Iran has rejected Oman's proposal for a 50-50 joint oversight mechanism of the critical Strait of Hormuz, instead submitting its own counterproposal. Iran's Deputy Foreign Minister Kazem Gharibabadi stated that Tehran's plan would grant it significantly more control over the waterway, managing shipping through its side of the strait and part of the opposite lane. The Strait of Hormuz, through which about one-fifth of the world's oil and LNG supplies passed before recent conflicts, was previously closed by Iran, triggering global supply challenges. Diplomatic discussions continue amidst disagreements over control and shipping fees, with Iran warning the strait will remain closed if its plan is rejected.
