East Indian Archipelago

The East Indian Archipelago is an area designated by the International Hydrographic Organization (IHO).

It encompasses twelve seas, two gulfs, and one strait in the East Indies (Southeast Asia).

The Sulu Sea, lying between the Philippines and Sabah (a state of Malaysia on the island of Borneo), is not in Indonesian waters.

Five countries have exclusive economic zones (EEZ) that extend into one or more of the five seas that are partially Indonesian.

Australia's EEZ extends into both the Timor and Arafura Seas and Papua New Guinea's EEZ extends into the Arafura Sea from its far southwest coast.
