Iranian media said on Sunday (May 17, 2026) that the United States had failed to make any concrete concessions in its latest response to Iran's proposed agenda for negotiations to end the war.

The Fars news agency said Washington had presented a five-point list which included a demand for Iran to keep only one nuclear site in operation and transfer its stockpile of highly enriched uranium to the United States.

The U.S. also refused to release "even 25%" of Iran's frozen assets abroad or pay any reparations for the damage inflicted on Iran during the war which broke out on February 28, according to Fars.

The report added that the U.S. had conditioned the cessation of hostilities on all fronts on the start of negotiations.

The Mehr news agency, meanwhile, said: "The United States, offering no tangible concessions, wants to obtain concessions that it failed to obtain during the war, which will lead to an impasse in the negotiations."

In its proposal, Iran had called for an end of the war on all fronts including Israel's campaign in Lebanon, as well as a halt to the U.S. naval blockade on Iranian ports in place since April 13.

It also called for lifting all of the U.S. sanctions and the release of Iranian assets frozen abroad under longstanding U.S. sanctions, according to the Iranian Foreign Ministry in a press conference last week.

Fars said the Iranian proposal had emphasised that Tehran would continue to manage the strategic Strait of Hormuz, a vital energy conduit which it has largely kept closed since the start of the war.

On Sunday (May 17, 2026), Iranian armed forces spokesman Abolfazl Shekarchi warned U.S. President Donald Trump against restarting attacks on Iran.

"The desperate American president should know that if his threats are carried out and Islamic Iran is attacked again, his country's resources and military will be confronted with unprecedented, offensive, surprising and tumultuous scenarios," he said, according to state television.

Similarly, Deputy Speaker of Parliament Hamidreza Hajibabaei warned against attacking Iranian oil infrastructure.

"If Iranian oil is harmed, Iran will take measures that will prevent the United States and the world from accessing oil from the region for an extended period," he said, according to the news agency ISNA.
