US-Iran talks conclude in Switzerland amid US threats and Iranian delegation walkout; upcoming technical talks a critical juncture: Chinese expert

On June 22, 2026, the US and Iran concluded high-level talks in Switzerland, mediators said. The two sides agreed on a 60-day path to an agreement and launched mechanisms for Lebanon and Hormuz. Vance said Iran agreed to invite IAEA inspectors back and that unfrozen funds would not fund terrorism. TASS wrote that the Iranian delegation left Switzerland after 18 hours of talks, and Global Times headlined its piece with a mention of US threats and a delegation walkout.

Technical talks between the two sides were to continue in Switzerland, and Iran confirmed their start. Pakistan's PM Shehbaz and CDF Munir met Vance and the Iranian delegation. On Lebanon, Aoun discussed ceasefire efforts with Vance in a phone call, and the US set up a 'monitoring mechanism' for the fighting, with three days of new direct talks due to start the next day.
