Turkey and Libya on Thursday declared a recent agreement signed between Greece and Egypt on the delimitation of maritime jurisdictions in the Eastern Mediterranean "null and void," stressing that the deal usurped and ignored the rights and continental shelves of both Ankara and Tripoli.

Foreign Minister Mevlüt Çavuşoğlu late Thursday indicated that the text and map of the agreement had yet to be revealed, adding: "However, it's obvious by the given coordinates that the deal not only violates the rights and continental shelf of Turkey but also of Libya."

"Hence, an agreement that violates our continental shelf, which we have reported to the U.N., is null and void and the reason why we've come to this point is that countries like Greece and the Greek Cypriot administration, are trying to sign agreements with Egypt and Israel while ignoring Turkey," Çavuşoğlu told Anadolu Agency (AA).

"We'll continue to show them and the world that this agreement is null and void on the table and in the field," the minister stated.

Turkey’s statements were followed by the official Libyan government which similarly condemned the Greek-Egyptian deal.

"Libya will not allow violations of its maritime rights," foreign ministry spokesman Mohammed al-Qablawi said on Twitter. Al-Qablawi reiterated Libya's commitment to a memorandum of understanding concerning the delimitation of maritime jurisdiction signed with Turkey. Libya urges states bordering the Mediterranean to act in accord with the principles of international law, al-Qablawi also stressed.

The Turkish Foreign Ministry in a written statement on the same day elaborated that there is no mutual sea border between Egypt and Greece. It reminded that Egypt, which surrendered an area of 11,500 square kilometers (4,440 square miles) with the so-called agreement it signed with the Greek Cypriot administration in 2003, has once again acted at the expense of and against the interests of the Egyptian people with this move.

Ankara also said that Turkey will not allow such activities in the area and reiterated the country’s determination to protect both Turkey’s and Turkish Cypriots’ legitimate rights and interests in the Eastern Mediterranean.

Greece: maritime deal ‘legitimate’

Egypt on Thursday announced that it had signed a bilateral agreement with Greece on the "delimitation of maritime jurisdictions" between the two countries.

Speaking at a joint press conference in the capital Cairo with his Greek counterpart Nikos Dendias, Egyptian Foreign Minister Sameh Shoukry said the deal "opens new horizons for economic cooperation with Greece."

Dendias, for his part, said the maritime agreement with Cairo was "legitimate" and "reflects the dimensions of cooperation between the two countries in combating threats in the region."

Greece accordingly said Thursday the deal on exclusive economic zones (EEZ) in the Eastern Mediterranean is "in accordance with international law." Greek Prime Minister Kyriakos Mitsotakis said the deal is "a legitimate agreement that fully satisfies both countries."

Since the discovery of significant gas reserves in the region a decade ago, countries have been engaged in renewed disputes over maritime borders while international law also presents few remedies. The deepening rift between the two countries has surfaced with Turkey’s decision to enhance energy exploration activities in the Eastern Mediterranean and the deal Ankara made with Libya’s official government.

Egypt and Greece are at odds with Turkey, which last year angered the two countries by signing a maritime delimitation agreement with the internationally recognized Libyan government, in a move that escalated disputes over potential offshore gas reserves in the Eastern Mediterranean.

The countries had been in talks for a while after Turkey and Libya on Nov. 27, 2019, signed two separate pacts – one on military cooperation and the other on maritime boundaries of countries in the Eastern Mediterranean.

The agreement between Turkey and Libya determined the sovereignty area based on international law as 186,000 square kilometers. Thus, the possibility of making an EEZ agreement between Greece and Egypt, and Greece and Greek Cyprus, was eliminated.

The maritime pact asserted Turkey's rights in the Eastern Mediterranean in the face of unilateral drilling by the Greek Cypriot administration, clarifying that the Turkish Republic of Northern Cyprus (TRNC) also had rights to the resources in the area. The pact took effect on Dec. 8.

Within this scope, Ankara has sent drilling vessels to the Eastern Mediterranean since last year, a move opposed by Athens and the Greek Cypriot administration which have threatened to arrest the ships' crews and enlist European Union leaders to join their criticism.

Ankara has on every occasion vowed it wants to see energy as an incentive for political resolution on the island and peace in the wider Mediterranean basin, not a catalyst for further tensions. Yet, Egypt and Greece condemned the deal as "illegal" and a violation of international law.

Tensions were already high between Greece and Turkey because of Turkish gas exploration in the Eastern Mediterranean off the coast of the island of Cyprus. The NATO members are also at odds over mineral rights in the Aegean Sea.

Turkey has the longest shoreline in the Eastern Mediterranean, making it a natural candidate for seeking reserves in the region in accordance with international law. The presence of the Turkish Cypriot government in Northern Cyprus also strengthens Turkey's hands as the country defends the rights of the Turkish Cypriots in the region and insists that their consent is needed for any type of drilling activities.
