US President JD Vance declared Monday that a "very good foundation" had been laid for negotiations towards a final deal with Iran, after a marathon session of direct talks at a mountain-top resort Switzerland.
Tehran has agreed for inspectors from the UN's nuclear watchdog to return to the country, Vance said, a year after Iran suspended some cooperation and blocked inspectors from key nuclear sites bombed by the US and Israel in 2025's 12-day war.
