In 1976, Sri Lanka legally defined the concept of EEZ in the "Maritime Zones Law, No. 22 of 1976".

 * 2) The contention of the territorial sea and the contiguous zone.
 * 3) The convention on the Continental Shelf.

Between 1974 and 1976, the India–Sri Lanka maritime boundary agreements were signed and define the international maritime boundary between the two countries. In 1982, Sri Lanka was an active member in the third Third United Nations Conference on the Law of the Sea (UNCLOS III) proclaiming her Maritime Zones. Sri Lanka has petitioned United Nations based on scientific and other data to extend its EEZ beyond the current 200 Nautical miles.
