Iran and Oman, as the two coastal states bordering the Strait of Hormuz, have advanced bilateral talks on navigation routes, maritime services, and security arrangements since mid-2026, including a June joint working group and August-September frameworks for temporary corridors and joint mine clearance. Progress centers on proposals granting Iran primary oversight of inbound lanes near its waters while sharing some outbound segments and revenues, after rejecting equal-division models. Implementation stays linked to US policy steps on sanctions, blockades, and prior memoranda, with recent statements noting maps and statements ready for International Maritime Organization review. Further technical negotiations and regional consultations could shape outcomes before any permanent administration deal.
