Iran has moved to assert greater military authority over the Strait of Hormuz, a critical global trade artery, by announcing an expansion of its oversight area. Through the newly established Persian Gulf Strait Authority, the nation claims jurisdiction over more than 22,000 square kilometers, a move that encroaches upon the territorial waters of the United Arab Emirates and Oman. The new authority has declared that all vessels transiting the strait must now seek authorization and coordinate movements with Iranian officials, a mandate that has been flatly rejected by the United States and its regional allies.

Regional leaders have dismissed the claims as legally baseless. Anwar Gargash, a diplomatic adviser to the UAE president, characterized the move as an attempt to impose a new reality that lacks international legitimacy, labeling the territorial assertions as mere fantasies. While the United Nations Convention on the Law of the Sea guarantees safe passage for international shipping, Iran has notably not ratified the convention, further complicating the legal landscape of the region.

The situation remains volatile as both sides engage in maritime maneuvers. Recently, U.S. forces intercepted and boarded the oil tanker Celestial Sea in the Gulf of Oman, citing suspicions that the vessel was attempting to bypass an American blockade of Iranian ports. Meanwhile, the U.S. military continues to enforce its blockade, reporting the redirection of nearly 100 commercial ships since mid-April. Amidst these confrontations, diplomatic efforts are underway, with international mediators attempting to facilitate talks between Washington and Tehran to prevent further escalation.
