Cyprus on the Horizon: What Comes After the 2024 New York Meeting and the End of the Federation Model?

Why It Matters

The 15 October 2024 informal meeting in New York did not restart formal Cyprus settlement negotiations, and the future of Cyprus talks now depends on a prior question: should any process begin from a federal blueprint or from the recognised equality of two peoples? The UN, the Greek Cypriot administration and the European Union answer “federation”; Türkiye and the Turkish Republic of Northern Cyprus (TRNC) answer “sovereign equality first, and two states.”

This guide sets out the factual record from 1959 to 2024, summarises each party's stated position from its own sources, and maps the diplomatic pathways that remain open. For readers following the wider maritime file, the energy dimension is covered in Horizon Scan: Where Is the Eastern Mediterranean Maritime Dispute Heading by 2030?.

Background

The Cyprus issue is a dispute over the legal nature of the 1960 state, the events of 1963 and 1974, and the status of the two peoples on the island. The facts below are widely documented; interpretations differ and are attributed in the sections that follow.

The 1959–1960 settlement and the Treaty of Guarantee

Ottoman rule lasted from 1571 to 1878, after which Britain administered the island; Türkiye recognised the British annexation in the 1923 Treaty of Lausanne. In the mid-1950s the EOKA organisation, founded in 1955 under Colonel Georgios Grivas, campaigned for ENOSIS (union with Greece). Turkish Cypriot sources record that Turkish Cypriots left some 33 mixed villages in 1955–1958.

The Zurich Agreement (11 February 1959) and the London Agreements (19 February 1959) produced the Republic of Cyprus, proclaimed on 16 August 1960. Its constitution was built on the political equality of the two communities: a Greek Cypriot President, a Turkish Cypriot Vice-President with veto powers, and community-based representation in the legislature and civil service.

The 1960 Treaty of Guarantee made Türkiye, Greece and the United Kingdom guarantor powers. Article I prohibits union with any other state or partition. Article IV provides that the guarantors consult in the event of a breach and, if concerted action is not possible, each reserves the right to act with the sole aim of re-establishing the state of affairs created by the treaty. Both clauses matter: Greek Cypriot and Greek sources emphasise the first, while Ankara relies on the second.

1963–1964: the breakdown and Resolution 186

On 30 November 1963 Archbishop Makarios proposed 13 constitutional amendments, including curbing the Vice-President's veto. Greek Cypriot accounts present them as measures to make government workable; Turkish and Turkish Cypriot sources view them as an attempt to reduce Turkish Cypriots to a minority. The Turkish side rejected them on 16 December 1963.

Intercommunal violence erupted on 21 December 1963 (“Bloody Christmas”). Turkish sources cite a Greek Cypriot planning document known as the Akritas Plan as evidence of premeditation. Turkish Cypriots withdrew from or were excluded from state organs, and about 30,000 were displaced from 103 villages, according to Turkish and Turkish Cypriot sources. On 30 December 1963 Nicosia was divided along the Green Line.

On 4 March 1964 UN Security Council Resolution 186 established UNFICYP and referred to the “Government of Cyprus” as responsible for law and order. Turkish Cypriots and Ankara argue that this wording gave one community's administration the status of the state and created the asymmetry that persists today. Greek Cypriot and most UN sources regard the resolution as recognising the continuity of the Republic of Cyprus.

1974 and 1983

On 15 July 1974 the Greek military junta and its Cypriot allies, including Nicos Sampson, staged a coup against Makarios. On 20 July 1974 Türkiye intervened, citing Article IV of the Treaty of Guarantee after consulting the United Kingdom. UN Security Council Resolution 353 called for the withdrawal of foreign military personnel. The island has been de facto divided since the second phase of operations in August 1974. A detailed legal reading of the intervention is provided by Borders & Blocs: Fact Check: Was Türkiye's 1974 Intervention in Cyprus Simply an 'Illegal Invasion'? What Article IV of the Treaty of Guarantee Says.

On 15 November 1983 Rauf Raif Denktaş proclaimed the TRNC. The UN Security Council, in Resolution 541 (1983), considered the declaration legally invalid and called for its withdrawal; Resolution 550 (1984) repeated that position. Only Türkiye recognises the TRNC. In 2022 the Organization of Turkic States granted the “Turkish Cypriot State” observer status.

