US and diplomatic sources have said that Russia may assume a pivotal role in a potential nuclear agreement with Iran.
Under one proposal, Moscow would serve both as the custodian of Iran’s highly enriched uranium stockpile and as an independent guarantor in the event of violations, Caliber.Az reports per foreign media.
The renewed negotiations follow US President Donald Trump’s withdrawal from the 2015 Joint Comprehensive Plan of Action (JCPOA) during his first term. Trump has since threatened military action unless a new deal is struck soon to prevent Iran from acquiring a nuclear weapon.
Four hours of indirect talks, mediated by Oman in Rome, yielded "significant progress," US officials said. Further technical negotiations are planned for Geneva this week, with a senior-level diplomatic meeting expected in Oman next weekend. Steve Witkoff, Trump’s special envoy who led the US delegation in Rome, is pushing for an agreement within 60 days.
However, Iran’s Foreign Minister Abbas Araghchi has expressed skepticism, citing “distrust” and complex technical hurdles. A major sticking point remains the future of Iran’s uranium stockpile. While Tehran prefers to retain the material within its borders, the US favors either its destruction or transfer to a third country — likely Russia. Witkoff, who previously caused confusion by appearing to support dismantling Iran’s entire nuclear program, reportedly clarified in Rome that such statements were “political messaging.”
Mohamed Amersi of the Wilson Center explained: “From the Iranian perspective there had been some conflicting messages… If he had not got that assurance it’s likely the whole negotiation would have been wrapped up, and ended immediately.”
A proposed enforcement mechanism could allow Russia to return the uranium to Iran if the US breaches terms — a move that may exclude European guarantors and reduce the UN’s involvement. Talks gained momentum after Saudi Arabia’s defense minister visited Tehran, signaling regional backing for diplomacy over confrontation.
Oman’s foreign ministry reaffirmed the goal of a “fair, sustainable and binding agreement” ensuring Iran remains free of nuclear weapons while preserving peaceful nuclear development.
