ERBIL, Kurdistan Region of Iraq – Iranian Foreign Minister Abbas Araghchi on Sunday said that his ministry was reviewing proposals for a prospective nuclear deal with the United States issued by Oman.

Speaking at an event commemorating the African Union’s foundation in Tehran, the Iranian top diplomat told reporters that the proposals in question were put forward by his Omani counterpart, Badr bin Hamad Al Busaidi, during the fifth round of US-Iran nuclear talks in Rome on Friday.

Oman has served as a mediator in the tentative negotiations between Washington and Tehran, hosting talks in its capital of Muscat and offering its diplomatic facilities in Italy as a venue for other bouts of negotiations.

Iran and the US began indirect negotiations in April relating to the former’s burgeoning nuclear program, with Washington fearing that Tehran will pursue nuclear weapons proliferation and seeking to quash the prospect with a deal. Iran, on the other hand, insists that its enrichment program is purely for peaceful purposes.

The Omani proposals seek to iron out recurrent issues that have hindered progress in the talks, chief among them Iran’s commitment to continue enrichment, ostensibly for civilian purposes, with or without an agreement.

US Special Envoy to the Middle East and chief negotiator Steve Witkoff has insisted that “an enrichment program can never exist in the state of Iran ever again. That’s our red line. No enrichment. That means dismantlement.”

“The US made its red line public in the media,” Araghchi said following the remarks. “Immediately after the Witkoff talks, we made our issue public and announced that Iran's enrichment would continue.”

Spokesperson of the Iranian foreign ministry Esmail Baghaei on Monday denied claims suggesting that Iran had backed down from this policy, saying, "This information is a figment of the imagination and totally false.”

During his first term in 2018, US President Donald Trump walked away from a landmark nuclear deal with Iran, which was introduced three years earlier in 2015 by his predecessor Barack Obama. Known as the Joint Comprehensive Plan of Action (JCPOA), the deal provided sanctions relief to Iran in exchange for the placement of curbs on Iran’s nuclear program.

According to the International Atomic Energy Agency (IAEA), Iran currently holds over 8,000 kilograms of enriched uranium, of which 274.8 kilograms is at 60 percent purity—far surpassing the JCPOA's limits. Araghchi has echoed the report’s findings, saying that Iran’s “nuclear program has advanced compared to the pre-JCPOA period.”
