The two sides plan to resume negotiations soon after consultations in their countries' capitals, with technical-level discussions scheduled to take place next week in Vienna, Omani Foreign Minister Sayyid Badr Albusaidi said in a post on X after the day's meetings in Switzerland.

Badr Albusaidi will hold talks with U.S. Vice President JD Vance and other U.S. officials in Washington on Friday, MS NOW reported late on Thursday. Neither the White House nor Oman's embassy in Washington immediately responded to requests for comment.

Any substantial move toward an elusive agreement between longtime foes Washington and Tehran could reduce the imminent prospects for U.S President Donald Trump to carry out a threatened attack on Iran that many fear could escalate into a wider war.

But Tuesday's indirect talks wrapped up without a deal, still leaving the region on edge.

The Omani minister's upbeat assessment followed indirect talks between Iranian Foreign Minister Abbas Araqchi and U.S. envoys Steve Witkoff and Jared Kushner in Geneva, with one session in the morning and the second in the afternoon.


"We have finished the day after significant progress in the negotiation between the United States and Iran," Badr Albusaidi said.

But with many analysts seeing the latest diplomacy as the last chance before Trump could decide to go to war, Badr Albusaidi provided no details and stopped short of saying the two sides had overcome their biggest stumbling blocks to a deal.

Describing the talks as some of the most serious that Iran has had with the U.S., Araqchi told Iranian state television: "We reached agreement on some issues, and there are differences regarding some other issues."

“It was decided that the next round of negotiations will take place soon, in less than a week," he said. The Iranians, he added, had clearly expressed their demand for lifting of U.S. sanctions, which Washington has long insisted will only come after deep concessions from Tehran.
