Nuclear inspections, frozen assets, Strait of Hormuz: Key fault lines in US-Iran talks
While both sides described the talks as constructive, significant differences remain on several key issues
The first round of high-level negotiations between the United States and Iran, held in Switzerland and described by US Vice President J.D. Vance as constructive, concluded with significant disagreements on key issues. While Vance stated Iran would allow strengthened nuclear inspections and linked the release of frozen assets to future commitments, Iran insisted its International Atomic Energy Agency engagement would remain within existing safeguards and domestic laws, with its Foreign Ministry claiming some sanctions relief and asset releases had already occurred. Further divergence emerged over the Strait of Hormuz, with the US advocating for its unrestricted international shipping while Iran's Parliament Speaker declared it would be managed under its own framework, distinct from pre-war arrangements, and reiterated Iran's ongoing distrust of the United States.

Even as the first round of high-level negotiations between the United States and Iran concluded on Sunday, with both sides describing the talks as constructive, significant differences remain on several key issues.
On Monday, US Vice President J.D. Vance, who led the American delegation during talks held in Switzerland, said Iran would allow nuclear inspectors to return to the country following what he described as a "very, very good" first day of negotiations.
Speaking to reporters at the Burgenstock resort, Vance said the inspection mechanisms would be strengthened to ensure that Tehran is unable to develop nuclear weapons.
However, Iran pushed back and insisted that its engagement with the International Atomic Energy Agency (IAEA) would continue strictly within the framework of existing safeguards obligations and domestic laws.
"Iran's interactions with the Agency, in accordance with Iran's obligations under the Safeguards Agreements, will continue according to existing procedures and comply with the laws enacted by the Islamic Consultative Assembly and the decisions of the Supreme National Security Council (SNSC)," Iranian Foreign Ministry spokesperson Esmaeil Baqaei told state-run news agency IRNA.
Differences have also surfaced over the issue of frozen Iranian assets. While Vance said any release of frozen funds would depend on Tehran's future commitments and verification measures, Iranian officials maintained that Washington had already agreed to ease restrictions and release some sanctioned assets.
“Fundamentally, that money is not going to be unfrozen unless we continue to see progress, and that will obviously be a big part of the negotiation in the days to come,” Vance said after returning to the United States from Switzerland.
Iranian Foreign Minister Seyed Abbas Araghchi, however, presented a markedly different account of the talks, suggesting that some sanctions relief measures had already taken effect.
“Oil and petrochemical exports have been waived, the blockade has been lifted, some frozen assets have been released, and a major reconstruction and development plan has been launched for Iran,” Araghchi said.
Another major point of divergence concerns the Strait of Hormuz. While Washington has maintained that the strategic waterway should remain fully open to international shipping, Tehran has indicated that the strait will not return to its pre-war operational arrangements.
Iranian Parliament Speaker Mohammad Bagher Ghalibaf said Tehran would manage the vital shipping route under its own framework while continuing to adhere to international regulations.
“Everyone should know that the administration of the Strait of Hormuz will never go back to the way it was before the war,” he said.
Ghalibaf also linked the ongoing negotiations to broader regional conflicts, including developments in Lebanon, and reiterated Iran's longstanding distrust of the United States. “We have never trusted the Americans; we don't trust them now, and it is only reasonable to remain distrustful in the future".
