US‑Iran talks deadlock over uranium

Abbas Araghchi said on May 15 that Iran and the United States had reached a deadlock over Tehran’s enriched uranium, turning a technical issue back into the central obstacle in any new nuclear understanding. The Iranian foreign minister told reporters in New Delhi that the question of Iran’s “enriched material” was so difficult that both sides had effectively deferred it to a later stage. A live YouTube broadcast posted on May 16 amplified that remark and framed enrichment, verification and inspection access as the main sticking points. The available reporting does not identify a fresh mediator or a new formal negotiating timetable. ### What exactly did Araghchi say is stuck? Abbas Araghchi told reporters on May 15 that the dispute centers on Iran’s enriched uranium stockpile, not a broad breakdown in all contacts. He said the issue had become “very complicated” and was close to deadlock, according to multiple reports of his remarks in New Delhi during BRICS-related meetings. Iranian and regional outlets said both sides had agreed to postpone that question to later phases of talks. (en.apa.az) New Delhi was the setting for those comments, and Araghchi also said Tehran doubted Washington’s seriousness about negotiations. That matters because his public formulation suggests the channel has not necessarily closed, but that the hardest file — what happens to existing enriched uranium — remains unresolved. That last point is an inference from his remarks and the way the issue was separated from other discussion tracks. (en.apa.az) ### Why is the stockpile the hardest part? The International Atomic Energy Agency said Iran had accumulated 440.9 kilograms of uranium enriched up to 60% U-235 by the time of the military attacks in mid-June 2025. That is the most concrete public number attached to the current dispute, because any deal would have to determine whether that material stays in Iran, is diluted, is shipped out, or is placed under some other monitored arrangement. (aljazeera.com) Rafael Grossi, the IAEA director general, said on June 22, 2025 that inspectors needed to “account for the stockpiles of uranium, including, most importantly, the 400kg enriched to 60%.” Grossi’s formulation tied the political dispute directly to a safeguards problem: before any arrangement can be judged, inspectors need to establish what material exists and where it is. (iaea.org) ### Where do inspections and verification enter the dispute? The IAEA said after the June 2025 attacks that it stopped verification activities in Iran and withdrew inspectors for safety reasons by the end of that month. In later reporting, the agency said it had lost continuity of knowledge about Iran’s inventories of low enriched and high enriched uranium, language that goes to the core of any future verification regime. (iaea.org) Iran’s cooperation also narrowed after July 2, 2025, when the IAEA said Tehran enacted a law suspending cooperation with the agency. The agency reported that since June 13, 2025 it had not had access to safeguarded nuclear facilities in Iran other than the Bushehr Nuclear Power Plant. That means inspection access is not a side issue; it is part of the same practical problem as the stockpile itself. (iaea.org) ### Is there any sign of a formula for the uranium? Araghchi said on May 15 that transferring Iran’s enriched uranium was not under discussion “for the time being,” according to Iranian state-linked reporting. He also said he had spoken with Russian officials about Moscow’s offer to store Iranian enriched uranium and that Tehran could examine that proposal later if talks reached that stage. (iaea.org) Russia appears in the background as a possible technical custodian, but the current reporting does not show a new agreed mechanism among Washington, Tehran and Moscow. The YouTube clip cited by the user also did not identify a mediator or a date for the next negotiating round. ### What can be said now, and what remains unverified? (presstv.ir) The verified core is narrow. Abbas Araghchi publicly said the enriched uranium issue is in deadlock. The IAEA has publicly documented both the size of Iran’s 60% stockpile before the 2025 attacks and the subsequent loss of inspection continuity. Grossi has publicly said inspectors must return and account for the material. (youtube.com) The unverified part is the diplomatic architecture around any restart. Available sources reviewed here do not establish a new mediator, a scheduled negotiating session, or a U.S. public readout matching Araghchi’s latest description. The next concrete development will be any announced U.S.-Iran contact or any IAEA statement that inspectors have regained access to Iranian nuclear sites. (en.apa.az) (youtube.com)
