For more than a decade, the states bordering the Eastern Mediterranean Sea have been in disagreement over the delineation of their maritime boundaries. The disagreements concern various parts of the region and create enormous political tension over energy-related activities. Ever since Egypt and the Greek Administration of Southern Cyprus (GASC) signed the very first delimitation agreement of the region, without securing Turkey’s involvement, Turkey has issued many official statements and carried out energy-related activities in the region. Based on the principle that maritime delimitation should be carried out to reach an equitable solution by taking all the relevant circumstances into account, Turkey has developed a comprehensive legal approach as to the maritime delimitation in the Eastern Mediterranean and even submitted a map to the UN to demonstrate Turkey’s claimed continental shelf and Exclusive Economic Zones (EEZ) areas. The details of this comprehensive approach should be examined, to identify both the claims of Turkey over the maritime borders and the related legal arguments.
