Areas of the sea not subject to the jurisdiction of any single state are termed the high seas. These areas, often referred to by another name, begin beyond the exclusive economic zone (EEZ) of coastal nations, typically 200 nautical miles from shore. Vessels from any nation can navigate these waters, conduct fishing, and perform research, subject to certain international agreements.
These areas are crucial for global trade, resource management, and freedom of navigation. Historically, the concept has evolved to balance the rights of individual nations with the need for shared access and resource utilization. International agreements govern activities in these areas to prevent conflict, protect marine environments, and ensure sustainable use of resources.
