Exclusive Economic Zones
The 200-nautical-mile zone where states control resources but not navigation.
The EEZ Regime
The Exclusive Economic Zone (EEZ) extends up to 200 nautical miles from the baseline. It is neither territorial sea nor high seas — it is a sui generis zone with a specific bundle of rights. The coastal state has sovereign rights over all natural resources (fish, oil, gas, minerals) and jurisdiction over artificial islands, marine scientific research, and environmental protection.
Crucially, other states retain freedoms of navigation, overflight, and laying submarine cables and pipelines. This distinction is the source of major disputes: China argues that military activities (surveillance flights, naval exercises) in its EEZ require consent, while the US insists these are protected freedoms. This disagreement has caused numerous confrontations in the South China Sea.
