Fortunately, the governments of Indonesia, Malaysia, and the Philippines are working independently, tri-laterally, and with international partners to provide stronger maritime governance in the Sulu and Celebes region. The establishment of the Trilateral Cooperative Agreement in 2016 was an important step toward overcoming regional tensions and instilling new efforts to address maritime crimes like piracy and armed robbery at sea. As of early 2019, these initiatives are being further strengthened with the establishment of a Contact Group on Maritime Crime in the Sulu and Celebes Seas. Drawing from experiences with the Contact Group on Piracy off the Coast of Somalia, this new group, initiated by the United Nations Office on Drugs and Crime (UNODC), brings in international partners to foster regional cooperation and advance the shared goal of securing these seas for the economic and physical welfare of coastal populations and the safe and sustainable development of the regional "blue economy."Stable Seas: Sulu and Celebes Seas is an effort to contribute to these positive developments through rigorous and politically impartial research on this complex maritime region.
