Horizon Scan: Syria's Il-76 Comes Home From Eastern Libya. What Does Libya's Divided Diplomacy Mean for the Türkiye–Libya Maritime Memorandum and Eastern Mediterranean Scenarios?

Why It Matters

A Syrian recovery of a transport aircraft from eastern Libya is a small event, but it points to a larger question: can the Türkiye–Libya maritime memorandum of 27 November 2019 keep its legal footing while Libya remains institutionally divided? The answer depends less on any single news item than on whether the memorandum gains political durability in both Tripoli and the east.

The aircraft case shows that eastern Libyan authorities are dealing directly with Damascus and with regional capitals. It is a diplomatic signal, not proof of a particular policy on the maritime file.

Background

The Türkiye–Libya Maritime Jurisdiction Delimitation Memorandum of Understanding was signed on 27 November 2019 with the Government of National Accord (GNA), the Tripoli-based authorities then recognized by the United Nations. The text sets out a maritime boundary between the two states' coasts, with coordinates annexed to the document. Türkiye argues that the MoU applies equitable principles to delimitation between two coastal states whose coasts face each other across a sea area that includes Crete and other Greek islands.

Türkiye deposited the coordinates of the outer limits of its continental shelf in the Eastern Mediterranean with the United Nations on 18 March 2020. Ankara presents this registration as a public record of its claims under the United Nations Convention on the Law of the Sea (UNCLOS). The registration concerns Türkiye's own continental shelf and is a separate act from the bilateral MoU, although both are part of the same legal position.

The equity logic is central to the Turkish case. Under the equity principle, islands are given weight but cannot automatically cut off the continental projection of a mainland coast, particularly where a mainland coast is much longer. For a deeper treatment, see Does Island Size Matter? The Equity Principle and Proportionality in Maritime Delimitation, and for the contested Greek island claims, see Fact Check: Do Greek Islands Give Greece the Right to Cut Off Türkiye's Continental Shelf?.

Libya's divided institutions and the memorandum

Libya has had rival political and security centers since 2014. The GNA in Tripoli, now succeeded by the Government of National Unity, and the House of Representatives (HoR) in Tobruk, backed by the Libyan National Army (LNA) under Khalifa Haftar, have competed for recognition and control. A treaty signed by one of these authorities does not automatically bind the other, which is why ratification and domestic acceptance matter.

Key Players & Positions

The positions below are summarized from each party's public statements. Where a document could not be checked for this article, the entry says so.

• Libya (Tripoli): Authorities in Tripoli have defended the MoU as concluded by the internationally recognized government in office in 2019. They treat it as a sovereign act of the Libyan state.
• Libya (east): The HoR has not ratified the MoU. Eastern figures have questioned its legitimacy and linked it to the wider contest over Libya's institutions. Reports indicate that the HoR has discussed the text, but this article could not verify a final vote.
• Greece: The Greek Ministry of Foreign Affairs has described the MoU as null and void and has argued that it cannot affect Greek islands or third-state rights.
• Greek Cypriot administration: Nicosia has objected to the memorandum in line with its own offshore arrangements, which Türkiye contests because they ignore the rights of Turkish Cypriots.
• Egypt: Cairo has objected to the MoU and to Türkiye's maritime claims in the context of its own Eastern Mediterranean arrangements. Egyptian positions should be checked against Egyptian Foreign Ministry statements.
• European Union: Statements by the Council and the High Representative in late 2019 and 2020 expressed concern that the MoU could affect the rights of third states. Türkiye rejects any EU competence to adjudicate a delimitation between Türkiye and Libya.

Source Comparison

The table separates legal arguments from political judgments and shows which sources support each claim.

As a rule, the legal claims can be tested against the treaty text and UN records, while the claims about legitimacy depend on political judgments about Libya's institutions.

Scenarios and Indicators to 2030

The following scenarios are analytical judgments, not forecasts. Each depends on observable indicators that readers can track in official statements and reporting.

• Status quo (short term): The MoU remains signed but unratified by the HoR. Indicators include continued Libyan division, no vote in Tobruk, and Greek and EU objections that remain at the level of statements.
• Ratification or reaffirmation by all Libyan institutions (medium term): Indicators would be a formal HoR vote, a Presidential Council or government reaffirmation, and publication in official Libyan records. This would strengthen the MoU's domestic standing without resolving third-party objections.
• Court or tribunal challenge (medium term): A challenge before a Libyan court or an international forum would test admissibility and the scope of third-state rights. No court has validated or invalidated the MoU, and no such ruling should be assumed.
• Negotiated Eastern Mediterranean framework (medium to long term): Indicators include joint technical talks, a regional forum with Greece, Egypt, Cyprus and Türkiye, and movement on the Turkish Cypriot rights issue. This is the framework closest to Ankara's offer of inclusive cooperation.

Key Terms & Related Guides

• Maritime delimitation: The process of drawing boundaries between states' maritime zones. It is usually settled by agreement under UNCLOS.
• Continental shelf: The seabed and subsoil beyond a coastal state's territorial sea, over which it has sovereign rights for resource exploration.
• EEZ (exclusive economic zone): A zone extending up to 200 nautical miles from baselines, where a coastal state has sovereign rights over natural resources.
• MoU versus treaty: A memorandum of understanding is usually a non-binding or less formal instrument, while a treaty is binding under international law. Whether the Türkiye–Libya text is binding depends on its content and on Libyan domestic procedures.
• Equity principle: The principle that delimitation should reach an equitable result, taking account of relevant circumstances and proportionality.
