caption_attribution_description: English: Territorial map claimed by the Philippines, showing internal waters, territorial sea, international treaty limits and exclusive economic zone.
context_page_description: The term territorial waters is sometimes used informally to refer to any area of water over which a state has jurisdiction, including internal waters, the territorial sea, the contiguous zone, the exclusive economic zone and potentially the continental shelf. In a narrower sense, the term is used as a synonym for the territorial sea.
context_section_description: Waters landward of the baseline are defined as internal waters, over which the state has complete sovereignty: not even innocent passage is allowed without explicit permission from said state. Lakes and rivers are considered internal waters. All "archipelagic waters" within the outermost islands of an archipelagic state such as Indonesia or the Philippines are also considered internal waters, and are treated the same with the exception that innocent passage through them must be allowed. However, archipelagic states may designate certain sea lanes through these waters.
