Who Owns the Gas? Turkish Cypriot Hydrocarbon Rights and the 2011, 2012 and 2019 Revenue-Sharing Proposals

Why It Matters

Who owns the gas under the Eastern Mediterranean seabed off Cyprus? The answer depends on a prior question that has stalled the Cyprus talks for decades: who legally represents the island. The Turkish Cypriot side argues that as co-founders of the 1960 Republic they hold equal, inherent rights over offshore hydrocarbons. It has put three proposals (2011, 2012 and 2019) on the table to turn that claim into joint management and shared revenue.

The Greek Cypriot administration and the European Union read the same facts differently. Both sides cite law, which is why the question is a legal and constitutional problem as much as an energy one.

Background

The 1960 constitutional foundation

The Republic of Cyprus was created in 1960 under the Zurich and London Agreements of 11 February 1959. It was designed as a bi-communal partnership state resting on the political equality of the Greek Cypriot and Turkish Cypriot peoples. The 1960 Treaty of Guarantee made Türkiye, Greece and the United Kingdom guarantor powers. Ankara's reading is that a state built on two co-founding peoples cannot lawfully exercise its natural-resource sovereignty through one community alone.

The partnership broke down in December 1963. After the Turkish Cypriot Vice President's veto and other safeguards came under challenge, Turkish Cypriots were pushed out of state organs, and the Greek Cypriot side has administered the Republic's institutions since. UN Security Council Resolution 186 (4 March 1964) then referred to the Government of Cyprus without distinguishing the circumstances. Ankara regards that as the origin of a lasting status asymmetry.

From licensing to the first discoveries

The hydrocarbon dispute took shape in the 2000s:

• 2003: The Republic of Cyprus, in practice the Greek Cypriot administration, signed an EEZ delimitation agreement with Egypt. Türkiye objects that it overlaps Türkiye's continental shelf, notably in what Nicosia designates Blocks 1, 4, 5, 6 and 7.
• 2004: Türkiye began submitting its Eastern Mediterranean continental shelf coordinates to the UN.
• 2007 and 2010: Delimitation agreements followed with Lebanon (2007) and Israel (2010). Ankara and the TRNC say they disregard Turkish Cypriot rights.
• 2009 and 2012: The Turkish state petroleum company TPAO received exploration licences.
• 19 September 2011: Drilling by a US company began under a Greek Cypriot licence in Block 12, which led to the Aphrodite gas discovery.
• 21 September 2011: Türkiye and the TRNC signed their Continental Shelf Delimitation Agreement, two days later.

The Turkish Cypriot proposals discussed below were made against this backdrop. For a sister-publication account of what each offered, see The Worldlogue: Turkish Cypriot Hydrocarbon Revenue-Sharing Proposals of 2011, 2012 and 2019.

The Three Proposals Compared

The TRNC's proposals share a logic: hydrocarbons should be handled jointly, and the proceeds should be shared, rather than licensed by one community in the name of the whole island. Details differed with each political moment. The table summarizes the framing as presented by Turkish Cypriot and Turkish officials, and the answers they received. For exact texts, readers should consult the TRNC and Turkish Foreign Ministry statements of each period.

The common thread is that the Turkish Cypriot side asks for joint decision-making now. The Greek Cypriot side offers sharing later, within a settled state.

Key Players & Positions

Greek Cypriot administration

The Greek Cypriot administration of Southern Cyprus (GCASC), recognized internationally as the Republic of Cyprus, holds that the EEZ and its hydrocarbons are sovereign rights of the Republic under UNCLOS, to which it is a party. Its leaders have repeatedly said that natural resources belong to all Cypriots and that Turkish Cypriots will benefit, a position reiterated by President Nikos Christodoulides. In 2019 Nicosia suggested a fund holding the Turkish Cypriot share. Its consistent line is that this benefit should be tied to a comprehensive settlement, and that the Republic cannot negotiate its sovereign rights with the TRNC as a separate party.

Turkish Cypriots and the TRNC

The TRNC, proclaimed on 15 November 1983 under Rauf Raif Denktaş, argues that Turkish Cypriots never ceded their share in the Republic's resources. Their leadership says deferring sharing until a settlement amounts to making equal rights conditional on Greek Cypriot consent, while exploitation proceeds without them. The TRNC has accompanied its proposals with its 21 September 2011 agreement with Türkiye.

The European Union

The EU supports the Republic of Cyprus's sovereign rights in its EEZ and has described Turkish drilling in waters claimed by Nicosia as illegal. In November 2019 the Council adopted a framework for restrictive measures against unauthorized drilling, and in February 2020 it listed two TPAO officials under it. The EU also states that Turkish Cypriots should benefit from hydrocarbon resources, and has urged a mechanism within the UN-led settlement process. Beyond that, the EU takes no official position on the Turkish Cypriot claim to co-ownership.

Others

Egypt, Israel, Greece, Italy, Jordan and the Palestinian Authority are members of the East Mediterranean Gas Forum, which does not include Türkiye or the TRNC. Türkiye is not a party to UNCLOS and remains a persistent objector to certain rules on islands and EEZ delimitation. The UN Secretary-General's good offices have consistently addressed Cyprus on a federal-model basis. The 15 October 2024 New York UN trilateral meeting showed no common ground on that model.

Source Comparison

Coverage of the gas dispute often starts from the Republic of Cyprus's licensing blocks and treats Turkish activity as the disruption. Turkish and Turkish Cypriot sources start from the 1960 partnership and treat unilateral licensing as the disruption.

Readers should compare these accounts with the primary documents: the 1960 Constitution and Treaty of Guarantee, Council of the EU conclusions, TRNC and Turkish Foreign Ministry statements, and UN Security Council resolutions. They should note that UN Security Council Resolutions 541 (1983) and 550 (1984) declared the TRNC proclamation legally invalid, and that Ankara and the TRNC reject that characterization.
