Turkey-Libya Maritime Deal Heightens Tensions in the Eastern Mediterranean

By Drooid · · How we work

The Agreement and Its Immediate Effects

Libya’s eastern parliament voted unanimously to approve a maritime memorandum with Turkey, creating a direct economic corridor linking Turkey’s southern coast to Libya’s northern shoreline. The pact, welcomed by Turkey’s Foreign Ministry, enables joint exploration of oil and gas deposits estimated at several hundred billion US dollars. The corridor runs across waters claimed by Greece, bypassing islands such as Crete, Karpathos and Rhodes.

Background and Legal Context

In 2019 Turkey signed a similar memorandum with the UN-recognised Government of National Accord (GNA) in western Libya and later cultivated ties with the eastern commander Khalifa Hifter’s camp. Greece bases its maritime claims on UNCLOS Article 121, citing the International Court of Justice’s 2022 Nicaragua-Colombia ruling as precedent. Turkey, which has not ratified UNCLOS, argues that granting full EEZs to every Greek island would block its access to the Mediterranean.

Official Positions

  • Turkey’s Foreign Ministry: Calls the agreement a legitimate step to secure economic rights over hydrocarbon resources.
  • Libyan Parliament (Eastern): Endorsed the memorandum as essential for Libya’s share of regional energy wealth.
  • Greek Government: Rejected the pact, asserting that Greece’s EEZ around its islands is comprehensive and that the agreement violates the Law of the Sea.
  • Israel’s Foreign Ministry: Condemned the deal as an infringement on the sovereign rights of Israel’s regional allies.

Points of Contention and Criticism

The dispute centers on the legal status of waters between Turkey, Libya and the Greek islands. Greece and the EU label the memorandum “null and void,” saying it breaches UNCLOS rights of third states. Turkey counters that Mediterranean geography requires a different delimitation approach and that the agreement reflects a “fair division” of resources. Maritime experts remain divided on an equitable boundary.

Strategic Implications

The corridor cuts across the planned route of the EastMed pipeline, intended to transport gas from Israel and Cyprus through Greece to the EU. Turkey argues that any subsea infrastructure on its claimed continental shelf requires its consent, potentially jeopardising the pipeline.

Analysts note the deal could solidify a bloc of Turkey and Libya, counterbalancing an EU-backed alliance of Greece, Cyprus, Egypt and Israel. Through the “Mavi Vatan” (Blue Homeland) initiative, Turkey seeks to limit Egypt and Russia’s influence in eastern Libya while securing energy fields.

Data and Statistics

  • Estimated natural-gas reserves beneath the disputed seabed: several hundred billion US dollars.
  • Joint seismic surveys are underway, coordinated by Turkey’s state-owned oil company TPAO and the Libyan National Oil Corporation.

Timeline of Key Developments

  • 2019 – Turkey signs a maritime memorandum with the GNA in western Libya.
  • 2022 – ICJ ruling in the Nicaragua-Colombia case reinforces fair maritime delimitation principles.
  • Recent Tuesday – Eastern Libyan parliament approves the new maritime agreement with Turkey.

What’s Next

  • Turkey and Libya plan offshore drilling in the corridor, likely prompting further diplomatic protests from Greece, Cyprus and the EU.
  • The EU may consider legal or political measures in response, though no deadline is set.
  • Negotiations over the EastMed pipeline’s route could be revisited as Turkey asserts consent rights over subsea infrastructure within its claimed shelf.
