On May 28, two U.S. officials revealed that U.S. and Iranian negotiating representatives have reached a 60-day memorandum of understanding. The memorandum aims to extend the ceasefire and initiate negotiations on Iran's nuclear issue; however, President Trump has not yet given final approval. The signing of this memorandum would mark the most significant diplomatic breakthrough since the outbreak of conflict. To reach a final agreement that meets Trump's nuclear demands, both sides still need to engage in multiple rounds of intensive negotiations. U.S. officials stated that the terms of the agreement were essentially finalized by Tuesday, but both parties needed to seek higher-level approval at that time. U.S. officials indicated that Iran subsequently reported it had completed its internal approval and was ready to sign the agreement, although Iranian officials have not confirmed this. U.S. negotiating representatives have briefed Trump on all the details of the final agreement, and Trump has stated that he needs a few days to consider it. One U.S. official remarked, 'The President has informed the mediators that he wishes to take a few days to think this over.'
