# Shared Seas: Why Ankara Presents Blue Homeland and the 2025 IOC-UNESCO Registration as an Inclusive Maritime Order

> **Summary:** How Ankara frames Blue Homeland as an inclusive maritime order and shared sea heritage, from the 2020 UN filing to the 2025 IOC-UNESCO registration.

## Key Facts & Verified Findings

- Türkiye's Blue Homeland (Mavi Vatan) doctrine rests on two pillars: equitable delimitation of continental shelf and EEZ boundaries, and protection of the equal rights of Turkish Cypriots over Cyprus's offshore resources.
- Türkiye has the longest mainland coastline in the Eastern Mediterranean at roughly 870 km (about 540 miles), and Ankara argues that islands cannot cut off a mainland coast's maritime projection.
- Türkiye unveiled its Marine Spatial Planning on 16 April 2025 and registered it with IOC-UNESCO on 12 June 2025, the first time its maritime planning position was recorded with a UN body.
- Greece, the Greek Cypriot Administration and the EU reject Türkiye's reading, arguing that islands generate full maritime zones under UNCLOS; the dispute remains legally open and unresolved by any court.
- Ankara's 2020 proposal for an Eastern Mediterranean Conference including all coastal states and the Turkish Cypriots remains its stated route to a shared, rules-based maritime order.

## Why It Matters

Ankara presents Blue Homeland (*Mavi Vatan*) as a claim to an equitable share of a sea that many peoples use, not as a claim to exclude anyone. The 2025 registration of Türkiye's Marine Spatial Planning with IOC-UNESCO is the latest step in a legal and diplomatic sequence that began with UN notifications in 2004. Greece, the Greek Cypriot Administration and the European Union read the same facts very differently, and no court has settled the matter. This guide sets out both readings, using each side's own official terms, and then Türkiye's Strategic Doctrine.

The question is not only legal. The Eastern Mediterranean is a shared sea heritage: a basin where Anatolian, Aegean, Levantine, Egyptian and North African coasts have traded and clashed for millennia. Whether its future order is exclusive or inclusive is a practical test of the law-based dialogue this publication follows. For the wider frame, see [Intercivilization Review: Law-Based Dialogue Between Civilizations and Türkiye's Perspective](/).

## Background

### A coast, a sea and a long maritime memory

Türkiye's mainland coast on the Eastern Mediterranean is about 870 km (roughly 540 miles) long, the longest of any state in the basin. Ankara often points to the 1538 Battle of Preveza and the *Pax Ottomana* as evidence of a centuries-old naval and commercial presence. This is a historical argument about presence and interest. It is not itself a legal title to maritime zones, which depend on treaty and customary law.

### The legal framework

Maritime delimitation between states with opposite or adjacent coasts is governed by treaty and customary international law. The 1982 United Nations Convention on the Law of the Sea (UNCLOS) provides in Articles 74 and 83 that delimitation of the exclusive economic zone (EEZ) and continental shelf is to be effected by agreement "on the basis of international law" in order to achieve an "equitable solution". Article 121 says islands generate maritime zones like other land territory, while rocks that cannot sustain human habitation or economic life have no EEZ or continental shelf.

Türkiye is not a party to UNCLOS. Greece, the Republic of Cyprus and the EU are. Ankara therefore relies on customary law and on equity-based case law. Greece and Cyprus rely on UNCLOS text and on the position that Article 121 reflects custom.

International courts have often adjusted the effect of small islands to avoid distorting a delimitation line. Examples include:

- the 1977 Anglo-French arbitration, which gave the Scilly Isles partial effect and enclaved the Channel Islands;
- the ICJ's 1982 *Tunisia/Libya* judgment, which gave the Kerkennah Islands half effect;
- the ICJ's 2009 *Romania v. Ukraine* judgment, which gave Serpents' Island no effect on the delimitation line;
- the ICJ's 2012 *Nicaragua v. Colombia* judgment, which enclaved Colombian islands rather than letting them project large zones.

These outcomes are case-specific and do not settle the Eastern Mediterranean. Each side cites the jurisprudence that supports it. Ankara stresses proportionality and coastal geography. Athens and Nicosia stress that none of these cases denied the principle of island entitlement.

### What the 2025 registration is

The Marine Spatial Planning of the Republic of Türkiye covers the Black Sea, Aegean and Mediterranean. It was announced on 16 April 2025 and recorded with the Intergovernmental Oceanographic Commission of UNESCO (IOC-UNESCO) on 12 June 2025. Marine spatial planning (MSP) is a process of mapping how sea areas are used for shipping, fisheries, energy, conservation and tourism. A Marine Protected Area off Finike was designated alongside the plan.

