strait of Hormuz escalated sharply on Sunday, April 19, when the U.S. Navy intercepted and seized the Iranian-flagged cargo ship Touska in the Gulf of Oman. The vessel had reportedly attempted to bypass the American naval blockade of Iranian ports, which has been in effect since April 13.
President Donald Trump confirmed the operation on social media, stating that the guided missile destroyer USS Spruance intercepted the ship after firing on its engine room. U.S. Marines subsequently boarded and took control of the vessel. Trump noted the ship was already under U.S. Treasury sanctions for a prior history of illegal activity.
According to ABC News, this appears to be the first instance of American forces physically seizing a merchant vessel since the blockade began. Joint Chiefs Chairman General Dan Caine had previously warned that the U.S. would "actively pursue any Iranian-flagged vessel or any vessel" attempting to run the blockade.
Iran Vows Retaliation, Calls It "Piracy"
Tehran reacted with fury. Iran's military described the seizure as "armed piracy by the U.S. military" and vowed retaliation. According to Iran's state broadcaster IRIB, the military accused U.S. forces of destroying the ship's navigational equipment and deploying troops on deck — calling it an "act of aggression."
Iranian officials confirmed the ship had been traveling from China when it was intercepted — a detail that adds political weight to Beijing's response.
Iran also confirmed it was closing the Strait of Hormuz once again to most shipping traffic, blaming Washington for what it described as repeated breaches of the ceasefire agreement. Parliamentary Speaker Mohammad Bagher Ghalibaf stated plainly: "It is impossible for others to pass through the Strait of Hormuz while we cannot."
Beijing Expresses "Concern" — But Stops Short of Open Confrontation
China's Foreign Ministry spokesperson Guo Jiakun addressed the incident on Monday during a regular press briefing in Beijing, describing the American action as a "forced interception" and calling the situation in the Strait "sensitive and complicated."
Guo urged all relevant parties to avoid further escalation and to create conditions for normal transit through the strait to resume. He also called on the parties involved to "continue to maintain the momentum of the ceasefire and negotiations," and expressed hope that the existing window for diplomacy could lead to a faster end to the conflict.
Beijing's measured language reflects its difficult position. China imports roughly half of its crude oil from the Persian Gulf, including a significant share from Iran through third-country transshipments. The Strait of Hormuz is not just a geopolitical flashpoint for China — it is an economic lifeline.
The Bigger Picture: A Fragile Ceasefire Under Strain
The naval confrontation comes at a particularly delicate moment. President Trump announced on Sunday that U.S. negotiators — including Vice President JD Vance, special envoy Steve Witkoff, and Jared Kushner — would travel to Islamabad, Pakistan, for a new round of peace talks with Iran.
But those talks are now in doubt. Iran's Foreign Ministry spokesperson signaled that the government has no plans to participate in a new round of negotiations following the ship seizure.
Oil prices reacted sharply, with Brent crude climbing roughly 7% to around $96 per barrel on Sunday. With no tankers passing through the Strait and an uncertain diplomatic outlook, energy markets remain volatile.
Trump, for his part, took a hardline stance. He accused Iran of firing on ships in the strait — including vessels from France and the United Kingdom — calling it a "total violation" of the ceasefire. He warned that if Iran does not agree to a deal, the U.S. would strike Iranian power plants and bridges.
China's Strategic Dilemma
Beijing finds itself in an increasingly uncomfortable position. China has long backed the regime in Tehran and is the largest buyer of Iranian crude oil. At the same time, Trump has signaled that countries supplying Iran with weapons risk facing new tariffs of up to 50 percent — a direct warning aimed at Beijing. China denied it was planning to supply Iran with shoulder-fired air defense systems.
China's stated top priority has been to prevent the resumption of open warfare and to maintain what Beijing calls the "hard-won momentum of the ceasefire." Whether that goal is still achievable — with a seized ship, a blocked strait, and stalled talks — remains deeply uncertain.
What Comes Next
The coming days will be critical. If U.S. and Iranian negotiators do sit down in Islamabad, they face steep hurdles: Iran's refusal to abandon its nuclear program, the ongoing blockade, and now the seizure of a cargo vessel that Tehran is calling an act of war.
China's role in any diplomatic solution should not be underestimated. Beijing reportedly helped push Iran toward the initial ceasefire negotiations. Whether it can do so again — and whether Washington will give it the space to try — may determine how this high-stakes standoff unfolds.
