US and Iranian representatives converged on Doha on Tuesday for what Washington billed as a new round of talks to shore up a fragile ceasefire, but the effort got off to a shaky start as Iran insisted it would hold 'no negotiations at any level' with the United States, leaving Qatari mediators to bridge the two sides.

President Trump said Iran had 'requested a meeting' in the Qatari capital, and US Middle East envoy Steve Witkoff and the president's son-in-law and adviser Jared Kushner traveled to Doha. But Qatar's Foreign Ministry spokesman, Majed Al Ansari, said the American officials would meet Qatari mediators rather than Iranian counterparts, and that no high-level US-Iran meeting was planned for the day.

Iran sent its own technical delegation to Doha but went out of its way to deny any link to the American visit. Foreign Ministry spokesman Esmaeil Baghaei said, 'We will not have any negotiation meetings at any level with the American side in the coming days,' and that the Iranian team's trip 'has nothing to do' with the US officials' presence. Senior negotiator Kazem Gharibabadi said reports of confirmed technical talks were inaccurate.

Iranian officials said their delegation's focus was narrow: the release of some $6 billion in Iranian assets frozen in Qatar under the framework reached earlier in the month, rather than the broader political and security questions Washington wants to address. The dueling characterizations underscored how far apart the two governments remain even on whether they are talking.

The central dispute concerns the Strait of Hormuz. Article 5 of the memorandum of understanding signed on June 17 calls for safe passage of commercial vessels through the waterway at no charge for 60 days, but the two sides read it differently. Iran, through adviser Ali Akbar Velayati, has pressed its demand to collect transit fees and asserts a regulatory role over shipping, while the United States and Gulf Arab governments reject any charges and insist on unhindered transit. Iran has also objected to US-designated shipping routes near Oman as a violation of the deal.

The talks follow a dangerous weekend in which the ceasefire nearly unraveled. Iran's Revolutionary Guard claimed drone and missile attacks on Bahrain and Kuwait, which it said were retaliation for US strikes, prompting Trump to accuse Tehran of violating the truce. By Monday, both sides had signaled they would 'stand down for now,' and markets steadied, with oil holding below $70 a barrel.

France and Oman, meanwhile, have agreed to work with international partners on demining the strait, an effort Iran has called 'sensitive and complex.' With direct dialogue stalled, the immediate path forward runs through Doha's mediators, and the durability of the ceasefire may hinge on whether they can translate parallel, deniable visits into a workable understanding over the world's most important oil chokepoint.
