Exclusive Economic Zone - Definition

Definition

Generally, a state's EEZ extends to a distance of 200 nautical miles (370 km) out from its coastal baseline. The exception to this rule occurs when EEZs would overlap; that is, state coastal baselines are less than 400 nautical miles (740 km) apart. When an overlap occurs, it is up to the states to delineate the actual maritime boundary. Generally, any point within an overlapping area defaults to the nearest state.

A state's exclusive economic zone starts at the seaward edge of its territorial sea and extends outward to a distance of 200 nautical miles (370.4 km) from the baseline. The exclusive economic zone stretches much further into sea than the territorial waters, which end at 12 NM (22 km) from the coastal baseline (if following the rules set out in the UN Convention on the Law of the Sea). Thus, the EEZ includes the contiguous zone. States also have rights to the seabed of what is called the continental shelf up to 350 nautical miles (648 km) from the coastal baseline, beyond the EEZ, but such areas are not part of their EEZ. The legal definition of the continental shelf does not directly correspond to the geological meaning of the term, as it also includes the continental rise and slope, and the entire seabed within the EEZ.