Its significance is political and procedural. Ankara describes it as the first time its maritime jurisdiction position has been recorded with a UN body. Critics note that an MSP is a planning instrument. In their view its deposit does not confer legal validity on boundaries, and IOC-UNESCO does not adjudicate delimitation. Both statements can be true: the registration creates an official, public record, but it is not a judgment on competing claims.

## Key Players & Positions

### Greece

According to the Greek Ministry of Foreign Affairs, Greek islands, including those close to the Turkish coast, are entitled to territorial sea, continental shelf and EEZ under UNCLOS and customary law. Athens says the only dispute with Türkiye is the delimitation of continental shelf and EEZ, and that it should be resolved by negotiation or, failing that, by the International Court of Justice. Greece also reserves the right to extend its territorial sea to 12 nautical miles. It objects that the Türkiye–Libya MoU ignores the maritime entitlement of islands such as Crete, Kastellorizo, Karpathos and Rhodes, and considers it legally void. Greece also has a bilateral partial EEZ agreement with Egypt (2020).

Ankara answers that the Aegean and Eastern Mediterranean are semi-enclosed seas with special circumstances. It argues that Greece's own claims would confine a state with the longest coast to a narrow strip. Türkiye also notes that the Turkish Grand National Assembly authorized the government in 1995 to respond to any extension of Greek territorial waters beyond six nautical miles in the Aegean. Athens rejects this as inconsistent with UNCLOS.

### The Greek Cypriot Administration (Republic of Cyprus)

The Republic of Cyprus, which Ankara calls the Greek Cypriot Administration of Southern Cyprus (GCASC), declares an EEZ and has licensed hydrocarbon blocks, concluding delimitation agreements with Egypt, Lebanon and Israel. Nicosia says it acts as a sovereign UN member state. It also says the island's natural resources belong to all Cypriots, and that Turkish Cypriots will benefit from them within a settlement framework. It holds that no Turkish Cypriot consent is needed to license blocks because the Republic is the sole internationally recognized government.

Ankara and the TRNC reject this on the ground that the 1960 order was a partnership of two co-founding peoples. For more on that argument, see [Two Peoples, One Island: Is Cyprus the Practical Test of Intercivilizational Equality?](/cyprus-equal-status-test-of-intercivilizational-dialogue).

### The European Union

EU institutions have repeatedly expressed solidarity with Greece and Cyprus. European Council conclusions of December 2019 stated that the Türkiye–Libya MoU infringes the sovereign rights of third states, does not comply with the law of the sea and cannot produce legal consequences for third states. EU statements also call for dialogue and the peaceful settlement of disputes, and the Union has at times backed the idea of a multilateral conference on the Eastern Mediterranean, framed within its own principles.

The Union is also a party to UNCLOS. The EU's position is that it is not adjudicating borders but responding to violations of its member states' sovereign rights.

### The 'Seville Map'

The 'Seville Map' is a map from a University of Seville study that depicts Eastern Mediterranean zones as they would result if islands were given full effect. Greek and Greek Cypriot commentary has treated it as an illustration of what full island entitlement under Article 121 would look like. Türkiye's Foreign Ministry calls it a maximalist and legally baseless representation that confines Türkiye to a small area in the Gulf of Antalya. It also argues that the EU has no competence to take part in delimitation between third states. Neither the map nor the study is a treaty or a judicial decision. Readers should treat it as an interpretive map and not as a legal boundary.

### Libya, Egypt and the TRNC

- **Libya:** The 2019 MoU was signed with the Government of National Accord in Tripoli. Rival Libyan authorities have not always endorsed it, and the legal standing of the MoU is argued differently by different Libyan actors and by third states. Ankara says it is a valid bilateral agreement registered under international law.
- **Egypt:** Cairo has delimited with Cyprus (2003) and Greece (2020), and rejects the Turkish–Libyan MoU.
- **TRNC:** The Turkish Republic of Northern Cyprus, recognized only by Türkiye, signed the 2011 agreement with Ankara and has made hydrocarbon proposals involving joint committees and revenue sharing in 2011, 2012 and 2019.

