Exclusive economic zone (EEZ) The exclusive economic zone is a maritime zone established by the United Nations Convention on the Law of the Sea that grants coastal states rights over natural resources and related jurisdiction beyond the territorial sea. The doctrine was codified during the Third United Nations Conference on the Law of the Sea and entered widespread practice following ratification debates in capitals such as Washington, D.C., London, and Tokyo. Its implementation has influenced disputes involving states like China, Brazil, Australia, Japan, and Norway.
Definition and Legal Basis
The EEZ concept is defined in Part V of the United Nations Convention on the Law of the Sea (UNCLOS) and is generally drawn to 200 nautical miles from baselines established under the Convention on the Territorial Sea and the Contiguous Zone. Provisions in UNCLOS interact with precedents from cases adjudicated by the International Court of Justice, the International Tribunal for the Law of the Sea, and arbitral awards such as the South China Sea arbitration (Philippines v. China) and the Norway v. Denmark (Fisheries case). State practice from nations including United States, Russia, India, Canada, and South Africa informs customary international law interpretations applied by tribunals.
Delimitation and Establishment
Delimitation of EEZs often requires bilateral or multilateral agreements negotiated between neighboring states like Spain and Morocco, Argentina and United Kingdom, or Greece and Turkey. When negotiations fail, parties may submit disputes to forums such as the International Court of Justice, the International Tribunal for the Law of the Sea, the Permanent Court of Arbitration, or seek mediation through the United Nations Secretary-General. Technical establishment relies on hydrographic surveys conducted by agencies like the National Oceanic and Atmospheric Administration and the British Hydrographic Office, and submissions to the Commission on the Limits of the Continental Shelf for extended continental shelf claims beyond 200 nautical miles, as seen in filings by Mauritius, Seychelles, and Iceland.
Rights and Jurisdiction of Coastal States
Within the EEZ, coastal states such as Chile, Peru, Senegal, Indonesia, and Philippines exercise sovereign rights for the purpose of exploring and exploiting natural resources, including fisheries, hydrocarbons, and mineral deposits on the seabed. Jurisdictional competences overlap with responsibilities under treaties like the Convention on Biological Diversity and the Convention on International Trade in Endangered Species of Wild Fauna and Flora when regulating living resources and conservation measures. Shipping and navigation rights enjoyed by flag states such as Panama, Liberia, and Marshall Islands remain subject to freedoms recognized in UNCLOS and decisions like those of the International Maritime Organization.
International Disputes and Resolution Mechanisms
High-profile disputes over EEZs have involved cases such as South China Sea arbitration (Philippines v. China), the Iran-Iraq boundary dispute, and maritime boundary adjudications between Peru and Chile, or Bangladesh and Myanmar. Resolution mechanisms include bilateral diplomacy, adjudication by the International Court of Justice, arbitration under the United Nations Convention on the Law of the Sea Annex VII, and joint development agreements exemplified by arrangements between Timor-Leste and Australia or Malaysia and Thailand. Geopolitical actors like NATO members and regional organizations such as the European Union and the African Union have sometimes mediated or influenced outcomes.
Economic Activities and Resource Management
Economic exploitation in EEZs encompasses fisheries managed under regional organizations like the North East Atlantic Fisheries Commission, petroleum exploration licensed by national authorities such as Brazil’s Petrobras and Norway’s Equinor, and seabed mining interests involving companies and states like Nauru and Canada. Management instruments include national legislation mirroring UNCLOS, joint development zones like the Timor Sea Treaty, and regional fisheries management organizations such as the North Pacific Fisheries Commission and the Commission for the Conservation of Antarctic Marine Living Resources. Energy projects intersect with investment regimes overseen by institutions like the World Bank and dispute settlement through the International Centre for Settlement of Investment Disputes.
Environmental Protection and Conservation
Environmental obligations in the EEZ are informed by instruments such as the United Nations Framework Convention on Climate Change, the Convention on Biological Diversity, and the International Convention for the Prevention of Pollution from Ships (MARPOL). Coastal states including New Zealand, Canada, Norway, and Iceland establish marine protected areas and fisheries quotas, often coordinated with regional bodies like the Pacific Islands Forum and scientific guidance from organizations such as the Intergovernmental Oceanographic Commission and the Food and Agriculture Organization. International litigation and advocacy by NGOs such as Greenpeace and World Wide Fund for Nature have pressured states to strengthen conservation within EEZs.
Impact on Maritime Security and Geopolitics
EEZ claims affect naval deployments and security postures of states including the United States Navy, the People's Liberation Army Navy, and the Royal Navy, and have factored into strategic doctrines of alliances like QUAD and partnerships involving Japan and Australia. Resource competition has shaped foreign policy between powers such as China and India and influenced incidents involving coast guards from Vietnam, Philippines, and Malaysia. The intersection of EEZ rights with freedom of navigation operations led by United States and counter-operations by claimants has produced legal, diplomatic, and military tensions addressed in forums like the ASEAN Regional Forum and bilateral security dialogues.
