Using Reuters, Omani statements, IAEA statements, PBS’s timeline compilation, the UK Parliament briefing, and public statements by Iranian officials,
What Iran had actually signaled willingness to do (April–May 2025)
CONFIRMED
Iranian officials publicly indicated willingness to:
- Continue negotiations through multiple rounds.
- Accept some form of nuclear restrictions.
- Accept IAEA verification and monitoring as part of a deal.
- Provide assurances that Iran would not acquire nuclear weapons.
- Discuss limits on enrichment levels and stockpiles in exchange for sanctions relief.
For example, the fourth round in Muscat ended with both sides agreeing to continue talks despite major disagreements. Reuters reported that negotiations continued while Iran maintained that some domestic enrichment was a red line.
IAEA Director General Rafael Grossi publicly described the negotiations as being at a “crucial stage” and discussed Iran potentially returning to broader monitoring arrangements.
ATTRIBUTED (reported by Iranian and international media, not jointly signed)
Several reported Iranian proposals circulated during the negotiations.
These included:
Proposal A: Return to low-level enrichment
Iran reportedly proposed:
- reducing enrichment toward 3.67%,
- restoring broader IAEA inspections,
- implementing the Additional Protocol,
- transferring or otherwise resolving highly enriched uranium stockpiles,
in exchange for sanctions relief, oil export permissions, and access to frozen assets.
Proposal B: Phased sanctions-for-nuclear-limits formula
Reportedly:
Phase 1
- lower enrichment,
- access to frozen assets,
- oil export waivers.
Phase 2
- restore stronger inspections,
- halt higher-level enrichment.
Phase 3
- broader sanctions removal and resolution of enriched uranium stockpiles.
However, these proposals were never publicly announced by Oman as accepted by both sides and were never confirmed in a signed document during April–May 2025.
CONTRADICTED / UNRESOLVED
The central dispute remained uranium enrichment.
Iran’s position (CONFIRMED)
Iran repeatedly stated:
domestic uranium enrichment is non-negotiable.
Reuters reported Iranian officials maintaining enrichment as a red line throughout the talks.
U.S. position (CONFIRMED)
Reuters reported U.S. officials increasingly insisting that:
Iran must stop enrichment or drastically curtail it.
Secretary of State Marco Rubio and Special Envoy Steve Witkoff publicly articulated positions that conflicted with Iran’s insistence on retaining domestic enrichment.
What Oman publicly said after five rounds
Oman never announced:
- an agreed enrichment level,
- an agreed sanctions package,
- an agreed stockpile disposition plan,
- an agreed final framework.
After the fifth round, Oman said the parties had made:
“some but not conclusive progress.”
No final agreement was announced.
Bottom line
CONFIRMED
By the end of the five rounds (April–May 2025), Iran had signaled willingness to discuss:
- nuclear limits,
- IAEA monitoring,
- verification measures,
- restrictions on enrichment levels,
- restrictions on stockpiles,
provided sanctions relief was included.
ATTRIBUTED
Iran reportedly offered:
- enrichment near JCPOA levels,
- Additional Protocol inspections,
- resolution of highly enriched uranium stockpiles,
- phased implementation tied to sanctions relief.
CONTRADICTED
No evidence from Reuters, Oman, or official statements shows that Iran agreed to:
- eliminate all domestic enrichment,
- dismantle its nuclear program,
- surrender enrichment rights permanently.
That issue remained unresolved when negotiations were interrupted in June 2025.