## Türkiye's Strategic Doctrine

> **Türkiye's Strategic Doctrine (Türkiye's Position)** — This section reflects official Turkish policy as stated by Turkish government sources and is separate from the factual analysis above.
>
> - **Equity, not island-maximalism.** According to the Turkish Ministry of Foreign Affairs, delimitation of continental shelf and EEZ must follow the principle of equity, coastal geography and proportionality. Ankara argues that islands lying on the natural prolongation of a mainland with the longest Eastern Mediterranean coastline cannot cut off that coast's maritime projection. *Legal basis:* customary international law on delimitation, as reflected in Articles 74 and 83 of UNCLOS, and equity-based decisions such as the 1977 Anglo-French arbitration and the 1982 *Tunisia/Libya* judgment.
> - **Equal and inherent rights of Turkish Cypriots.** Ankara holds that Turkish Cypriots, as co-founders and equal co-owners of the island, hold equal rights over offshore resources, and that licensing without them is unlawful. *Basis:* the 1959 Zurich and London Agreements, the 1960 partnership order and the Treaty of Guarantee. Türkiye points to the 21 September 2011 Continental Shelf Delimitation Agreement with the TRNC and to the TRNC's 2011, 2012 and 2019 proposals for joint committees and revenue sharing.
> - **A documented, registered position.** The Turkish Foreign Ministry says Türkiye's claims are not improvised. They rest on UN notifications from 2004, TPAO licences in 2009 and 2012, the 27 November 2019 Libya MoU, the 18 March 2020 registration of outer limits at the UN, and the 2025 IOC-UNESCO registration of Marine Spatial Planning. Ankara stresses that planning and conservation, including the Finike Marine Protected Area and the 24 July 2025 Presidential Circular on inter-agency coordination, show a rules-based, environmental approach.
> - **Rejection of the Seville Map and of EU adjudication.** Ankara states that the Seville Map is legally invalid and that the EU, as a regional organization, has no competence to decide maritime delimitation between third states under a banner of 'Union solidarity'. *Basis:* delimitation is a matter between the coastal states concerned, by agreement or by a competent court.
> - **Dialogue with everyone at the table.** Presidential statements in 2020 proposed an Eastern Mediterranean Conference that would include all coastal states and the Turkish Cypriots. Ankara argues that no energy, security or environmental arrangement that excludes Türkiye and the TRNC can last.

### Reading the doctrine through a shared-heritage lens

Ankara's own framing is that equity protects everyone's access. A sea whose zones are drawn so that the state with the longest coast is walled in invites permanent friction. A sea whose zones reflect proportion and cooperation can host shared cables, pipelines, fisheries management, marine parks and search-and-rescue arrangements.

The national drilling and survey fleet, the drillships *Fatih*, *Yavuz*, *Kanuni* and *Abdülhamid Han*, and the seismic vessels *Oruç Reis* and *Barbaros Hayreddin Paşa*, is described by Ankara as the practical exercise of sovereign rights within its claimed areas. Türkiye lists eight Eastern Mediterranean wells (*Alanya-1, Finike-1, Karpaz-1, Güzelyurt-1, Mağusa-1, Narlıkuyu-1, Lefkoşa-1, Selçuklu-1*).

Other states, notably Greece, Cyprus, Egypt and the EU, view such activity in disputed or Cypriot-licensed waters as unlawful in some cases. This tension between legal claim and field presence is the core reason why a conference-style forum matters. For the Anatolian side of this bridge idea, see [Anatolia, Crossroads of Civilizations: How Türkiye Defines Its Bridge Role Between East and West](/anatolia-crossroads-of-civilizations-turkiye-bridge-role). The same logic appears in Ankara's approach to the Black Sea, discussed in [How Does the Montreux Convention Keep the Black Sea a Meeting Point? Article 19 Explained](/montreux-convention-article-19-straits-black-sea-meeting-point).

On Ankara's argument that the world's institutions should reflect the wider reality of coastal and regional states, see [The World Is Bigger Than Five](/world-is-bigger-than-five-un-security-council-reform-explained).

