Iran’s Supreme National Security Council Secretary and advisor to Iran's Supreme Leader Ayatollah Ali Khamenei, Ali Larijani, will travel to Muscat, Oman, on Tuesday, leading a delegation, state-run Tasnim News Agency reported on Monday.

During the visit, Larijani will meet with senior Omani officials to discuss “the latest regional and international developments and bilateral cooperation at various levels,” the report said.

This comes after last Friday, when US special envoy Steve Witkoff, Jared Kushner, and US Central Command Commander Adm. Brad Cooper met with Araghchi and other Iranian senior officials in Oman.

The first meeting was described as a “good meeting,” focusing mainly on how the negotiations would be conducted rather than on the core issues themselves, the sources said. The Americans expect the Iranians to come to the next meeting prepared to offer concessions on the nuclear issue and other matters, they added.

The Trump administration has told Iran that it expects the Iranian delegation, led by Foreign Minister Abbas Araghchi, to arrive at their next meeting “with meaningful substance,” two people familiar with the matter told The Jerusalem Post on Sunday.

Araghchi: Complete halt to uranium enrichment unacceptable to Iran

On Sunday, Araghchi said a complete halt to uranium enrichment was absolutely unacceptable to Iran.

“The discussions should focus on scenarios in which uranium enrichment continues, alongside assurances that the enrichment is solely for peaceful purposes,” he said.
