"영해" refers to the territorial sea of a coastal state, extending up to 12 nautical miles from its baseline. This area is under the jurisdiction of the state, meaning it can enforce laws, regulate resources, and control navigation. The concept of 영해 is important for maintaining national sovereignty over marine resources and ensuring maritime security. In international law, the rights and responsibilities of states regarding 영해 are outlined in the United Nations Convention on the Law of the Sea (UNCLOS). This framework helps resolve disputes and promotes cooperation among nations in managing ocean resources and protecting the marine environment.
