A crisis over the Yemeni island of Socotra was resolved this week, as the United Arab Emirates agreed to withdraw and turn control over to Saudi forces, which will in turn restore full Yemeni rule there. The island, just off the very tip of the Horn of Africa, has been ruled by Yemeni governments for centuries between periodic episodes of control by various European powers, and is today a UNESCO World Heritage Site for its unique flora and fauna, hailed as the "Galapagos of the Indian Ocean." Emirati forces seized it at the beginning of the month, and raised their flag over the airport and other strategic points—sparking angry protests from the island's inhabitants. Hashim Saad al-Saqatri, Socotra's governor, condemned the UAE move as an "occupation," saying it represented "a flagrant violation of Yemeni sovereignty." Even after the de-escalation, suspicions remain. Yemen's ambassador to UNESCO, Ahmad al-Sayyad, charged that "there is synergy between the roles of Saudi Arabia and the UAE. There is a hidden inclination to divide Yemen." (Middle East Eye, May 18; Al Jazeera, May 17)

Saudi Arabia and the UAE are the central pillars of an international coalition backing up Yemen's official government, now based in the port of Aden, against Houthi rebels who have held the capital Sanaa since 2014. Proposals to break Yemen into  autonomous districts  as a solution to its administrative dilemmas have been rejected as masking annexationist ambitions by Saudi Arabia and other regional powers.
