An Exclusive Economic Zone does not grant absolute territorial sovereignty to a coastal state. However, it secures the exclusive rights of a coastal state to explore and exploit vital economic resources within the water column and the seabed. In an era of intense geopolitical competition, Türkiye introduced the Blue Homeland doctrine as a comprehensive maritime strategy. This visionary strategic framework protects these rights and safeguards Ankara’s long-term interests in its surrounding seas. The implementation of this doctrine represents a fundamental shift in regional maritime geopolitics. 

The Aegean Sea and the Territorial Waters Status Quo 

Greece has long-standing ambitions to extend its territorial waters to 12 nautical miles in the Aegean Sea. This proposed move would severely threaten regional stability and the delicate balance established over decades. Historically, Türkiye has declared that such an extension is an indisputable cause of war. 

Currently, Türkiye is not a signatory to the 1982 United Nations Convention on the Law of the Sea. This abstention stems from the unique geographical structure of the Aegean Sea. Historically referred to as the Sea of Islands, the Aegean defies standard nautical mile limitations designed for open oceans. Applying these standard rules would severely restrict international airspace and maritime navigation. 

While Athens maintains a six-mile limit for now, it has militarized numerous Aegean islands despite Turkish claims that such deployments violate the demilitarization provisions of the Lausanne and Paris treaties. These historical agreements explicitly conditioned Greek sovereignty over these islands on their strict demilitarization. Consequently, the current militarization efforts undermine the foundational legal texts governing the region. 

Fault Lines in the Eastern Mediterranean 

In the Eastern Mediterranean, shifting geopolitical fault lines have given Türkiye a significant strategic advantage. In 2019, Ankara signed a Maritime Delimitation Memorandum of Understanding with Libya. This pivotal agreement completely dismantled the maritime containment strategy devised by Greece, Egypt, and the Greek Cypriot Administration. 

Simultaneously, lucrative natural gas discoveries have transformed the Eastern Mediterranean into a focal point of global energy competition. Initial efforts by opposing blocs attempted to exclude Türkiye from regional energy infrastructure, notably through the unviable EastMed pipeline project. However, the subsequent failure of these exclusionary projects proved that no regional energy equation can succeed without Türkiye’s participation. 

Today, Türkiye systematically codifies its maritime jurisdiction zones to consolidate these strategic gains. By defining legal boundaries for disputes dating back to 1982, Ankara actively redraws the Eastern Mediterranean energy map. Domestically, the Blue Homeland doctrine enjoys a robust bipartisan consensus across the political spectrum. The Turkish parliament is expected to legalize these maritime boundaries soon. Moving forward, Greece must face this newly established strategic reality. Athens must factor in both the regional energy resources and the renewed Libyan geopolitical equation. Rejecting diplomatic negotiations in favor of maximalist policies will not yield favorable outcomes for Athens. 

The Legalization of the Blue Homeland 

Declaring an exclusive economic zone establishes a definitive and recognized legal framework. It places all living and non-living resources within the water column and the seabed under the strict jurisdiction of a single state. The upcoming legislative steps of Türkiye will reinforce its sovereignty in the Aegean Sea. This definitive legal action preempts Greek claims to these contested waters. 

Crucially, this legal framework encompasses one hundred and seventy-six islands, islets, and rocks whose sovereignty remains disputed. Historical treaties never explicitly ceded the sovereignty of these specific geographic formations to Greece. Thus, this upcoming legislation solidifies both the legal and practical reality of the Blue Homeland doctrine. 

Under the current Territorial Waters Law of Türkiye, the Aegean boundary remains at six nautical miles strictly out of geographical necessity. In contrast, Türkiye applies the standard 12-mile limit smoothly in the Mediterranean and Black Seas. Despite this delicate equilibrium, Greece recently announced plans to create large national marine parks slated for 2025. This environmental initiative reveals a clear intent to establish unilateral control over disputed waters. Consequently, it poses a direct and unacceptable challenge to Türkiye’s maritime rights. 

Growing Concern in Athens 

Unsurprisingly, these structural moves trigger profound anxiety within political circles in Athens. The Greek government publicly expresses fears that codifying Türkiye’s maritime claims could be an immediate cause of war, as the Turkish parliament declared in 1995. Meanwhile, the Greek domestic press frequently accuses its administration of underestimating these significant developments. 

Greek media openly acknowledges that Türkiye’s growing geopolitical influence fundamentally shifts the regional balance of power. Greek outlets often mischaracterize this growing influence as Turkish revisionism. This rhetoric serves to mask that Ankara seeks to secure its rights under international law. 

Toward a New Regional Security Architecture 

The international system of today faces profound crises of global hegemony and a turbulent transition of power. Leaving maritime boundaries ambiguous in the Aegean and Eastern Mediterranean creates a massive and dangerous security vacuum. The recent initiative of Türkiye anchors its Blue Homeland vision upon a solid, unshakeable legal foundation. 

