The United States and Iran agreed to move forward with nuclear talks following direct and indirect discussions in Muscat on May 11, sources close to negotiations said, citing a senior US administration official.

White House envoy Steve Witkoff held talks with Iranian officials during the fourth round of negotiations in Oman's capital. The meeting, which lasted more than three hours, included both direct and indirect discussions with Iranian Foreign Minister Abbas Araghchi, according to a source with knowledge of the proceedings.

"Agreement was reached to move forward with the talks to continue working through technical elements. We are encouraged by today's outcome and look forward to our next meeting, which will happen in the near future," the US official said.

Iran's Foreign Ministry spokesman Esmaeil Baqaei characterised the discussions as "difficult but useful talks to better understand each other's positions and to find reasonable and realistic ways to address the differences."

The next round of negotiations will be coordinated and announced by Oman, Baqaei confirmed on social media.

The Muscat meeting followed Araghchi's statement on May 10 that a fresh nuclear agreement with the United States is "entirely within reach" provided Washington limits its objectives to preventing the development of nuclear weapons, according to Dolat.ir.

"If the purpose of the talks is to guarantee that Iran will never build nuclear weapons, that has already been achieved," Araghchi told the fourth Iranian–Arab Dialogue Forum in Doha. "But if the aim is to strip Iran of its lawful nuclear rights and to impose other unreasonable conditions, the Islamic Republic will not compromise on the legitimate demands of the proud Iranian nation."

The Iranian foreign minister confirmed that indirect negotiations with the United States were due to resume on May 11 and noted that parallel discussions are underway with the European Union, China and Russia.

Araghchi emphasised that nuclear weapons are forbidden under the Islamic principles of the Republic while insisting on Iran's non-negotiable right to enrich uranium within international legal frameworks. "Western states and all who claim to oppose nuclear weapons must abandon their double standards," he added.

The talks mark the fourth round of US-Iran negotiations, with Oman continuing its role as mediator between the two nations. The Gulf state has frequently served as a diplomatic channel between Washington and Tehran.

Araghchi's diplomatic tour included a meeting with his Saudi counterpart Prince Faisal bin Farhan in Jeddah on May 10, where he briefed the Saudi foreign minister on the latest developments related to indirect talks between Iran and the United States.

The high-level meeting follows the gradual restoration of diplomatic relations between Tehran and Riyadh after years of tensions, with the two regional powers re-establishing formal ties last year following mediation efforts by China.

During the Jeddah meeting, Araghchi stressed "the necessity for the Islamic world to address threats and challenges, especially regarding occupied Palestine, stopping the genocide, and preventing the colonial conspiracy to erase Palestine."

Iran is committed to improving relations with its neighbours through dialogue grounded in respect and trust, Araghchi emphasised in Doha. "We have learned that our common interests outweigh our disagreements."
