A planned meeting between Iran and Gulf countries in Oman was canceled after Saudi Arabia objected, Iran’s foreign ministry spokesman said. The meeting formed part of diplomatic efforts involving the Strait of Hormuz, a vital global oil-shipping route, amid tensions linked to the Iran–U.S. situation. The cancellation underscores divisions among Gulf states over engagement with Iran and represents a setback for regional diplomacy. Market pricing suggests the development could reduce the likelihood of a U.S.-Iran diplomatic meeting by the Sept. 30, 2026, deadline. Observers are expected to focus on official statements from Iran, Saudi Arabia and Oman, as well as changes in the U.S.-Iran relationship and announcements of new meetings.
