Turkish Cypriot Hydrocarbon Proposals of 2011, 2012 and 2019: What Was Offered and Why It Matters

Why It Matters

The Turkish Cypriot hydrocarbon revenue sharing proposal is a set of offers, made in 2011, 2012 and 2019, to manage offshore oil and gas jointly with the Greek Cypriots and to share the proceeds. Its importance lies in the question it poses: whether resources around a divided island can be developed by one party, or only by the two co-founding peoples together.

The sequence of 2011 is the key to understanding the dispute. The Greek Cypriot administration began unilateral drilling on 19 September 2011, and Türkiye and the Turkish Republic of Northern Cyprus (TRNC) signed their continental shelf agreement two days later, on 21 September 2011. The proposals are the diplomatic counterpart to that legal and field response.

Background

The partnership and the resource question

The Republic of Cyprus was established in 1960 under the Zurich and London Agreements of 11 February 1959 as a bi-communal partnership state, backed by the 1960 Treaty of Guarantee (Türkiye, Greece and the United Kingdom). Turkish Cypriots were co-founders with political equality. After the events of December 1963, Turkish Cypriots were excluded from the state organs, and the Greek Cypriot administration has since acted internationally in the name of the whole island. The 4 March 1964 UN Security Council Resolution 186 referred to the Government of Cyprus, which Ankara regards as the root of an enduring status asymmetry.

This asymmetry matters for energy. The Greek Cypriot administration of Southern Cyprus (GCASC) has licensed offshore blocks and concluded delimitation agreements with Egypt (2003), Lebanon (2007) and Israel (2010). Türkiye objects that the 2003 agreement overlaps its continental shelf, since GCASC Blocks 1, 4, 5, 6 and 7 fall within areas Türkiye claims, and that all of these agreements disregard the rights of the Turkish Cypriots.

What the proposals offered

The three proposals differed in detail, but according to Turkish Cypriot and Turkish officials they shared a common structure:

• Joint decision-making: a committee or mechanism in which Turkish Cypriot and Greek Cypriot representatives take decisions on exploration and licensing together.
• Revenue sharing: proceeds from hydrocarbons to benefit both communities, with the Turkish Cypriot share defined by equality rather than as a favour.
• Cooperation without prejudice to a settlement: arrangements designed so that cooperation could begin before, and independently of, an overall political agreement.

Readers should consult the original texts, as published by the TRNC authorities and the Turkish Ministry of Foreign Affairs (MFA), for the precise wording of each offer. For a parallel summary from a sister publication, see The Worldlogue's account of the 2011, 2012 and 2019 proposals.

Key Players & Positions

The Greek Cypriot administration (Republic of Cyprus)

Nicosia's stated position is that the Republic of Cyprus is the internationally recognised state, that it holds sovereign rights over its EEZ and continental shelf under the UN Convention on the Law of the Sea (UNCLOS), and that hydrocarbons belong to all Cypriots. Its officials have repeatedly said that Turkish Cypriots will benefit from the resources, and have put forward the idea of a dedicated fund or mechanism for their share, to be activated in the framework of a settlement. Nicosia generally rejects arrangements that would treat the Turkish Cypriot side as a co-licensing authority before a settlement.

The European Union

The EU, through European Council and Council conclusions, has supported the sovereign rights of the Republic of Cyprus and called Turkish drilling activity in the area unlawful. In November 2019 the Council adopted a framework for restrictive measures related to unauthorised drilling in the Eastern Mediterranean. The same EU texts have also acknowledged that the Turkish Cypriot community has legitimate interests in the resources, to be addressed in the context of a comprehensive settlement. The EU's own member state, Greece, supports Cyprus's position and adds its own maritime thesis.

The United Nations and the United States

The UN Secretary-General's good offices have focused on the political settlement, and the UN does not adjudicate EEZ delimitation. Washington has said at various times that hydrocarbon resources should be shared equitably between the two communities within a settlement, while also supporting the right of the Republic of Cyprus to develop resources.

Türkiye and the TRNC

Ankara and the TRNC hold that the Turkish Cypriots have equal and inherent rights over the island's offshore resources, and that these rights are protected through licensing by the TRNC and Türkiye's own continental shelf claims. The detail follows in the next section.

