WASHINGTON

Talks between the US and Iran "made progress," but additional details need to be addressed, a US official said Tuesday.

"Progress was made, but there are still a lot of details to discuss. The Iranians said they would come back in the next two weeks with detailed proposals to address some of the open gaps in our positions," said the official.

Iranian Foreign Minister Abbas Araghchi said earlier Tuesday that “more serious discussions” were held during the latest round of indirect nuclear negotiations, describing the atmosphere as “more constructive.”

Speaking to reporters after the conclusion of the second round of talks in Geneva, Araghchi said the parties reached a general agreement on a set of “guiding principles” to serve as a basis for beginning work on the text of a potential agreement.

“It was decided that both sides will work on the drafts of a potential agreement, and after exchanging the texts,” he said. “The timing of the next round of talks will be determined.”

Iran’s top diplomat added that a clear path lies ahead for nuclear negotiations with the American side, which is “assessed positively” from Iran’s perspective.

He cautioned, however, that progress does not mean a quick agreement has been reached, but the negotiation process has started, and “good progress” has been made.

“Both sides,” he stressed, “have positions that will take some time to bring closer together.”

Araghchi said no specific date has been set for the next round, noting that it is not yet possible to speak of a roadmap.

Omani Foreign Minister Badr Albusaidi, for his part, said Tuesday’s talks concluded with “good progress towards identifying common goals and relevant technical issues.”

Writing on US social media company X, Albusaidi described the talks as “constructive,” noting that the parties “made serious efforts” to define guiding principles for a final deal.

He expressed appreciation for the contribution of the UN nuclear agency chief Rafael Grossi, while stressing that further work remains ahead of the next meeting.

Iranian state media reported that Tuesday’s talks focused primarily on the technical aspects of the nuclear negotiations.

According to reports, the two sides exchanged notes on technical issues, with the participation of experts in nuclear, legal and economic matters.
