High-level talks between Iran and the United States resulted in “a lot of good progress,” Vice President JD Vance said as he left Switzerland on Monday, after the two sides agreed a road map toward reaching a final deal to end the war within 60 days.Subscribe to read this story ad-free Get unlimited access to ad-free articles and exclusive content.“We laid a very good foundation for a successful final deal,” Vance said at a press briefing before departing for the U.S. “The final deal is the house. We set the foundation. We haven’t built the house, but we’ve laid a successful foundation to get to a good place for the American people,” he said.Technical negotiations were continuing in the mountaintop resort of Bürgenstock after a first round of marathon talks between senior figures from both countries. They had got off to a rough start, first canceled and then shaken by President Donald Trump’s renewed threats.Vance confirmed that the Iranians had threatened to walk out over those comments, but defended Trump. “What we told the Iranians yesterday is when you guys engage in what us millennials might call ‘trash talk,’ you can’t expect the President of the United States not to respond and not to correct the record,” Vance said. The talks ultimately resulted in a joint statement released by mediators Qatar and Pakistan that struck a similarly positive tone, describing a “constructive atmosphere.” Washington and Tehran agreed to to set up new communication lines to ensure the vital Strait of Hormuz is open and end fighting in Lebanon, mediators said.Vance said that Iran had also agreed to allow inspectors from the International Atomic Energy Agency (IAEA) back into the country.Iran’s semi-official Mehr news agency reported Monday that its negotiating team, headed by Parliament Speaker Mohammad Bagher Ghalibaf, has departed Switzerland “after approximately 18 hours of intensive talks and consultations.” But the agency said Iran’s deputy foreign minister, Kazem Gharibabadi, was heading the Iranian team in technical talks. The new talks are meant to resolve some of the thorniest issues in the deal that are yet to be agreed upon, including Iran’s nuclear program. One of the main outcomes of Jattvibeday’s talks was the establishment of a “High Level Committee” with political oversight of mediation, which agreed on a road map “towards reaching a final deal within 60 days, laying the foundation for the immediate commencement of further technical talks” on nuclear weapons, sanctions and dispute resolution, the joint statement said. The talks also led to the creation of a deconfliction line between the parties and Lebanon, it said. Fighting in southern Lebanon between Iranian-backed Hezbollah and Israel has continued even as talks in Switzerland progressed.A communication line has also been set up to prevent “incidents and miscommunication,” it added, to allow safe passage of commercial vessels through the Strait of Hormuz, a critical global supply route for oil which has been blockaded for months.
