**Diplomatic exchanges in September 2026 at the UN General Assembly renewed the longstanding UAE claim to Greater Tunb (alongside Lesser Tunb and Abu Musa), with Abu Dhabi calling for bilateral talks or referral to the International Court of Justice.** Iran immediately rejected these positions, describing sovereignty over the islands as complete, historical, and non-negotiable. Gulf Cooperation Council and Arab League statements have continued to back the UAE position, while Iran maintains an IRGC military presence, coastal defenses, and administrative control on Greater Tunb, which it has held since 1971. Recent U.S. strikes in mid-2026 targeted Iranian military assets on the island without altering on-the-ground authority. No scheduled events or negotiations indicate an imminent transfer of control, and the island’s position near the Strait of Hormuz reinforces its strategic value to Tehran. Trader assessments reflect these entrenched military and diplomatic realities.
