Araghchi was likely responding to a Monday interview where US President Donald Trump threatened Iran, saying, "We're going to make a deal, or we're going to finish the job."

Iran's Foreign Minister Abbas Araghchi warned in a post on X/Twitter on Tuesday that "negotiations on a final deal will not commence" if threats by the United States continue.

He claimed that "Para 13 of the Memorandum of Understanding (MoU) is clear. Negotiations on final Deal (sic) will not commence if threats continue."

"Honor your signature," he added.

Para 13 of the MoU states that the signatories (the US and Iran) are committed to and subject to implementing a ceasefire, lifting the blockade of the Strait of Hormuz, waiving sanctions, and unfreezing restricted assets.
