The Trump administration has told mediators it does not want to restore the terms of a memorandum of understanding reached with Iran in June, complicating efforts this week to restart diplomacy. President Trump signed the preliminary deal at the Palace of Versailles, with Vice President JD Vance helping negotiate it. The agreement aimed to reopen the Strait of Hormuz, resume talks on Iran's nuclear program and end the war, in return for sanctions relief (removal or easing of economic penalties) and access for Tehran to its frozen cash around the world. The arrangement collapsed within weeks after Iran began attacking ships to assert control over the vital waterway.
