Question: What type of law defines "states", and their role in an Exclusive Economic Zone?

full_context: Document 1: Extraterritoriality: Extraterritoriality is the state of being exempted from the jurisdiction of local law, usually as the result of diplomatic negotiations. Historically, this applied to individuals. Extraterritoriality can also be applied to physical places, such as foreign embassies, military bases of foreign countries, or offices of the United Nations. The three most common cases recognized today internationally relate to the persons and belongings of foreign heads of state, the persons and belongings of ambassadors and other diplomats, and ships in foreign waters.
Document 2: List of island countries: This is a list of island countries. An island is a land mass (smaller than a continent) that is surrounded by water. Many island countries are spread over an archipelago, as is the case with the Federated States of Micronesia and the Indonesia (which consists of thousands of islands). Others consist of a single island, such as Nauru, or part of an island, such as Haiti. Although Australia is designated as a continent, it is often referred to as an island, as it has no land borders. Some declared island countries are not universally recognized as politically independent, such as Northern Cyprus. Some states, such as Taiwan, officially claim to hold continental territories but are de facto limited to control over islands.
Document 3: Sovereign immunity: Sovereign immunity, or crown immunity, is a legal doctrine by which the sovereign or state cannot commit a legal wrong and is immune from civil suit or criminal prosecution. It is a principle of international law which exempts a sovereign state from the jurisdiction of foreign national courts. Sovereign immunity is based on the concept of sovereignty in the sense that a sovereign may not be subjected without its approval to the jurisdiction of another sovereign. As Lord Atkin observed,
Document 4: List of micronations: Micronations, sometimes also referred to as "model countries" and "new country projects", are small, self-proclaimed entities that claim to be independent sovereign states but which are not acknowledged as such by any recognised sovereign state, or by any supranational organization. They should not be confused with microstates, which are recognised independent states of a small size, nor should they be confused with unrecognised states, which may have legitimate claim to sovereign state status.
Document 5: Territory: A territory is an administrative division, usually an area that is under the jurisdiction of a state. In most countries, a "territory" is an organized division of an area that is controlled by a country but is not formally developed into, or incorporated into, a political unit of the country that is of equal status to other political units that may often be referred to by words such as "provinces" or "states". In international politics, a "territory" is usually a non-sovereign geographic area which has come under the authority of another government; which has not been granted the powers of self-government normally devolved to secondary territorial divisions; or both.
Document 6: Exclusive economic zone of islands: Certain islands have an Exclusive Economic Zone (EEZ) around them, that is, an area within which the state governing the island has special rights to exploit marine resources. In some cases, disputes between nations have arisen regarding the validity of zones that have been declared.
Document 7: Territorial claims in the Arctic: The Arctic consists of land, internal waters, territorial seas, exclusive economic zones (EEZs) and high seas. All land, internal waters, territorial seas and EEZs in the Arctic are under the jurisdiction of one of the five Arctic coastal states: Canada, Norway, Russia, Denmark (via Greenland), and the United States. International law regulates this area as with other portions of the Earth.
Document 8: Exclusive economic zone: An exclusive economic zone (EEZ) is a sea zone prescribed by the United Nations Convention on the Law of the Sea over which a state has special rights regarding the exploration and use of marine resources, including energy production from water and wind. It stretches from the baseline out to 200 nautical miles (nmi) from its coast. In colloquial usage, the term may include the continental shelf. The term does not include either the territorial sea or the continental shelf beyond the 200 nmi limit. The difference between the territorial sea and the exclusive economic zone is that the first confers full sovereignty over the waters, whereas the second is merely a "sovereign right" which refers to the coastal state's rights below the surface of the sea. The surface waters, as can be seen in the map, are international waters.
Document 9: State-owned enterprise: A state-owned enterprise (SOE) is a legal entity that undertakes commercial activities on behalf of the state, its owner. The legal status of SOEs varies from being a part of the government to being stock companies with the state as a regular stockholder. The defining characteristics of SOEs are that they have a distinct legal form and are established to operate in commercial affairs and commercial activities. While they may also have public policy objectives (e.g., a state railway company may aim to make transportation more accessible), SOEs should be differentiated from other forms of government agencies or state entities established to pursue purely nonfinancial objectives.
