US Vice President JD Vance said talks with Iranian officials in Switzerland had laid a good foundation for a final peace deal, although Iran denied that it had begun discussions of its nuclear programme.

Trump said in a post ​on Truth Social on Monday that Iran ⁠will agree to have weapons inspections to ensure “nuclear honesty.”

“If Iran doesn’t live up to their agreement, or if they’re not behaving, I will do what I have to do,” Trump later told reporters.

Iran has limited inspections by the International Atomic Energy Agency since the US and Israel launched ​a first round of air strikes last year, and suspended them entirely when war broke out in February.

It says its nuclear programme ​is peaceful.

Vance said White House envoy Jared Kushner, Trump’s son-in-law, had come up with a process whereby the US and Qatar would have control over Iranian funds when they are unfrozen, and the money ⁠could be ​spent on US corn, soy and wheat.

“So, the money that we lift is going to go to our farmers,” ​Trump told reporters.

However, Iran’s Central Bank Governor Abdolnaser Hemmati said there was no such obligation and said at least some of the remaining frozen funds could be used to buy other non-sanctioned goods, Iran’s Tasnim news agency reported.
