US and Iran talks in Switzerland move forward after brief walkout

The United States and Iran have made further progress in high-level talks in Switzerland, after a tense start that included a brief walkout by Iranian negotiators. According to the latest confirmed details, the two sides reached several key understandings during their first high-level session in the country. Those understandings include a 60-day timeline to finalise a deal, the creation of a High Level Committee to oversee the negotiations, and communication mechanisms for the Strait of Hormuz.

The talks were described as continuing after the initial disruption, with a US official saying discussions were expected to run into the early hours of Monday. Iranian Foreign Minister Seyed Abbas Araghchi said major progress had been made after the first session of technical talks, describing the process as the first real test. Tensions briefly rose when Donald Trump issued a sharp threat to the Iranian delegation over Hormuz before the negotiations resumed.

The Strait of Hormuz remains central to the talks because it is one of the world's most sensitive shipping routes and a key corridor for global energy flows. The reported communication mechanisms are intended to reduce the risk of incidents there, while the High Level Committee suggests the process is moving beyond a single meeting into a more structured negotiation track. The reported 60-day timeline also indicates that both sides are trying to set a defined window for progress, even as the wider political and security context remains fragile.

The Switzerland session is significant because it appears to be the first high-level round of talks in that setting, and it comes amid wider regional tensions. The reported focus on Hormuz shows that the negotiations are not limited to bilateral issues, but also touch on maritime security and the protection of commercial shipping. Any arrangement affecting the strait would have implications well beyond the two countries, given the route's importance for energy exports and international trade.

The talks also appear to be linked to broader efforts to reduce conflict in the region, with Araghchi referring to progress on ending the Lebanon war. That suggests the discussions are part of a wider diplomatic effort involving multiple security files rather than a single narrow agreement. The involvement of a high-level committee points to an attempt to keep the process moving after the initial breakthrough, while also managing the risks of breakdown.

What remains unclear is how the 60-day timeline will be enforced, who will sit on the High Level Committee, and how the communication mechanisms for the Strait of Hormuz will operate in practice. It is also not yet clear whether the reported understandings will hold through the next rounds of talks or whether further disputes will emerge. The negotiations are expected to continue, and any new statement from the parties will be closely watched for signs of either consolidation or renewed tension.

The United States and Iran have agreed a 60-day roadmap toward a final deal after the first round of talks in Burgenstock, Switzerland, according to a joint statement issued by mediators Pakistan and Qatar. The discussions were held at the Qatari-owned Swiss mountain resort and were aimed at permanently ending the war in the Middle East. Mediators said the parties also agreed to continue talks for the rest of the week.

The statement said the two sides will set up a communication line to avoid incidents in the Strait of Hormuz, one of the world's most sensitive shipping routes. It also said a so-called de-confliction cell would be created to help ensure safe passage for commercial ships through the contested strait. In addition, the parties agreed a mechanism intended to end the fighting in Lebanon, with Lebanon also to cease military operations.

Iran's foreign minister, Abbas Araghchi, said on social media that there had been major progress in the talks. He said oil and petrochemical exports would be waived, the blockade lifted, some frozen assets released, and a major reconstruction and development plan launched for Iran. The statement did not provide further detail on how those steps would be implemented or verified.

The agreement matters because the Strait of Hormuz is a critical route for global energy and commercial shipping, and any reduction in tension there could affect regional security and trade. The inclusion of Lebanon in the mechanism also suggests the talks are reaching beyond bilateral issues and into wider conflict management in the Middle East. The involvement of Pakistan and Qatar as mediators underlines the role of third parties in trying to keep the process moving.

US Vice President JD Vance began talks with Iranian officials on Sunday under the terms of a memorandum of understanding reached last week to extend a fragile ceasefire from April for at least another 60 days. The discussions continued until the early hours of Monday, according to the statement. That timeline suggests the current process is still at an early stage, even as the sides have now set out a framework for further negotiations.

What remains unclear is how quickly the roadmap can be turned into a binding final deal, and whether the proposed communication line and de-confliction cell will be put in place without delay. It is also not yet clear how the Lebanon mechanism will operate in practice or what enforcement would look like if either side falls short. The talks are due to continue through the week, and further statements from the mediators or the two governments are likely to be watched closely for signs of progress or disagreement.