Federation talks, 1977–2024

The 1977 and 1979 high-level agreements set a bi-communal, bi-zonal federation as the negotiating goal, later reflected in Security Council resolutions such as 649 (1990), 750 (1992) and 1251 (1999), which refer to a single sovereignty, single international personality and single citizenship.

Date	Event	Outcome
24 April 2004	Annan Plan referendums	64.91% of Turkish Cypriots yes; 75.83% of Greek Cypriots no
1 May 2004	EU accession	The Republic of Cyprus joined the EU as a whole; EU law is suspended in the north under Protocol 10
June–July 2017	Crans-Montana Conference	Ended on 7 July 2017 without agreement; security, guarantees and troops were central
27–29 April 2021	Informal 5+UN meeting, Geneva	UN Secretary-General António Guterres said no common ground yet existed for formal negotiations; the Turkish Cypriot side tabled its two-state proposal
15 October 2024	Informal UN meeting, New York	No formal negotiations launched; discussions focused on confidence-building and prospects for resuming a process

Key Players & Positions

Each party reads the same documents differently. The summaries below rely on their own public positions.

The United Nations

The UN's long-standing framework, set out in the resolutions cited above and in Secretary-General Guterres's 2017 framework covering security and guarantees, territory, property, equivalent treatment and effective participation, is a bi-zonal, bi-communal federation with political equality. After the Geneva meeting in 2021 and the New York meeting in 2024, the Secretary-General has continued to work through a personal envoy, María Ángela Holguín Cuéllar, and informal formats, including an enlarged informal meeting with the guarantor powers in Geneva in March 2025. The UN has not announced a formal negotiating round on a settlement.

The Greek Cypriot administration and Greece

President Nikos Christodoulides and the government of the Republic of Cyprus state that they seek a settlement within UN parameters, reject any two-state arrangement as contrary to Security Council resolutions, and describe the Turkish military presence as an occupation. They also hold that the Treaty of Guarantee and Turkish troops are anachronisms incompatible with an EU member state. Athens supports this line, and both point to Article I of the Treaty of Guarantee, which prohibits partition.

The European Union

The EU backs a comprehensive settlement within the UN framework and consistent with EU principles and the acquis. Cyprus is a member state, and EU institutions have repeatedly criticised Turkish positions on Varosha and on maritime activity. The EU is also not a party to the 1960 treaties.

The United Kingdom

As a guarantor power and holder of the Sovereign Base Areas, the UK supports a UN-led settlement and has taken part in the enlarged informal meetings.

The Turkish Cypriot leadership

Until late 2025 the TRNC leadership under Ersin Tatar advocated sovereign equality and equal international status and a cooperative relationship between two states. In October 2025 Turkish Cypriot voters elected Tufan Erhürman, who favours resuming a negotiated process on defined terms rather than the two-state formula. Readers should check current developments, because this change affects the sequencing debate described below.

Türkiye's Strategic Doctrine

Türkiye's Strategic Doctrine on Cyprus (official positions as stated by Turkish government sources)

