The United States and Iran signaled fresh progress in efforts to end the ongoing conflict, though major disagreements remain over Tehran’s enriched uranium stockpile and control of the Strait of Hormuz.
Secretary of State Marco Rubio said Thursday there were “good signs” in the negotiations but warned any agreement would become impossible if Iran moved to impose permanent tolls on shipping through the strategic waterway.
President Donald Trump also rejected reports of a proposed Iran-Oman payment system tied to Hormuz traffic, insisting the route must remain open and free for international commerce.

According to Iran’s semi-official ISNA news agency, Tehran believes the latest U.S. proposal has narrowed differences between the two sides. However, Iranian officials reportedly want Washington to abandon what they described as threats of renewed war.
The report said Iran’s enriched uranium stockpile remains another major sticking point. Reuters reported that Supreme Leader Ayatollah Mojtaba Khamenei ordered that near-weapons-grade uranium not be transferred abroad.
Meanwhile, the USS Abraham Lincoln carrier group remains deployed in the Arabian Sea as the U.S. continues enforcing its blockade on Iranian ports.