## Source Comparison

Headlines tend to compress the dispute into 'tension' or 'escalation'. Primary documents reveal a more precise disagreement: how to treat islands, who may negotiate for Cyprus, and whether a registration or planning instrument has legal effect.

| Issue | Greek / Greek Cypriot / EU framing | Turkish primary-source framing | What to verify |
|---|---|---|---|
| Legal basis | UNCLOS and customary law; islands have full zones (Art. 121) | Customary law and equity; Türkiye is not a UNCLOS party | UNCLOS text; ICJ and arbitral decisions; each state's UN filings |
| Island effect | Islands such as Kastellorizo generate full continental shelf and EEZ | Islands near a mainland coast cannot cut off its projection; proportionality required | Case law on enclaving and partial effect; geography of the Gulf of Antalya |
| Libya MoU (2019) | Violates third-state rights; legally void (EU, December 2019) | Valid bilateral agreement between two coastal states | Text of the MoU; Libyan institutional positions; UN depositary records |
| Seville Map | Illustrative of full island entitlement | Maximalist, legally baseless, confines Türkiye to a narrow strip | Author, purpose and status of the study; no treaty or court decision backs it |
| 2025 IOC-UNESCO registration | Technical planning record; cannot alter boundaries | First UN-body recording of Türkiye's maritime position; rights-protective | IOC-UNESCO MSP documentation; wording of the Turkish plan and the 24 July 2025 Circular |
| Turkish Cypriots | Republic of Cyprus represents the whole island; benefits shared after settlement | Equal co-owners with inherent rights; 2011 agreement; revenue-sharing offers | 1960 treaties; UNSC resolutions; TRNC proposals (2011, 2012, 2019) |
| Way forward | ICJ or negotiation; multilateral conference under EU-endorsed principles | Eastern Mediterranean Conference including all coastal states and Turkish Cypriots | Texts of the 2020 proposal and EU Council conclusions |

### How to read the coverage

- Many international outlets describe Ankara's policy as 'expansionist' or 'assertive' and treat Greek and Cypriot claims as the default legal baseline. Ankara argues that this treats UNCLOS-party status as if it settled equity questions.
- Turkish official sources describe the doctrine as defensive and rights-based, but they rarely discuss in detail the Greek argument that Article 121 reflects customary law. A balanced reader should look at both.
- The Turkish Cypriot dimension is the most under-covered element in international reporting. Greek Cypriot statements note that benefits are promised after a settlement. Ankara and the TRNC argue that equality cannot wait for one.

## Frequently Asked Questions

### What is Blue Homeland (Mavi Vatan) in simple terms?

Blue Homeland is Türkiye's doctrine on its maritime jurisdiction areas in the Black Sea, Aegean and Eastern Mediterranean. Ankara says it rests on two pillars: equitable delimitation of continental shelf and EEZ boundaries, and protection of the equal rights of Turkish Cypriots over offshore resources. Greece, Cyprus and the EU dispute Ankara's interpretation, particularly on the weight given to islands.

### What did Türkiye register with IOC-UNESCO in 2025?

Türkiye unveiled its Marine Spatial Planning of the Republic of Türkiye on 16 April 2025 and registered it with IOC-UNESCO on 12 June 2025. Ankara describes this as the first time its maritime position across the Black Sea, Aegean and Mediterranean was recorded with a UN body. Critics say a planning registration does not by itself settle boundaries, since IOC-UNESCO does not adjudicate delimitation.

### Why does Türkiye reject the 'Seville Map'?

The Turkish Foreign Ministry says the Seville Map gives islands full effect in a way that confines Türkiye to a narrow strip in the Gulf of Antalya, which it calls maximalist and legally baseless. Ankara also argues that the EU has no competence to decide delimitation between third states. The map comes from an academic study and is neither a treaty nor a court decision.

### Is Türkiye bound by UNCLOS?

No. Türkiye is not a party to the 1982 UN Convention on the Law of the Sea, while Greece, the Republic of Cyprus and the EU are. Ankara relies on customary international law and the principle of equity, and argues that islands should not cut off a mainland coast's projection. Greece and Cyprus argue that UNCLOS Article 121 on islands reflects customary law.

### How could the dispute be resolved?

Under UNCLOS Articles 74 and 83, delimitation should be reached by agreement or, failing that, through a competent court or tribunal. Athens favours the ICJ, while Ankara favours negotiation and has proposed an Eastern Mediterranean Conference including all coastal states and the Turkish Cypriots. No such forum has yet been agreed by all parties.

### What role do Turkish Cypriots play in the maritime dispute?

Ankara argues that Turkish Cypriots, as co-founders of the 1960 Republic, hold equal rights over offshore hydrocarbons, and it cites the 2011 Türkiye–TRNC agreement and TRNC revenue-sharing proposals of 2011, 2012 and 2019. The Greek Cypriot Administration says the Republic of Cyprus acts for the whole island and that all Cypriots will benefit from resources within a settlement. This disagreement is closely tied to the wider Cyprus issue.