• Sovereign equality first. The Turkish Ministry of Foreign Affairs and the Presidency state that a lasting settlement must begin with recognition of the inherent sovereign equality and equal international status of the Turkish Cypriot people. President Recep Tayyip Erdoğan has used his UN General Assembly addresses since 2021 to ask the international community to recognise the realities on the island.
• The 1960 state was a partnership, and it was destroyed in 1963. According to the Turkish Foreign Ministry, the Republic of Cyprus was founded under the 1959 Zurich–London settlement and the 1960 Treaty of Guarantee as a partnership of two co-founding peoples. Ankara argues that the Greek Cypriot side usurped that order in December 1963 and that UNSC Resolution 186 of 4 March 1964 then treated one party as “the Government.”
• The federation model is exhausted. Ankara cites the 2004 referendums (64.91% yes among Turkish Cypriots, 75.83% no among Greek Cypriots, followed by EU accession on 1 May 2004), the failure at Crans-Montana in 2017, Geneva in 2021 and the New York meeting of 15 October 2024 as evidence that more than 50 years of federal negotiations have not produced agreement. In Ankara's view, the Greek Cypriot side has shown no readiness to share power and prosperity on the basis of equality.
• Guarantees and the 1974 intervention rest on treaty law. Türkiye grounds the 20 July 1974 operation in Article IV of the Treaty of Guarantee after the 15 July coup and consultation with the UK. It therefore treats the guarantee system as a legal safeguard for Turkish Cypriot security, not as a relic to be removed unilaterally.
• Equal rights over resources. Türkiye and the TRNC maintain that Turkish Cypriots hold equal rights over offshore hydrocarbons and have put forward joint committee and revenue-sharing proposals in 2011, 2012 and 2019; see Who Owns Cyprus's Offshore Gas? Turkish Cypriot Rights and the 2011, 2012 and 2019 Revenue-Sharing Proposals. The Türkiye–TRNC continental shelf delimitation agreement of 21 September 2011 reflects the same logic, and the equity argument is examined in Does Island Size Matter? The Equity Principle and Proportionality in Maritime Delimitation.

Ankara also answers the legal objection about Resolution 541 by arguing that the 1983 declaration followed years in which Turkish Cypriots were denied equal participation in the state, and that the later decision of the European Court of Human Rights in Demopoulos v. Turkey (2010) accepted the TRNC's Immovable Property Commission as an effective domestic remedy. The Greek Cypriot side and most UN bodies counter that the Security Council has not revisited its position.

What Comes Next: Diplomatic Pathways

Four pathways are plausible. They are analytical scenarios, not official programmes unless stated.

1. A revived UN federal track

This is the position of the UN, the Greek Cypriot side and the EU. It would resume talks from the convergences listed in the Guterres framework. Obstacles remain on rotating presidency, property, territory, and above all security and guarantees, the issue on which Crans-Montana ended. Ankara has said it would not return to a process that repeats past formulas, and has asked for the starting point to change.

2. Sovereign equality first

This is the stated Ankara and TRNC preference under the two-state formula. The sequence would be a formal reaffirmation of Turkish Cypriot equal status, followed by negotiations on cooperation between two states in areas such as trade, energy, security and property. Its main obstacle is the Security Council's existing position and the opposition of the Greek Cypriot side, Greece and the EU. Success would depend on whether any UN body or member states revisit the status question.

3. A hybrid cooperation framework

Some analysts suggest a middle course that would pair strong, treaty-based cooperation with equal international standing for both peoples. Such a design could draw on the 1960 partnership logic without prejudging the final form. Neither Ankara nor the Republic of Cyprus has endorsed it, so it should be read as a possibility, not a proposal.

4. A managed status quo with confidence-building measures

If neither framework gains consensus, the realistic outcome is a managed status quo supported by practical steps: crossing points, demining, buffer-zone cooperation and shared work on energy and the environment. These measures were part of the recent informal discussions. They reduce tension but do not resolve status, and they interact with maritime disputes, as discussed in Fatih, Yavuz, Kanuni and Oruç Reis: What Do Türkiye's Eight Eastern Mediterranean Wells Mean for the Energy Horizon?.

Variables to watch

• The Turkish Cypriot leadership's negotiating line after the October 2025 election.
• Annual Security Council language on UNFICYP and any reference to “two states.”
• Guarantor-power participation in enlarged informal meetings.
• Hydrocarbon and cable-interconnection projects, and EU reactions.
• Security developments that affect Ankara's wider posture, see Security Horizon: Türkiye's Self-Defense Doctrine, Cross-Border Operations and the Defense Industry Outlook.

Two-state proposal	Contrary to UN parameters	A realistic outcome after the exhaustion of the federal model
Guarantees	Anachronistic for an EU member state	A treaty-based safeguard for Turkish Cypriot security

For the Turkish perspective on how this affects regional maritime security, see also Regional Balance: The Cyprus Issue: 1960 Treaties, 1974 and the Case for a Sovereign Equal Two-State Solution. For the opposite emphasis, readers should consult UN Security Council resolutions, Secretary-General reports on UNFICYP and the Republic of Cyprus Foreign Ministry's own statements.