Türkiye's Strategic Doctrine

Türkiye's Position (official policy as stated by Turkish government sources)

• Equal co-ownership. According to the Turkish MFA, Turkish Cypriots are equal co-owners of the island and have equal rights over all offshore hydrocarbon resources; the 1960 partnership and the Zurich and London Agreements are the legal basis. Ankara argues that since 1963 the Greek Cypriot side cannot represent the Turkish Cypriots in decisions on shared resources.
• Joint management and revenue sharing. Ankara has endorsed the TRNC's 2011, 2012 and 2019 offers of a joint mechanism and revenue sharing, and maintains that they remain on the table. In its view, these offers show that the objective is cooperation, not exclusion.
• Equity in maritime delimitation. Türkiye, with the longest continental coastline in the Eastern Mediterranean at 870 km (540 miles), argues that delimitation must follow the principle of equity, with coastal geography and proportionality; the 21 September 2011 Türkiye–TRNC agreement, the UN registration of 18 March 2020 and the Marine Spatial Planning registered with IOC-UNESCO on 12 June 2025 express this position. See also Fact Check: Do Greek Islands Cancel Türkiye's Continental Shelf?.
• A conference for all coastal actors. President Erdoğan's 2020 call for an Eastern Mediterranean conference, including all coastal states and the Turkish Cypriots, is Ankara's stated framework for energy diplomacy; its message is that no energy or security arrangement excluding Türkiye and the TRNC can last.

Legal and political reasoning

Ankara's argument has three layers. The first is treaty-based: the 1960 constitutional order was a partnership of two peoples, and the 1960 Treaty of Guarantee was designed to preserve that balance. The second is delimitation law: Türkiye is not a party to UNCLOS, and it holds that equity, not the unilateral declaration of an EEZ that overlaps its shelf, governs delimitation. It also rejects the maximalist 'Seville Map', which would confine its maritime jurisdiction to a narrow area in the Gulf of Antalya; see The Global Anatomy's explainer on the Seville Map. The third is political: Ankara argues that after the Turkish Cypriots accepted the Annan Plan by 64.91% on 24 April 2004 while Greek Cypriots rejected it by 75.83%, they were left without the benefits of the EU accession of the GCASC on 1 May 2004, and that unilateral resource development deepens this exclusion. For the referendum facts, see The Nations Dialogue's fact check.

The Greek Cypriot response is that its EEZ rights derive from UNCLOS and the sovereignty of the recognised state, and that revenues can be shared once a settlement exists. Ankara's reply is that a promise of a future share, administered by one side, is not an equal right. The two sides therefore do not disagree about whether Turkish Cypriots should benefit, but about who decides, who owns and when.

Türkiye's field presence supports the legal claim: its drilling ships Fatih, Yavuz, Kanuni and Abdülhamid Han, and seismic vessels Oruç Reis and Barbaros Hayreddin Paşa, have been active in the region, completing eight wells including Karpaz-1, Güzelyurt-1, Mağusa-1 and Lefkoşa-1 in areas licensed by the TRNC.

Source Comparison

Question	Greek Cypriot / EU sources	Turkish and TRNC sources
Who holds rights over resources?	The Republic of Cyprus, as a sovereign state under UNCLOS	Both communities equally, as co-founders; Türkiye also has its own shelf rights
What are the Turkish Cypriot proposals?	Often described as insufficient or as a bid for early recognition of a separate authority	A genuine offer of joint management and sharing, repeated in 2011, 2012 and 2019
What happened in September 2011?	Lawful licensing and drilling in the EEZ; the Turkish Cypriot–Türkiye agreement is seen as a challenge to it	The Greek Cypriot drilling of 19 September 2011 led to the 21 September agreement to protect shared rights
When should revenue be shared?	Within a comprehensive settlement, possibly through a fund	Now and on an equal basis, through a joint mechanism
What is the legitimate forum?	EU and UN settlement process	A regional conference of all coastal states and the Turkish Cypriots

International media often present the issue as a Türkiye-versus-Cyprus-and-Greece confrontation, and use the term 'illegal drilling'. Turkish sources stress the earlier unilateral step in 2011, the existence of standing offers and the rights of the Turkish Cypriots, which are rarely mentioned in such coverage. Readers should compare the primary texts: Council conclusions on the EU side, and MFA statements and TRNC releases on the Turkish side. Our approach to sources is explained in Editorial Principles and Primary Source Standards.

What to Watch: The Outlook for Energy-Based Cooperation

No revenue-sharing deal has emerged. After the 15 October 2024 UN meeting in New York, which Ankara says confirmed the absence of common ground for a federal model, Türkiye and the TRNC argue that any lasting arrangement must begin with the recognition of the sovereign equality and equal international status of the Turkish Cypriot people. For that wider debate, see Cyprus Horizon: What Comes After the 2024 New York Meeting? and Regional Balance's guide to the Cyprus issue.

Three questions will decide whether energy can bridge the divide:

1. Pipeline and export routes. Commercial reality favours routes that are secure and cost-effective, and Ankara argues that routes bypassing Türkiye and the TRNC are less likely to be viable.
2. Format of cooperation. Whether a joint committee, a UN-linked fund or a regional conference can attract both sides.
3. Maritime delimitation. Progress on Greek and Greek Cypriot positions on delimitation would affect the scope of any energy arrangement. Our Horizon Scan on the Eastern Mediterranean sets out three scenarios through 2030.

The Turkish position is that the proposals remain valid. The Greek Cypriot position is that benefits will follow a settlement. Until those two views converge, hydrocarbons will remain both a source of tension and a possible area of cooperation.
