• Summary

This legal document contains the English version of the Treaty between the Republic of Indonesia and Malaysia relating to the Delimitation of the Territorial Seas of the Two Countries in the narrow part of the Straits of Malacca signed on 17 Mar 1970. The coordinates determining the “narrow part” of the Strait of Malacca are stated in the preamble of the Treaty. The agreed Territorial seas boundary between the two countries in the said area is a median line between their respective baselines (not archipelagic baseline yet), which constitutes straight lines connecting 8 points. The coordinates of those 8 points are provided in Article 1.2.a of the Treaty.

Notably, besides point 1 (the starting point) and point 6, all other points’ coordinates coincide with those of the continental shelves boundary between the two countries agreed in October 1969. For point 6, it is beyond the 12-nautical mile territorial sea baseline of Malaysia, and thus the Malaysian territorial sea boundary goes straight from point 5 to 7, while that of Indonesia goes through all points normally.
