Iran’s chief negotiator warned on Sunday (May 31, 2026) the United States was not to be trusted, saying Tehran would not agree to any deal with Washington unless it fully secured Iranian rights.

Mohammad Bagher Ghalibaf’s remarks came as reports emerged that US President Donald Trump had sent a tougher peace proposal back to Iran, and underlined the rift that the parties still need to close.

The New York Times and Axios reported that Mr. Trump had sent back a “tougher” new framework to be considered by Iran, though details remain unclear.

Mr. Trump has said his priorities include stopping Iran from developing any nuclear weapon and reopening the Hormuz shipping lane, which Iran has blockaded since the war began.

“The one guarantee that I have to have is that there will be no nuclear weapons. They’ve agreed to that, and it was very interesting,” he told his daughter-in-law Lara Trump in an interview on her Fox News show.