Document 10: Sovereign state: A sovereign state is, in international law, a nonphysical juridical entity that is represented by one centralized government that has sovereignty over a geographic area. International law defines sovereign states as having a permanent population, defined territory, one government, and the capacity to enter into relations with other sovereign states. It is also normally understood that a sovereign state is neither dependent on nor subjected to any other power or state.
Document 11: Monarch: A monarch is a sovereign head of state in a monarchy. A monarch may exercise the highest authority and power in the state, or others may wield that power on behalf of the monarch. Typically a monarch either personally inherits the lawful right to exercise the state's sovereign rights (often referred to as "the throne" or "the crown") or is selected by an established process from a family or cohort eligible to provide the nation's monarch. Alternatively, an individual may become monarch by conquest, acclamation or a combination of means. A monarch usually reigns for life or until abdication.
Document 12: Isla Aves: Isla de Aves (Spanish for "Island of Birds" or "Birds Island"), or Aves Island, is a Caribbean dependency of Venezuela. It has been the subject of numerous territorial disputes between the neighboring independent islands, such as Dominica, and European mother countries of surrounding dependent islands, such as the Netherlands. It is part of the Aves Ridge and lies to the west of the Windward Islands chain at . It is 375 m in length and never more than 50 m in width, and rises 4 m above the sea on a calm day. Under a particular interpretation of the United Nations Convention on the Law of the Sea it could be classified as a rock, which would only give Venezuela a twelve nautical mile economic zone. However, Venezuela claims it is an island, which grants it a 200 mi exclusive economic zone. Mostly sand, a small portion has some scrubby vegetation. It is sometimes completely submerged during hurricanes. It is 185 km southwest of the closest land, Montserrat, 225 km west of Dominica and 547 km north of the Venezuelan mainland.
Document 13: List of islands in the Persian Gulf: The Persian Gulf is home to many islands, mostly small, distributed in the gulf's entire geographic area and administered by the neighbouring nations. Most islands are sparsely populated, with some being barren, and some utilized for communication, military, or as ship docks. Some of the islands in the Persian Gulf are artificially constructed islands. The artificial islands often serve as tourist resorts, housing developments, or hotels. Despite their small sizes, some of these artificial islands have caused serious hazards for the already fragile ecosystem of the Gulf and its dwindling wildlife mass. A few of the Gulf islands are also historically significant, having been utilized by the ancient empires, neighbouring kingdoms, and in the recent times, colonial powers such as the British empire, and the Portuguese empire. Recent globalization, and discovery of oil, has made some of the Persian Gulf islands very significant for developed nations as a source of oil and raw industrial material. Recent wars, and political unrest has also made these islands strategic military locations for foreign powers from America and Europe.
Document 14: Sovereign immunity in the United States: In United States law, the federal government as well as state and tribal governments generally enjoy sovereign immunity from lawsuits, although in some cases this immunity has been waived by law. Local governments in most jurisdictions enjoy immunity from some forms of suit, particularly in tort. The Foreign Sovereign Immunities Act provides foreign governments, including state-owned companies, with a related form of immunity—state immunity—that shields them from lawsuits except in relation to certain actions relating to commercial activity in the United States. The principle of sovereign immunity in US law was inherited from the English common law legal maxim "rex non potest peccare", meaning "the king can do no wrong."
Document 15: New Zealand outlying islands: The New Zealand outlying islands comprise nine island groups, located in the subtropics and subantarctic, which are part of New Zealand but lie outside of the New Zealand continental shelf. Although considered as integral parts of New Zealand, seven of the nine island groups are not part of any region or district, but are instead designated as "Area Outside Territorial Authority". The two exceptions are the Chatham Islands, which form a special territorial authority (island council) themselves, and the Solander Islands, which are part of the Southland Region and Southland District.
