Regarding the report by the US State Department, which was forwarded to the US Congress on March 18 and in the framework of the provisions of the "Eastern Mediterranean Security and Energy Partnership Act," diplomatic sources pointed out that the borders of Greece's territorial waters, as well as the maritime borders between Greece and Turkey, have been clearly defined for years on the basis of international law and are not in any dispute.
In particular, they stated in response to the State Department that regarding the Southeastern Aegean and the Eastern Mediterranean, the maritime borders have been defined by the Italy-Turkey Agreement signed in Ankara on 4 January 1932, as well as the minutes which was signed in Ankara on December 28, 1932.
Greece, as the successor state under the Treaty of Paris of 1947, gained sovereignty over the Dodecanese without any change in the maritime borders, as agreed between Italy and Turkey.
Regarding the sea borders in Thrace (up to the point of a distance of three nautical miles from the Evros Delta), they emphasise that these were defined by the Treaty of Lausanne of 1923 and the Athens Protocol of 1926.
Finally, regarding the sea borders between the above two areas (from Thrace to Dodecanese), where the territorial waters of Greece and Turkey intersect, they pointed out that the sea borders follow the middle line between the Greek islands and islets and the opposite Turkish coasts.
The same diplomatic sources noted that Greece's external borders, including its territorial waters, are at the same time the external borders of the European Union.
The recently released State Department report states that Greece claims an airspace that extends up to 10 nautical miles and a territorial sea of up to 6 nautical miles, but that "under international law, a country’s airspace coincides with its territorial sea."
"The US thus recognizes an airspace up to 6 nautical miles consistent with territorial sea. Greece and the US do not share a view on the extent of Greece’s airspace," the report said.
The State Department report adds that although Athens currently claims up to a 6-nautical-mile territorial sea in the Aegean, “Greece and its neighbors have not agreed on boundary delimitation in those areas where their lawful maritime entitlements overlap.”
“Lack of such delimitation means there is no clarity on the extent of Greece’s territorial sea and corresponding airspace in these areas rendering any assessment of total violations not feasible,” the report said.
The State Department report said Washington encourages Greece and Turkey “to resolve outstanding bilateral maritime boundary issues peacefully and in accordance with international law.”
