The United Nations Convention on the Law of the Sea (UNCLOS), also called the Law of the Sea Convention or the Law of the Sea Treaty, is an international agreement that establishes a legal framework for all marine and maritime activities. As of June 2016 [update] , 167 countries and the European Union are parties.
The Convention resulted from the third United Nations Conference on the Law of the Sea (UNCLOS III), which took place between 1973 and 1982. UNCLOS replaced the four treaties of the 1958 Convention on the High Seas. UNCLOS came into force in 1994, a year after Guyana became the 60th nation to ratify the treaty.It is uncertain as to what extent the Convention codifies customary international law.
While the Secretary-General of the United Nations receives instruments of ratification and accession and the UN provides support for meetings of states party to the Convention, the United Nations Secretariat has no direct operational role in the implementation of the Convention. A UN specialized agency, the International Maritime Organization, does play a role, however, as well as other bodies such as the International Whaling Commission and the International Seabed Authority (ISA), which was established by the Convention itself.
UNCLOS replaces the older 'freedom of the seas' concept, dating from the 17th century. According to this concept, national rights were limited to a specified belt of water extending from a nation's coastlines, usually 3 nautical miles (5.6 km; 3.5 mi) (three-mile limit), according to the 'cannon shot' rule developed by the Dutch jurist Cornelius van Bynkershoek. All waters beyond national boundaries were considered international waters: free to all nations, but belonging to none of them (the mare liberum principle promulgated by Hugo Grotius).
In the early 20th century, some nations expressed their desire to extend national claims: to include mineral resources, to protect fish stocks, and to provide the means to enforce pollution controls. (The League of Nations called a 1930 conference at The Hague, but no agreements resulted. 200 nautical miles (370 km; 230 mi) to cover their Humboldt Current fishing grounds. Other nations extended their territorial seas to 12 nautical miles (22 km; 14 mi).) Using the customary international law principle of a nation's right to protect its natural resources, President Harry S. Truman in 1945 extended United States control to all the natural resources of its continental shelf. Other nations were quick to follow suit. Between 1946 and 1950, Chile, Peru, and Ecuador extended their rights to a distance of
By 1967, only 25 nations still used the old three nautical mile limit, 12-nautical-mile (22 km) territorial limit and eight had set a 200-nautical-mile (370 km) limit. As of 28 May 2008 [update] , only two countries still use the 3-mile (4.8 km) limit: Jordan and Palau. That limit is also used in certain Australian islands, an area of Belize, some Japanese straits, certain areas of Papua New Guinea, and a few British Overseas Territories, such as Gibraltar.while 66 nations had set a
UNCLOS does not deal with matters of territorial disputes or to resolve issues of sovereignty, as that field is governed by rules of customary international law on the acquisition and loss of territory.

In 1956, the United Nations held its first Conference on the Law of the Sea (UNCLOS I) at Geneva, Switzerland. UNCLOS Iresulted in four treaties concluded in 1958:
Although UNCLOS I was considered a success, it left open the important issue of breadth of territorial waters.
In 1960, the United Nations held the second Conference on the Law of the Sea ("UNCLOS II"); however, the six-week Geneva conference did not result in any new agreements.Generally speaking, developing nations and third world countries participated only as clients, allies, or dependents of the United States or the Soviet Union, with no significant voice of their own.
The issue of varying claims of territorial waters was raised in the UN in 1967 by Arvid Pardo of Malta, and in 1973 the Third United Nations Conference on the Law of the Sea convened in New York. In an attempt to reduce the possibility of groups of nation-states dominating the negotiations, the conference used a consensus process rather than majority vote. With more than 160 nations participating, the conference lasted until 1982. The resulting convention came into force on 16 November 1994, one year after the 60th state, Guyana, ratified the treaty.
The convention introduced a number of provisions. The most significant issues covered were setting limits, navigation, archipelagic status and transit regimes, exclusive economic zones (EEZs), continental shelf jurisdiction, deep seabed mining, the exploitation regime, protection of the marine environment, scientific research, and settlement of disputes.
The convention set the limit of various areas, measured from a carefully defined baseline. (Normally, a sea baseline follows the low-water line, but when the coastline is deeply indented, has fringing islands or is highly unstable, straight baselines may be used.) The areas are as follows:
The area outside these areas is referred to as the "high seas" or simply "the Area".
Aside from its provisions defining ocean boundaries, the convention establishes general obligations for safeguarding the marine environment and protecting freedom of scientific research on the high seas, and also creates an innovative legal regime for controlling mineral resource exploitation in deep seabed areas beyond national jurisdiction, through an International Seabed Authority and the common heritage of mankind principle.
Landlocked states are given a right of access to and from the sea, without taxation of traffic through transit states.
Part XI of the Convention provides for a regime relating to minerals on the seabed outside any state's territorial waters or EEZ (Exclusive Economic Zones). It establishes an International Seabed Authority (ISA) to authorize seabed exploration and mining and collect and distribute the seabed mining royalty.
