Following the fifth round of Oman-mediated talks between Tehran and Washington, which concluded in Rome on May 23, speculation is mounting over a bold new proposal reportedly floated by Iran: a regional nuclear enrichment consortium involving several Middle Eastern countries. The plan, aimed at overseeing Iran’s uranium enrichment program, could offer a face-saving path forward in long-stalled US-Iran nuclear negotiations.

Omani mediators noted "some but not conclusive progress" in the latest round, and Iranian Foreign Minister Abbas Araqchi called the discussions one of the "most professional rounds" to date, though he acknowledged the talks remain complex and unresolved. The two sides remain deeply at odds over the central issue of uranium enrichment — a rift that continues to block progress despite the highest-level contacts since the US withdrew from the 2015 Joint Comprehensive Plan of Action (JCPOA). The proposed consortium, if seriously pursued, is likely to resurface at future talks.

Last week, US negotiator and Middle East envoy Steve Witkoff underscored Washington’s red line, stating that it would not accept “even one percent of an enrichment capability.” Iranian Foreign Minister Abbas Araghchi shot back, affirming Tehran’s stance that it would continue enrichment “with or without a deal.”

From Iran’s perspective, uranium enrichment is “non-negotiable.” Talks, by all accounts, are careening toward a dead end.