This codification is a proactive measure carefully designed to close the existing security gap. The international community and regional actors should not view Ankara’s actions as aggressive revisionism. Instead, they represent the foundational building blocks of a new regional security architecture. This new system is firmly grounded in legal clarity, effective deterrence, and geopolitical realism.

Redrawn Boundaries in the Eastern Mediterranean: Türkiye’s New Legal Moves was originally published on Global Security Review.

The Strait of Hormuz crisis and the continuing crisis in the Bab al-Mandab Strait have shown that narrow maritime passages can and will be used as political weapons in future conflicts. The state actors in Tehran and the non-state actors in Sanaa, however, may not be the only ones that may leverage these choke points in future. For example, Oman’s ports could present an essential part of any land route alternatives like the India-Middle East-Europe Economic Corridor (IMEC) that avoid both the Gulf of Aden and the Strait of Hormuz. However, they have also faced drone attacks in the current war and will likely face political instabilities in future. An alternative that has come into greater focus is the North Sea Route (NSR) or the Arctic route. Surprisingly, recent reductions in Arctic ice levels have increased the feasibility of using the NSR, now potentially facilitating the movement of goods. 

Iran asserts its right to regulate shipping in the Strait of Hormuz. Under its 1993 law, innocent passage is subject to prior authorization based on Iran’s national security. The present crisis created by the Iran war has highlighted how the food security of many countries is connected to oil through fertilizer prices, which have witnessed a price surge. Before the war, around 30% of global fertilizers were exported by gulf countries through the Strait of Hormuz. Additionally, 20% of global liquified natural gas is used as the feedstock for making fertilizers and much traveled through the Suez Canal before the Houthis disrupted trade. While the rest of the world will face higher food prices, the Gulf countries, which import up to 85% of their food, are still affected. Asian countries like China, India, Philippines, Thailand, Vietnam, and Singapore are highly dependent on oil imports from the Middle East and must now find alternatives. In the present crisis, increased imports from the U.S. have provided relief to these countries, but the Cape of Good Hope route, needed for this transport, is time-consuming and increases costs.  

The NSR is also not without its share of complex legal matters. Russia has established laws and codes for regulating passage through NSR. Russia classifies the NSR as its internal waters and does not recognize the international right of innocent passage through it. All ships need prior authorization while foreign warships must notify their intended passage 90 days in advance. Ships may be required to use the services of Russian icebreaker escorts and pilots. Russia justifies its claim under article 234 of the United Nations Convention on the Law of the Sea (UNCLOS). Known as the “Arctic Exception,” it applies to all “Ice-covered areas.” It grants coastal states the right to enforce non-discriminatory laws in their Exclusive Economic Zones (EEZ) to prevent marine pollution in the ice-covered areas. The U.S. and other countries argue that UNCLOS protects innocent passage through territorial seas and hence the Russian law is contrary to the provisions of UNCLOS. 

Unlike the Middle East shipping passages, however, the NSR has been in conflict and has not had any kinetic combat or active armed conflict. The free navigation operations may operate here because the U.S. may be reluctant to indulge in hostilities against and may not be equipped to do so. Simultaneously, there may be U.S. interest in selling its oil to East, Southeast, and South Asia through this route. Russia may also find advantage in developing this route and is seeking partners to develop it. Several countries have already reached agreements with Russia to take advantage of the NSR. 

Russia is already using its Arctic coast seasonally to deliver LNG from its Yamal project to Europe and Asia. With increasing arctic warming and higher investment in icebreakers, this may change to round-the-year operations. The present bonhomie between Putin and Xi Jinping had already led to the October 2025 Harbin agreement to make NSR a strategic Arctic trade corridor. NSR suits China for another reason. It reduces heavy Chinese dependence on transit through the Malacca Strait, where India is developing an island base with potential to choke that passage. 

India is diplomatically very heavily invested in the Middle East and has been seeking a route to Europe through Iran and through IMEC. If India were to shift to oil and gas imports through NSR it could face strong pushback and heavy geopolitical pressure. The shift will come with another risk; the conflict zone in the Middle East will be swapped for the possible U.S.-Russian tensions in the narrow Bering Strait and make India dependent on a Sino-Russian architecture beyond its control. Even so, that scenario may still be a long way off. A positive aspect is India’s long-standing trade and military engagement with Russia that has proved its strength in crises. In December 2025, Russia and India signed an agreement formalizing Indian military access to Russia’s Arctic naval ports. Long-term contracts for oil and gas and equity participation in the Arctic infrastructure and shipping capacity may follow. 

For India and Southeast Asian countries, the year-round availability of the NSR will increase overall energy resilience by creating an alternative route that will dampen price surges during the frequent Middle East crises. It will make it more feasible for these countries to tap into multiple oil and gas sources including Russia and the U.S. and, in addition, provide a faster sea route to Europe. There is also the feasibility of synergy between the energy needs of India, the ship-building capacity of South Korea, and the NSR. While the Arctic route will not be a silver bullet for Asian countries to have risk-free access to oil and gas, the shift of focus from the tropics to the North Pole shall reduce the historic leverage by the Middle East and will help keep prices and access stable even during the recurring Middle East flare-ups.
