The ongoing negotiations between the United States and Iran, mediated by Pakistan, are facing significant hurdles, primarily concerning control of the strategic Strait of Hormuz and the US demand for Iran to export its stockpile of highly enriched uranium. Pakistani Interior Minister Mohsen Naqvi has met with Iranian Foreign Minister Abbas Araghchi multiple times, aiming to secure a ceasefire. Iran is also seeking to postpone discussions on its nuclear program in favor of addressing hostilities and sanctions relief. Control over the Strait of Hormuz is a major point of contention, with Iran proposing the establishment of a Persian Gulf Strait Authority to manage maritime traffic, which five Gulf states have opposed, fearing it could lead to increased Iranian influence and toll imposition on vessels. US Secretary of State Marco Rubio has warned against Iran's plans, urging international rejection of any tolling system in the strait. Meanwhile, Iran's spokesperson has downplayed nuclear-related media speculation, focusing instead on broader peace negotiations. Russia has offered to assist with Iran's uranium stockpile, but Iran prefers to handle it domestically.
