An Exclusive Economic Zone (EEZ) is the maritime area extending 200 nautical miles from a country's coast in which that country holds sole rights to explore, exploit, and manage natural resources (like fish and offshore oil), as established by the UN Convention on the Law of the Sea (UNCLOS).
An Exclusive Economic Zone is a strip of ocean, stretching up to 200 nautical miles from a country's coastline, where that country gets exclusive rights to the resources. That means the fish, the oil and natural gas under the seabed, even the wind and wave energy. The rules come from the United Nations Convention on the Law of the Sea (UNCLOS), the international agreement that carved the ocean into zones with different levels of state control.
Here's the part that trips people up. An EEZ is about resource rights, not full sovereignty. Inside its EEZ, a state can set fishing quotas, license oil drilling, and kick out foreign trawlers, but it cannot stop foreign ships from sailing through. Compare that to territorial waters (the first 12 nautical miles), where a state has nearly full sovereignty, almost like the water is land. Think of the EEZ as a country's offshore mining claim. You own what's in the ground (and the water), but you can't close the road that runs across it.
EEZs live in Topic 4.5: The Function of Political Boundaries (Unit 4) and directly support learning objective 4.5.A, explaining the nature and function of international boundaries. The CED's essential knowledge spells out why this term matters. EK IMP-4.B.3 says maritime boundaries and international agreements can encourage or discourage interactions and create disputes over resources, and UNCLOS is the textbook example of an international agreement drawing those maritime boundaries. EEZs also connect to EK IMP-4.B.1, since maritime boundaries are defined and administered to set limits of sovereignty but are often contested. When two countries' coastlines sit less than 400 nautical miles apart, their EEZ claims overlap, and that overlap is where real-world conflicts (like competing claims in the South China Sea) come from. If an exam question mentions UNCLOS, fishing rights, or a 200-nautical-mile zone, it's testing this concept.

Contiguous Zone (Unit 4)
UNCLOS creates a ladder of zones with decreasing state control as you move offshore. Territorial waters (12 nm, near-full sovereignty), then the contiguous zone (out to 24 nm, enforcement of customs and immigration laws), then the EEZ (out to 200 nm, resource rights only). Knowing where each rung sits on that ladder is exactly what MCQs test.
Allocational Disputes (Unit 4)
An allocational dispute is a fight over resources that cross or sit near a boundary, and overlapping EEZ claims are the classic maritime version. When two states both claim the same fishing grounds or undersea oil field, you've got an allocational dispute generated by an EEZ boundary.
Berlin Conference (Unit 4)
The CED pairs these for a reason. Both show boundaries created by policy and international agreement rather than by culture or nature. The Berlin Conference drew lines across land in Africa; UNCLOS drew lines across the ocean. Same idea, different surface.
Devolution and State Power (Unit 4)
EEZs flip the usual Unit 4 story. While devolution shows states losing power inward, EEZs show states extending power outward, projecting sovereignty over huge ocean areas. Small island nations can control EEZs many times larger than their land territory, which reshapes their economic and geopolitical weight.
EEZs show up mostly in multiple-choice questions tied to Topic 4.5, usually in three flavors. First, straight definition stems, like identifying which zone gives a country exclusive rights to marine resources up to 200 nautical miles from its coast. Second, motive questions, asking why a coastal nation would want to maximize its EEZ under UNCLOS (answer: to control more fish, oil, gas, and seabed resources). Third, sovereignty scenarios, like a state setting fishing regulations in its EEZ without consulting anyone, which tests whether you know EEZ rights are exclusive to that state. No released FRQ has used the term verbatim, but boundary-function FRQs often ask you to explain how international agreements create resource disputes, and an EEZ overlap example (like competing South China Sea claims) is a strong, specific answer. Always anchor your answer to UNCLOS and the 200-nautical-mile figure.
Territorial waters are the first 12 nautical miles from the coast, where a state has near-total sovereignty, including over who passes through (with limited exceptions). An EEZ stretches much farther, to 200 nautical miles, but grants only resource rights. Foreign ships and planes can travel freely through an EEZ; they just can't fish or drill there. If the question is about sovereignty over the water itself, think territorial waters. If it's about who gets the fish and the oil, think EEZ.
An EEZ extends up to 200 nautical miles from a country's coastline and gives that country exclusive rights to natural resources like fish, oil, and natural gas.
EEZs were established by the United Nations Convention on the Law of the Sea (UNCLOS), the key international agreement defining maritime boundaries.
An EEZ grants resource rights, not full sovereignty, so foreign ships can still navigate freely through it.
EEZs sit beyond territorial waters (12 nm of near-full sovereignty) and the contiguous zone (24 nm of law enforcement rights) on the UNCLOS ladder of decreasing control.
Overlapping EEZ claims between nearby coastal states create allocational disputes over resources, which is exactly the boundary conflict EK IMP-4.B.3 describes.
On the exam, the trigger words are UNCLOS, 200 nautical miles, and fishing or drilling rights, and they all point to the EEZ.
It's the ocean zone extending 200 nautical miles from a country's coast where that country has exclusive rights to natural resources like fish and offshore oil. It was created by UNCLOS, the UN Convention on the Law of the Sea, and shows up in Topic 4.5 on boundary functions.
No. A country has sovereign rights to the resources in its EEZ (fishing, drilling, energy), but not full sovereignty over the water. Foreign ships can sail through an EEZ freely, unlike territorial waters where the coastal state controls passage.
Territorial waters cover the first 12 nautical miles from shore with near-complete sovereignty, while the EEZ runs out to 200 nautical miles with resource rights only. Distance and degree of control are the two things MCQs test.
Up to 200 nautical miles from the coastline. When two countries' coasts are closer than 400 nautical miles apart, their EEZ claims overlap and have to be negotiated, which is a major source of maritime resource disputes.
Because EEZs control valuable resources like fisheries, oil, and natural gas, and overlapping claims create allocational disputes. The South China Sea, where multiple states claim overlapping zones, is the go-to example for an FRQ on boundary-driven resource conflict.
