The fragile deal between the United States and Iran has taken another tentative step forward, with the head of the International Atomic Energy Agency (IAEA) confirming that inspectors will indeed visit sites in Iran as part of the preliminary agreement. Rafael Grossi, Director General of the IAEA, made his remarks while on a visit to Japan, where he stated that the agency would be "working on the modalities" – dates, procedures, and places – for the inspections.
Mr Grossi's confirmation comes amidst a backdrop of conflicting statements from Washington and Tehran regarding the scope and timing of IAEA access. Iran's Deputy Foreign Minister, Kazem Gharibabadi, has been keen to stress that any inspection of damaged nuclear facilities or nuclear material would only be considered within the framework of a final deal with the US, once practical steps have been taken to lift all sanctions.
The IAEA chief's comments are significant because they highlight the delicate nature of the ongoing negotiations. Mr Grossi has consistently sought to maintain a neutral stance in these talks, while also stressing the importance of the IAEA's role in ensuring that Iran's nuclear activities are subject to international supervision. As such, his confirmation is likely to be welcomed by British diplomats, who have been closely following developments in this complex web of negotiations.
The preliminary US-Iran agreement has several key implications for the UK and its allies. The deal includes provisions for unimpeded shipping through the Strait of Hormuz, which could help to reduce tensions with Iran and alleviate concerns about global energy security. The price of Brent crude oil has already begun to reflect this development, falling below $75 (£57) for the first time since the US-Israeli conflict with Iran began.
US Secretary of State Marco Rubio's recent diplomatic tour of Gulf nations is also part of a broader effort to solidify a more comprehensive agreement. In Kuwait City, Mr Rubio reiterated the US commitment to not undermine the security of its regional allies, stating that negotiators are likely to meet again in Switzerland before the end of the month.
The dispute over IAEA access has been a central point of contention throughout these negotiations. Earlier statements from US Vice-President JD Vance suggested Iran had agreed to invite IAEA inspectors back into their country, only for an Iranian foreign ministry spokesman to deny "detailed discussions" and plans for access to facilities bombed during the recent conflict. Mr Grossi acknowledged this "war of words" but emphasised that a signed memorandum of understanding between both presidents explicitly mandates IAEA supervision of nuclear activities.
