Washington and Tehran are at odds not only over their assessments but also over the interpretation of recent understandings. While U.S. officials, including Vice President JD Vance, publicly state that Iran has agreed to readmit International Atomic Energy Agency (IAEA) inspectors, the Iranian side categorically denies these claims, casting serious doubt on the reality of the reached agreements.
On June 22, during a press conference in Switzerland, Vice President JD Vance announced that the Iranian delegation had agreed to re-invite IAEA inspectors to its nuclear facilities and that experts could arrive in the country as early as this week. Washington viewed these remarks as a major diplomatic triumph. On his Truth Social platform, Trump emphasized that Iran had "fully and completely" consented to high-level inspections.
However, on June 23, Iranian Foreign Ministry spokesperson Esmail Baghaei issued a sharp denial of these assertions. He stated that Tehran and the IAEA have no current agreements to resume inspections, no meeting with IAEA Director General Rafael Grossi took place, and there are no plans to grant access to nuclear sites damaged during bombings. "The answer to both questions is no," the diplomat declared. Representatives from the Iranian news agency IRNA added that Iran did not discuss the nuclear issue during the talks at all and has not undertaken any new obligations toward the United States.
This discrepancy in positions highlights a more profound issue: the two sides are interpreting the memorandum of understanding signed on June 18 after 18 hours of negotiations at the Swiss resort of Bürgenstock differently. The Iranian delegation was comprised of Parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi, while the American side was represented by Vice President Vance, with assistance from IAEA Director General Rafael Grossi.
Under the terms of the memorandum, both parties pledged to enter a 60-day negotiation period to finalize an agreement on nuclear issues, including the fate of Iran’s enriched uranium stockpiles—estimated at approximately 440 kg of material enriched to 60 percent—and the comprehensive lifting of sanctions. Iran also committed to forgoing nuclear weapons development, while the U.S. agreed to lift its naval blockade and initiate talks on economic recovery.
The IAEA's role during this 60-day window was considered critical by both parties; however, while Washington envisions active monitoring and fresh inspections, Tehran maintains that access to damaged facilities depends on the outcome of negotiations and is not automatic. Consequently, conflicting signals from the two capitals are already undermining the fragile consensus and raising serious questions about the durability and viability of the agreement.
Whether diplomacy can bridge these fundamental gaps in interpretation remains the defining question for the weeks ahead. This conflict of statements demonstrates that even after intensive negotiations, the parties remain on opposite sides regarding key elements of nuclear verification, which significantly complicates the prospects for a final resolution.
