US Vice President JD Vance announced on Sunday that he plans to attend the signing ceremony of a peace agreement with Iran in Switzerland within a few days, indicating that President Donald Trump may also participate.

Responding to a question from Fox News about whether he would attend the signing ceremony that Pakistan, acting as mediator, said would be held in Geneva on 19 June, Vance said: "I certainly plan to be there, but it's possible that the President himself will be there."
