Athens: The Turkey-Libya maritime deal moved from a contested memorandum to a ratified instrument on 20 October 2026, when Libya’s parliament approved it unanimously. The vote came a day before Turkish Foreign Minister Hakan Fidan sat down with EU High Representative Kaja Kallas in Brussels, which turned a bilateral text from 2019 into a live test of European diplomacy.
Kallas said the Turkey-Libya maritime deal infringes upon the sovereign rights of third states, and she added that she had raised it with Fidan alongside good neighbourly relations and the Cyprus settlement process. European Council President Antonio Costa and Commission President Ursula von der Leyen went further and called the ratification null and void and inconsistent with the law of the sea. Fidan made no public statement after the talks.
The legal quarrel is old, but the stakes are sharper now. Greece and Cyprus argue that islands such as Crete generate a full exclusive economic zone, while Ankara holds that islands are not entitled to one. The Turkey-Libya maritime deal fixes an EEZ boundary between two points southeast of Crete, which is exactly the stretch where Athens and Nicosia say the Turkish and Libyan claims cut across their own.
Ankara has answered with calm language that conceals little. After a cabinet meeting on 26 October, President Recep Tayyip Erdogan said Turkey was not trying to score a goal against anyone, and he described the Turkey-Libya maritime deal as a major step in guaranteeing the rights of Turkey and Libya. He also asked for the same constructive will from the EU, while warning that aggressive rhetoric detached from reality would benefit no one.
Brussels has tried to widen the circle of objectors. Greece read a joint statement at the United Nations on behalf of itself, Cyprus, Bahrain, Egypt, the United Arab Emirates and the EU, saying the agreement remains null and void and cannot serve as a lawful basis for maritime delimitation. Greek press also reported that the US State Department called the deal unconstructive and provocative. That coalition matters because it frames the dispute as a question of international law rather than a Greek-Turkish grievance.
The harder question is leverage. Kallas used the same meeting to stress shared ground, noting that the EU and Turkey both support a Black Sea freedom of navigation arrangement, and she pressed for shipping through the Strait of Hormuz to move without tolls or fees. Turkey is a NATO ally, a customs union partner and a Black Sea gatekeeper, so Brussels cannot afford a purely punitive response. Yet a statement of principle alone will not move Tripoli or Ankara.
A credible EU line would pair legal clarity with a diplomatic offer. The Union can keep its objection on record through joint statements and the Cyprus process, while inviting Ankara to talk about delimitation through arbitration or a bilateral track with Greece. Whether Erdogan’s call for dialogue with all coastal states is sincere will show in the coming weeks. For now, the Turkey-Libya maritime deal is the most concrete obstacle to any warming between Brussels and Ankara.
