US Vice-President J.D. Vance arrived in Switzerland on Sunday for high-stakes talks with Iran’s leadership as Tehran reiterated its closure of the Strait of Hormuz, raising tensions even as negotiators seek a fragile 60-day ceasefire framework. Vance landed in Zurich before dawn, joining a senior American delegation that includes US Special Envoy Steve Witkoff and Jared Kushner, the president’s son-in-law, for what both sides describe as a decisive phase in turning a wartime memorandum into a broader political settlement .
The Iranian delegation, led by parliament speaker and chief negotiator Mohammad Bagher Ghalibaf and foreign minister Abbas Araghchi, arrived in the Alpine resort of Bürgenstock on Saturday evening, according to multiple wire services . Before boarding his flight from Joint Base Andrews, Vance told reporters he expected progress on two fronts: Iran’s nuclear programme and a durable ceasefire in Lebanon, where fighting between Israel and Hizbollah flared again on Saturday despite a declared truce .
Tehran’s announcement that it had closed the Strait of Hormuz—through which roughly a fifth of the world’s seaborne oil passes—came hours after renewed Israeli strikes on Lebanon, which Iran said violated the ceasefire terms agreed in last week’s memorandum . The US has disputed Iran’s claim, with Vance telling journalists en route that Washington was focused on securing both the nuclear file and Lebanese stability .
The talks, convened in a luxury hotel outside Lucerne, follow a memorandum signed last week that established a 60-day window for negotiators to finalise technical details of a broader settlement. Both sides have framed the encounter as critical after weeks of stalled implementation, with mediators from Qatar and Pakistan also present to facilitate dialogue . Iranian state media reported that Ghalibaf and Araghchi held preparatory meetings on Saturday night, while Vance’s team arrived with a mandate to address both proliferation risks and regional de-escalation .
Analysts caution that the Hormuz dispute risks overshadowing progress, with the strait’s closure threatening global energy markets and complicating maritime security guarantees central to any nuclear deal. Yet diplomats in Burgenstock insist the structure of the talks—separated into technical and political tracks—offers the best chance in months to convert fragile understandings into enforceable commitments. Vance, who plans to stay only one or two days, has signalled cautious optimism, telling reporters that “we will hopefully make progress” on both the nuclear question and Lebanon’s ceasefire .
