Iran and the U.S. have begun their fourth round of indirect negotiations in Muscat, Oman, focusing on nuclear issues and potential sanctions relief. The discussions, led by Iranian Foreign Minister Abbas Araqchi and U.S. Special Envoy Steven Witkoff, are facilitated by Oman’s Foreign Minister Badr bin Hamad Al Busaidi. Araqchi reaffirmed Iran’s non-negotiable stance on uranium enrichment, which he described as a vital national achievement. He expressed optimism for productive talks, emphasizing the importance of dialogue at the negotiation table. This round follows previous discussions that began on April 12, marking significant engagement since the U.S. exited the 2018 agreement.
