CHINA PERSPECTIVE

Beijing reads the Strait of Hormuz crisis as an early indicator of fragility in the June 17 US-Iran memorandum of understanding, while weighing its direct exposure as the world's largest crude oil importer. Any sustained interruption of flows through this strategic chokepoint carries immediate consequences for Chinese energy security.

Iran's announcement of strait closure, issued Saturday by the Khatam al-Anbiya central military command, invokes two grievances: Washington's "contract violation" and the "continuous, relentless Israeli strikes in violation of the ceasefire in southern Lebanon." On the ground, competing claims shape the narrative. US Central Command asserts that 55 merchant vessels transited the strait Saturday, delivering approximately 17 million barrels to global markets, according to the South China Morning Post. Vice President Vance, appearing on Fox News, denied any effective closure: "We see no evidence that the Iranians are actually closing the Strait of Hormuz. It will take time to clear the mines."

Diplomacy has not halted despite rising tensions. US and Iranian negotiators converged Sunday on a Swiss resort, accompanied by Pakistan and Qatar in their roles as mediators. Pakistani Prime Minister Shehbaz Sharif and military chief Asim Munir joined the delegations. Iran dispatched a high-ranking team including Parliament Speaker Mohammad Bagher Ghalibaf, Foreign Minister Abbas Araghchi, and central bank governor Abdolnaser Hemmati. Vance expressed hope for "a few days of discussions" to "make progress on the nuclear question and ceasefire in Lebanon."

The June 17 memorandum, signed by Trump and Iranian President Masoud Pezeshkian, establishes a 60-day window to finalize a peace accord. Yet Saturday's renewed fighting between Israel and Hezbollah—each side accusing the other of ceasefire breach—nearly derailed talks already postponed Friday following deadly Israeli strikes in Lebanon. The fragility is evident: the strait has become Tehran's leverage point against any Israeli escalation that Washington cannot contain.

In practical terms, Indian supertankers including the Desh Vibhor, Desh Vaibhav, and Sanmar Herald reappeared in the Gulf of Oman after reporting their transit attempts late Friday, according to maritime tracking data from the SCMP. Their reemergence suggests traffic continues despite extreme tension, complicating any narrative of a hermetically sealed strait.
