U.S. says Iran rejected uranium supply proposal as peace talks remain stalled

The United States offered to supply Iran with uranium for a civilian nuclear program under an arrangement intended to prevent Tehran from producing enriched uranium domestically, U.S. Ambassador to the United Nations Mike Waltz said Sunday. According to Waltz, Iran rejected the proposal.

Waltz said Washington remained open to an Iranian civilian nuclear program if Tehran complied with international law, inspection requirements and the Nuclear Non-Proliferation Treaty. He compared the proposed arrangement to the United Arab Emirates’ nuclear agreement with the U.S., under which the UAE does not enrich uranium or reprocess spent fuel domestically.

The envoy said possible measures also included Iran surrendering its stock of highly enriched uranium and accepting safeguards preventing it from rebuilding that capacity. Iran maintains that its nuclear activities are peaceful and intended for electricity generation, medicine and research.

Separately, Waltz said the Trump administration rejected Iran’s latest proposal to end the war because Tehran sought extensive sanctions relief before further negotiations. President Donald Trump said he expected additional talks in the coming week but did not accept Iran’s current terms.

Iranian Foreign Minister Abbas Araghchi said diplomacy remained possible and linked reopening the Strait of Hormuz to Iran’s conditions being met, while also saying the country was prepared for renewed fighting. Iranian President Masoud Pezeshkian said Tehran was ready to discuss its nuclear program and other issues but would not accept coercion.
