DUBAI – Iran and the United States are set to reconvene for a fourth round of nuclear negotiations this Sunday in Muscat, Oman, after a short postponement due to logistical reasons, Iranian Foreign Minister Abbas Araqchi confirmed Friday.
The talks come amid heightened tension, with U.S. President Donald Trump warning of military action if a new agreement to curb Iran’s nuclear program isn’t reached. Trump’s envoy, Steve Witkoff, is expected to attend the talks, according to sources.
Araqchi noted that the discussions are progressing but require more in-depth consultations as they advance into complex technical issues. “The negotiations are moving forward… and gradually entering into the details,” he said via Iranian state media.
This round was originally planned for May 3 in Rome but was delayed. Oman, acting as mediator, has now coordinated both sides for the rescheduled session.
The U.S. exited the original 2015 nuclear accord under Trump’s leadership, after which Iran expanded its nuclear activities. Western powers argue Iran’s enrichment program could lead to weapons development, while Tehran insists its goals are strictly civilian.
In a recent interview, Witkoff said the U.S. would accept Iran’s assurances that it does not seek nuclear weapons, but demanded dismantling of enrichment facilities and conversion to a strictly civil nuclear program.
Araqchi is also expected to visit Qatar and Saudi Arabia on Saturday to discuss the nuclear issue and address regional concerns.