The United States objected to the provisions of Part XI of the Convention on several grounds, arguing that the treaty was unfavorable to American economic and security interests. Due to Part XI, the United States refused to ratify the UNCLOS, although it expressed agreement with the remaining provisions of the Convention.
From 1982 to 1990, the United States accepted all but Part XI as customary international law, while attempting to establish an alternative regime for exploitation of the minerals of the deep seabed. An agreement was made with other seabed mining nations and licenses were granted to four international consortia. Concurrently, the Preparatory Commission was established to prepare for the eventual coming into force of the Convention-recognized claims by applicants, sponsored by signatories of the Convention. Overlaps between the two groups were resolved, but a decline in the demand for minerals from the seabed made the seabed regime significantly less relevant. In addition, the decline of Communism in the late 1980s removed much of the support for some of the more contentious Part XI provisions.[ citation needed ]
In 1990, consultations began between signatories and non-signatories (including the United States) over the possibility of modifying the Convention to allow the industrialized countries to join the Convention. The resulting 1994 Agreement on Implementation was adopted as a binding international Convention. It mandated that key articles, including those on limitation of seabed production and mandatory technology transfer, would not be applied, that the United States, if it became a member, would be guaranteed a seat on the Council of the International Seabed Authority, and finally, that voting would be done in groups, with each group able to block decisions on substantive matters. The 1994 Agreement also established a Finance Committee that would originate the financial decisions of the Authority, to which the largest donors would automatically be members and in which decisions would be made by consensus.
On 1 February 2011, the Seabed Disputes Chamber of the International Tribunal for the Law of the Sea (ITLOS) issued an advisory opinion concerning the legal responsibilities and obligations of States Parties to the Convention with respect to the sponsorship of activities in the Area in accordance with Part XI of the Convention and the 1994 Agreement.The advisory opinion was issued in response to a formal request made by the International Seabed Authority following two prior applications the Authority's Legal and Technical Commission had received from the Republic of Nauru and the Kingdom of Tonga regarding proposed activities (a plan of work to explore for polymetallic nodules) to be undertaken in the Area by two State-sponsored contractors – Nauru Ocean Resources Inc. (sponsored by the Republic of Nauru) and Tonga Offshore Mining Ltd. (sponsored by the Kingdom of Tonga). The advisory opinion set forth the international legal responsibilities and obligations of Sponsoring States and the Authority to ensure that sponsored activities do not harm the marine environment, consistent with the applicable provisions of UNCLOS Part XI, Authority regulations, ITLOS case law, other international environmental treaties, and Principle 15 of the UN Rio Declaration.
Part XII of UNCLOS contains special provisions for the protection of the marine environment, obligating all States to collaborate in this matter, as well as placing special obligations on flag States to ensure that ships under their flags adhere to international environmental regulations, often adopted by the IMO. The MARPOL Convention is an example of such regulation. Part XII also bestows coastal and port states with broadened jurisdictional rights for enforcing international environmental regulation within their territory and on the high seas.The United Nations Sustainable Development Goal 14 additionally has a target regarding conservative and sustainable use of oceans and their resources in line with UNCLOS legal framework.
In 2017, the United Nations General Assembly (UNGA) voted to convene an intergovernmental conference (IGC) to consider establishing an international legally-binding instrument (ILBI) on the conservation and sustainable use of biodiversity beyond national jurisdiction (BBNJ). The IGC will convene for a series of four sessions between 2018 and 2020 to work towards an agreement.
The convention was opened for signature on 10 December 1982 and entered into force on 16 November 1994 upon deposition of the 60th instrument of ratification.The convention has been ratified by 168 parties, which includes 164 UN member states, 1 UN Observer state (Palestine) and two associated countries (the Cook Islands and Niue) plus the European Union.
The significance of UNCLOS stems from the fact that it systemizes and codifies the standards and principles of international maritime law, which are based on centuries of maritime experience and are expressed to a great extent in the United Nations Charter and current international maritime law norms, such as the Geneva Conventions of 1958. A large portion of these requirements were further strengthened and expanded.

The East China Sea is an arm of the Western Pacific Ocean, located directly offshore from East China, covering an area of roughly 1,249,000 square kilometers (482,000 sq mi). Its northern extension between mainland China and the Korean Peninsula is the Yellow Sea, separated by an imaginary line between the eastern tip of Qidong at the Yangtze River estuary and the southwestern tip of South Korea's Jeju Island.
The terms international waters or trans-boundary waters apply where any of the following types of bodies of water transcend international boundaries: oceans, large marine ecosystems, enclosed or semi-enclosed regional seas and estuaries, rivers, lakes, groundwater systems (aquifers), and wetlands.
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.
Law of the sea is a body of international law governing the rights and duties of states in maritime environments. It concerns matters such as navigational rights, sea mineral claims, and coastal waters jurisdiction.
