The Contiguous Zone is a maritime area that extends up to 24 nautical miles from a country's baseline. In this zone, a state can enforce laws related to customs, immigration, and sanitation, although it does not have full sovereignty like in its territorial waters. This zone serves as a buffer, allowing countries to monitor and control activities that may affect their security and resources. It is important for maintaining order at sea and protecting a nation's interests, especially in relation to fishing and shipping activities in the surrounding waters.
