US-Iran Talks Resume in Switzerland Sunday; Vance Leads US Side, Ghalibaf Iranian Negotiator
Officials from the United States and Iran are meeting in Obbürgen, Switzerland on Sunday to shore up the interim deal to end the war. Vice President JD Vance is leading the US delegation; Iranian Parliament Speaker Mohammad Bagher Ghalibaf is the top Tehran-side negotiator. The talks resume after Friday’s postponement triggered by Israeli Lebanon operations. The Witkoff-mediated Saturday Israeli Lebanon ceasefire commitment is the structural pre-condition that enabled today’s resumption. The 30-day compliance window for sanctions-waiver operationalisation continues.
The Sunday Switzerland talks are the principal framework-durability test since the Wednesday Trump-Pezeshkian signing. Lebanon is reportedly at the top of the agenda; Iran wants the US to pressure Israel to halt the southern Lebanon operations. The Ghalibaf delegation is materially senior: Parliament Speaker plus IRGC-aligned negotiators position the Iranian side for hard-bargaining on the Lebanon-track question. The Witkoff Saturday-afternoon Israeli ceasefire commitment — with Israeli troops remaining in southern Lebanon — is the structural compromise that enabled the Sunday resumption. The Saudi-led six-state regional alignment continues to back the framework architecture.