An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign 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 the coast of the state in question. It is also referred to as a maritime continental margin and, in colloquial usage, may include the continental shelf. The term does not include either the territorial sea or the continental shelf beyond the 200 nautical mile 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.
According to the United Nations Convention on the Law of the Sea, a nation's internal waters include waters on the side of the baseline of a nation's territorial waters that is facing toward the land, except in archipelagic states. It includes waterways such as rivers and canals, and sometimes the water within small bays.
The Arctic consists of land, internal waters, territorial seas, exclusive economic zones (EEZs) and international waters above the Arctic Circle. All land, internal waters, territorial seas and EEZs in the Arctic are under the jurisdiction of one of the eight Arctic coastal states: Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden and the United States. International law regulates this area as with other portions of Earth.
The Outer Continental Shelf (OCS) is a feature of the geography of the United States. The OCS is the part of the internationally recognized continental shelf of the United States which does not fall under the jurisdictions of the individual U.S. states.
The Australia–Indonesia border is a maritime boundary running west from the two countries' tripoint maritime boundary with Papua New Guinea in the western entrance to the Torres Straits, through the Arafura Sea and Timor Sea, and terminating in the Indian Ocean. The boundary is, however, broken by the Timor Gap, where Australian and East Timorese territorial waters meet and where the two countries have overlapping claims to the seabed.
The Convention on the Continental Shelf was an international treaty created to codify the rules of international law relating to continental shelves. The treaty, after entering into force 10 June 1964, established the rights of a sovereign state over the continental shelf surrounding it, if there be any. The treaty was one of three agreed upon at the first United Nations Convention on the Law of the Sea. It has since been superseded by a new agreement reached in 1982 at UNCLOS III.
The United States was among the nations that participated in the third United Nations Conference on the Law of the Sea, which took place from 1974 through 1982 and resulted in the international treaty known as the United Nations Convention on the Law of the Sea (UNCLOS). The United States also participated in the subsequent negotiations of modifications to the treaty from 1990 to 1994. The UNCLOS came into force in 1994. Although the United States now recognizes the UNCLOS as a codification of customary international law, it has not ratified it.
A maritime boundary is a conceptual division of the Earth's water surface areas using physiographic or geopolitical criteria. As such, it usually bounds areas of exclusive national rights over mineral and biological resources, encompassing maritime features, limits and zones. Generally, a maritime boundary is delineated at a particular distance from a jurisdiction's coastline. Although in some countries the term maritime boundary represents borders of a maritime nation that are recognized by the United Nations Convention on the Law of the Sea, maritime borders usually serve to identify the edge of international waters.
The Republic of Cyprus (Cyprus) and Turkey have been engaged in a dispute over the extent of their exclusive economic zones (EEZ), ostensibly sparked by oil and gas exploration in the area. Turkey objects to Cypriot drilling in waters that Cyprus has asserted a claim to under international maritime law. The present maritime zones dispute touches on the perennial Cyprus and Aegean disputes; Turkey is the only member state of the United Nations that does not recognise Cyprus, and is one of the few not signatory to the United Nations Convention on the Law of the Sea, which Cyprus has signed and ratified.
There are disputes between China, Japan, and South Korea over the extent of their respective exclusive economic zones (EEZs) in the East China Sea.
Several states have claimed interests over the sea bed adjoining Rockall, an uninhabitable granite islet which is located within the exclusive economic zone (EEZ) of the United Kingdom. Ireland, Denmark, Iceland, and the United Kingdom have all made submissions to the commission set up under the United Nations Convention on the Law of the Sea (UNCLOS).
The exclusive economic zone of Somalia covers 830,389 km2 in the Indian Ocean. It extends to a distance of 200 nautical miles from the baselines, from which the breadth of the nation's territorial waters is measured. In accordance with Law No. 37 passed in 1972, Somalia's EEZ falls under its territorial sovereignty.
Japan has the eighth-largest exclusive economic zone (EEZ) in the world. The total area of Japan is about 377,975.24 km2. Japan's EEZ area is vast and the territorial waters and EEZ together is about 4.48 million km2.
Australia's exclusive economic zone (EEZ) was declared on 1 August 1994 and extends from 12 to 200 nautical miles from the coastline of Australia and its external territories, except where a maritime delimitation agreement exists with another state. To the 12 nautical-mile boundary is Australia's territorial waters. Australia has the third-largest exclusive economic zone, behind the United States and France but ahead of Russia, with the total area of 8,148,250 square kilometres (3,146,060 sq mi), which exceeds its land territory.
The borders of Indonesia include land and maritime borders with Malaysia, Papua New Guinea, and Timor Leste, as well as shared maritime boundaries with Australia, India, Palau, Philippines, Singapore, Thailand, and Vietnam.
The exclusive economic zone of Canada is the area of the sea in which Canada has special rights regarding the exploration and use of marine resources, as prescribed by the 1982 United Nations Convention on the Law of the Sea.
