President Donald Trump said Wednesday that Iran will not be permitted to enrich uranium under a developing agreement between the two countries, marking a significant shift after weeks of military escalation and diplomatic pressure.

In a post on Truth Social, Trump stated that the United States will work directly with Iran to remove enriched nuclear material from sites previously targeted in U.S. strikes, including facilities at Natanz, Fordow, and Esfahan. He said the material remains under close surveillance and has not been moved since the attacks, which were carried out as part of Operation Midnight Hammer earlier this year.

Trump also indicated that discussions are underway regarding potential tariff reductions and sanctions relief, noting that many elements of a broader agreement have already been settled. He described the framework as part of what he called a “productive” political shift in Iran and said negotiations are advancing toward a finalized deal.

The comments come one day after the United States and Iran agreed to a two-week ceasefire, narrowly avoiding further military action ahead of a deadline set by the White House. As part of the arrangement, Iran has reopened the Strait of Hormuz, a key global shipping route that carries a substantial portion of the world’s oil supply. Iranian Foreign Minister Abbas Araghchi confirmed that vessels will be allowed safe passage through the waterway during the ceasefire period.

Trump said the U.S. may also explore a joint venture with Iran to oversee and secure traffic through the strait, including the possibility of implementing transit fees. The proposal, which he described as a way to enhance security and stability in the region, would mark an unusual form of cooperation between the two nations.

According to Trump, the United States views Iran’s multi-point proposal as a workable foundation for continued negotiations. He said the temporary ceasefire is intended to give both sides time to finalize and implement a long-term agreement addressing nuclear activity, economic measures, and broader regional concerns.

The situation remains fluid, but the latest developments suggest a potential de-escalation in tensions alongside a shift toward structured diplomacy between Washington and Tehran.
