IAEA Chief Insists Iran Nuclear Inspections 'Going to Happen' Despite Tehran's Denials

    VIENNA/TOKYO – The head of the International Atomic Energy Agency (IAEA) has firmly declared that inspections of Iranian nuclear sites will proceed under a recent U.S.-Iran interim agreement, pushing back against categorical denials from Tehran . The conflicting statements have cast a shadow over the fragile ceasefire and highlighted the significant challenges remaining in implementing the diplomatic breakthrough.

    Speaking to reporters on Wednesday during a visit to Japan, IAEA Director General Rafael Grossi stated that the memorandum of understanding signed by U.S. President Donald Trump and Iranian President Masoud Pezeshkian "explicitly" provides for agency oversight of nuclear material and facilities . "Obviously, to do that, we will have to inspect. Whether this happens the day after tomorrow or in one week or in 10 days, it's important, but not essential. This is going to happen," Grossi said . He dismissed contradictory political statements as secondary to the signed accord .

    A Dispute Over Terms and Access

    The dispute began on June 22 when U.S. Vice President JD Vance, following negotiations in Switzerland, announced that Iran had agreed to invite IAEA inspectors back to the country, calling it a "major milestone" and the "first step in permanently denuclearizing Iran" . President Trump subsequently confirmed the agreement on social media, stating Iran had "fully and completely agreed" to the highest level of long-term nuclear inspections and that the U.S. would keep the Strait of Hormuz open and end its naval blockade .

    However, these assertions were swiftly and publicly rejected by Iran. Foreign Ministry spokesman Esmaeil Baghaei told reporters in Tehran that there is no plan for IAEA inspectors to visit Iranian nuclear facilities damaged during the conflict with the U.S. and Israel last year . He argued that no international mechanism exists for inspecting such damaged sites and that Iran will only continue its existing routine procedures under the Nuclear Non-Proliferation Treaty (NPT) . Semi-official Iranian media, citing a source, described Vance's claims as "false," asserting that no such discussions took place in Switzerland .

    The Core of the Disagreement

    This contradiction centers on the status of Iran's uranium enrichment facilities. Since the 12-day war in 2025, Tehran has blocked IAEA inspectors from these sites, where Western experts believe a stockpile of highly enriched uranium sufficient for up to ten nuclear warheads may be stored . While the IAEA has maintained access to other facilities, such as the Bushehr nuclear power plant, the lack of access to enrichment sites has prevented the agency from verifying the status of Iran's nuclear material and centrifuge operations .

    The interim agreement, signed last week, mandates that Iran reduce the enrichment level of its uranium stockpile. Grossi emphasized that the agency’s supervision is a key component of this commitment . The U.S. Treasury has issued a temporary 60-day license authorizing the sale of Iranian oil as part of the peace framework, and the parties have established four working groups to address sanctions, nuclear issues, reconstruction, and implementation .

    Despite Grossi's firm stance, uncertainty remains. Iranian officials have reiterated that no agreement has been reached on IAEA inspections, with Deputy Foreign Minister Kazem Gharibabadi stating that Iran has "no plans to grant access to the targeted facilities" . The U.S. and Iran have until mid-August to negotiate a more comprehensive final agreement.
