Diplomatic exchanges at the September 2026 UN General Assembly have renewed focus on the longstanding Greater Tunb dispute, with UAE representatives reiterating claims to the island alongside Lesser Tunb and Abu Musa and calling for bilateral talks or referral to the International Court of Justice. Iranian officials responded by affirming the islands as non-negotiable sovereign territory based on historical jurisdiction and continuous administration since 1971, rejecting any alteration to the status quo. Iran maintains military infrastructure and operational control on Greater Tunb, with no reported shifts in administration, shipping access, or physical presence amid broader Gulf tensions. These periodic statements reflect entrenched positions without triggering verifiable changes in effective control, leaving trader assessments anchored in the absence of military or diplomatic breakthroughs that could alter Iranian administration in the near term.
