Iran and the United States ended the first day of high-level talks in Switzerland with cautious claims of progress, even as tensions over Lebanon, the Strait of Hormuz and President Donald Trump’s renewed threats continued to hang over the negotiations.
The talks, held at Bürgenstock near Lake Lucerne, were mediated by Qatar and Pakistan. A joint statement from the mediators said the two sides had agreed to a roadmap aimed at reaching a final deal within 60 days. Technical discussions between lower-level officials are expected to continue through the week.
Iranian Foreign Minister Abbas Araghchi said the first day produced “progress,” especially on efforts to end fighting in Lebanon. The Lebanon issue has become one of the biggest obstacles to the broader U.S.-Iran framework because Israeli strikes and Hezbollah activity threaten to unravel the ceasefire understandings.
According to the mediators’ statement, the U.S. and Iran agreed to create a communication line to reduce the risk of incidents in the Strait of Hormuz. They also agreed to establish a de-confliction mechanism with Lebanon’s government to help monitor the end of military operations there.
TRENDING TODAY
The talks followed a tense opening. Trump warned Iran that the United States could strike again if Tehran does not restrain its regional allies or if the Strait of Hormuz is closed. Iranian state media said the delegation paused participation after Trump’s comments, though U.S. officials later said negotiations were still continuing through mediators.
The Strait of Hormuz remains a central point of pressure. Iran has used threats over the waterway in response to continued fighting in Lebanon. The U.S. military has disputed claims that the strait was fully closed, but any disruption there could quickly affect global energy markets.
Sanctions relief is another major issue. Reports said the U.S. Treasury was preparing a 60-day waiver affecting Iranian oil and petrochemical sales. Iran also said access to some frozen assets held abroad was part of the understanding. It was not immediately clear whether the U.S. would place restrictions on how released funds could be used.
The nuclear file remains unresolved. The memorandum of understanding calls for Iran to, at minimum, dilute its stockpile of highly enriched uranium under International Atomic Energy Agency supervision. But major questions remain over whether Iran will be allowed to enrich uranium in the future and how inspectors would verify compliance.
Vice President JD Vance attended the talks alongside U.S. envoys Steve Witkoff and Jared Kushner. Vance has said the Trump administration wants to use the process to open a new chapter with Iran, but the White House is also trying to maintain pressure through threats of force.
That mixed message may define the next phase. Supporters of the talks say the 60-day roadmap is the best chance to prevent another war and stabilize oil routes. Critics warn that Iran may gain economic relief before giving enough firm concessions on nuclear and regional security issues.
For now, the first day ended with enough progress to keep negotiations alive. But the hardest issues — Lebanon, uranium enrichment, inspections and sanctions relief — are still ahead.
Why It Matters
The talks matter because they could determine whether the U.S.-Iran framework becomes a real agreement or collapses under regional pressure. Progress on Hormuz and Lebanon could stabilize energy markets and reduce the risk of wider war, while failure could return both sides to military confrontation.
What Comes Next
Technical teams will continue talks in Switzerland through the week. Negotiators are expected to focus on nuclear verification, sanctions waivers, frozen assets, the Strait of Hormuz communication line and the Lebanon de-confliction mechanism.
