Greece Targets Turkey-Libya Sea Deal

The most important boundary dispute in the Eastern Mediterranean is being fought through coordinates, not soldiers. On 27 July, Greek and Libyan delegations finished a third round of technical talks in Athens, comparing legal arguments over where their maritime zones meet south of Crete (ERT, ProtoThema). The meetings sound procedural. The purpose is strategic. Athens wants a maritime boundary with Libya that weakens the 2019 Turkey-Libya memorandum, the deal that effectively drew Greek islands out of the Eastern Mediterranean map.

The plan is legally coherent. Its weak point is political: Greece needs Libya to act like a state capable of speaking with one voice.

The memorandum Crete can't afford

In November 2019, Turkey and Libya's Tripoli-based government signed a memorandum treating their coasts as if they directly faced each other. The line they drew gave Greek islands, especially Crete, almost no maritime weight. Under the UN Convention on the Law of the Sea, the main treaty governing maritime boundaries, islands normally generate the same offshore zones as mainland coastlines unless they are uninhabitable rocks (UNCLOS). Crete is large, populated, and central to the geography of the area. The memorandum treats it as a detail.

EU leaders rejected the deal within weeks. The European Council, where heads of state and government set the EU's political direction, said it infringed the sovereign rights of third states and could not bind countries that were not party to it (European Council). But a political rejection does not erase a document from Ankara's diplomatic arsenal. Without a competing agreement, the memorandum remains part of Turkey's case for jurisdiction south of Crete.

Greece's strategy and its weakest link

Greece's answer is slow and technical: bring Libya into a separate bilateral delimitation south of Crete. If Athens and Libya agree their own line, Ankara will find it harder to present the 2019 memorandum as the only existing arrangement.

The problem lies inside Libya. Since 2014, the country has been split between rival governments. The eastern-based House of Representatives reportedly never ratified the 2019 memorandum with Turkey, leaving its domestic legal status contested before international law is even considered (Ahram Weekly). Greece needs these rival Libyan institutions to remain engaged long enough to produce coordinates that could underpin a treaty or, later, a case at the International Court of Justice.

A joint technical committee held a second round in Tripoli on 10 June before meeting again in Athens. According to the Greek readout, the talks have not yet produced agreed coordinates or a draft agreement (ERT).

Turkey's legal position is more specific than the public argument often suggests. Ankara does not say that islands never count. It argues that international courts have sometimes reduced the maritime effect of islands when giving them full weight would distort the overall boundary. That argument has some basis in case law (ICJ Libya/Malta, Daily Sabah). But reducing an island's effect is not the same as erasing it. The 2019 memorandum comes much closer to erasure.

Why Rome and Nicosia are watching

Italy looks at Libya through energy and migration. The GreenStream pipeline links Libyan gas fields to Sicily, and Italian Defence Minister Guido Crosetto and Foreign Minister Antonio Tajani have framed stability in the southern Mediterranean as a direct economic interest (Formiche). That matters for Malta too. Instability in Libya is not an abstract regional concern from Il-Belt; it has repeatedly reached Maltese shores through migration pressure, energy calculations, and diplomacy with Rome.

Cyprus has the sharpest exposure. European energy companies are developing offshore gas fields in Cypriot waters, with production targeted from 2028 (Phileleftheros). If Turkey's map gains legitimacy in one part of the Eastern Mediterranean, Nicosia's offshore claims become easier to challenge elsewhere. Turkey has also backed the memorandum with a military presence in Libya, which makes the 2019 deal harder to displace by legal drafting alone (Les Clés du Moyen-Orient).

Athens, which is simultaneously blocking the EU's latest Russia sanctions package to protect its shipping sector, is betting that patient map-making can outlast a political memorandum. For now, Greece has a legal strategy whose weakest point is the state it needs on the other side of the table.
