The conclusion of the Law of the Sea Convention in 1982 (Convention), highlighted by the emergence of a new maritime zone and the extension of the breadth of territorial sea from three to twelve nautical miles, has required Indonesia to adjust its maritime boundaries. As any other coastal state, Indonesia is entitled to all maritime zones as provided by the Convention and therefore needs to draw the boundaries for the respective zone in accordance with its provisions. Geographically, Indonesia is bordered by ten neighboring states where the maritime zones overlap. As prescribed by the Convention, Indonesia shall enter into negotiation with its neighbors to reach an agreement. This Article will explain how Indonesia addresses the issue.
