It stretches from the outer limit of the territorial sea (22.224 kilometres or 12nautical miles from the baseline) out 370.4 kilometres (or 200 nautical miles) from the coast of the state in question. It is also referred to as amaritime continental margin and, in colloquial usage, may include thecontinental shelf. The term does not include either theterritorial 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 fullsovereignty 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 areinternational waters.[2]
Generally, a state's exclusive economic zone is an area beyond and adjacent to the territorial sea, extending seaward to a distance of no more than 200 nmi (370 km) out from its coastalbaseline.[3] The exception to this rule occurs when exclusive economic zones would overlap; that is, state coastal baselines are less than 400 nmi (741 km) apart. When an overlap occurs, it is up to the states to delineate the actualmaritime boundary.[4] Generally, any point within an overlapping area defaults to the nearest state.[5]
States also have rights to theseabed of what is called theextended continental shelf up to 350 nmi (648 km) from the coastal baseline, beyond the exclusive economic zones, but such areas are not part of their exclusive economic zones.
The legal definition of the continental shelf does not correspond exactly to the geological meaning of the term, as it also includes the continental rise and slope, and the entire seabed within the exclusive economic zone.
The idea of allotting nations' EEZs to give them more control of maritime affairs outside territorial limits gained acceptance in the late 20th century.
Initially, a country's sovereign territorial waters extended 3 nmi (6 km) (range of cannon shot) beyond the shore.[citation needed] In modern times, a country's sovereign territorial waters extend to 12 nmi (22 km) beyond the shore.[citation needed] One of the first assertions of exclusive jurisdiction beyond the traditional territorial seas was made by the United States in theTruman Proclamation of 28 September 1945. However, it wasChile and Peru respectively that first claimed maritime zones of 200 nautical miles with the Presidential Declaration Concerning Continental Shelf signed by Chilean PresidentGabriel Gonzalez Videla on 23 June 1947[6] and by Peruvian PresidentJose Luis Bustamante y Rivero through Presidential Decree No. 781 of 1 August 1947[7][8]
Several countries (Denmark, Iceland, Ireland, and the United Kingdom) havecompeting claims to the continental shelf nearRockall, an uninhabitable rock located in the EEZ of the United Kingdom. In addition, sinceBrexit the United Kingdom has claimed a 12 nautical miles (22 km) exclusion zone around Rockall, which Ireland does not recognise.[9][10][11]
In 1996, theDominican Republic andUnited Kingdom signed an agreement establishing a simplifiedequidistance boundary between theBritish Overseas Territory ofTurks and Caicos and the Dominican Republic.Mouchoir Bank fell on the Turks and Caicos side of the boundary, andSilver andNavidad Banks on the Dominican Republic side. However, the agreement was not subsequentlyratified by either party. Instead, theDominican Republic declared itself anarchipelagic state in 2007, claiming sovereignty over Mouchoir Bank and extending its EEZ beyond the boundary agreement with the United Kingdom. The United Kingdom does not accept the archipelagic status and maritime boundaries claimed by the Dominican Republic.[12]
Mauritius claims an EEZ forTromelin Island from France and an EEZ in respect of theBritish Indian Ocean Territory from the UK. An Exclusive Economic Zone covering 2.3 million square kilometres is claimed by Mauritius.
Turkey claims a portion ofCyprus's claimed EEZ based on Turkey's definition that no islands, including Cyprus, can have a full EEZ[17][18] and should only be entitled to 12 nautical miles. Furthermore, theTurkish Republic of Northern Cyprus (TRNC), only recognized by Turkey, also claims portions of Cyprus's claimed EEZ. Turkey also disputesGreece's EEZ for the same reason in regards to its islands in theAegean Sea. Turkey is one of few countries to not have signedUNCLOS.
TheSouth China Sea is the setting forseveral ongoing disputes between regional powers including China, Taiwan, Vietnam, the Philippines, Indonesia, Malaysia and Brunei.
Japan claims an EEZ aroundOkinotorishima, but this is disputed by China, Taiwan, and South Korea, who claim it is an islet which is incapable of generating an EEZ.
China and South Korea debates over the boundaries of EEZs in the East China Sea and Yellow Sea, includingSocotra Rock, a source forterritorial dispute.
TheCod Wars between the United Kingdom and Iceland occurred periodically over many decades until they were resolved with a final agreement in 1976.
In 1992, theCanada–France Maritime Boundary Case, which centred on the EEZ around the French islands of Saint Pierre and Miquelon, was decided by an arbitral tribunal that concurred on the whole with the arguments put forth by Canada. France was awarded 18% of the area it had originally claimed.
In 2009, in a dispute between Romania and Ukraine overSnake Island, the UNInternational Court of Justice decided that Snake Island has no EEZ beyond 12 nautical miles of its own land.[23]
In 2010, a dispute between Norway and Russia about both territorial waters and EEZ with regard to theSvalbard archipelago as it affects Russia's EEZ due to itsunique treaty status was resolved. A treaty was agreed in principle in April 2010 between the two states and subsequently officially ratified, resolving this demarcation dispute.[24] The agreement was signed in Murmansk on 15 September 2010.[25]
In 2014, the Netherlands and Germany resolved an old border dispute regarding the exact location of the border in theDollart Bay.[26][27]
Fisheries management, usually adhering to guidelines set by theFood and Agriculture Organization (FAO), provides significant practical mechanisms for the control of EEZs. Transboundary fish stocks are an important concept in this control.[28]Transboundary stocks arefish stocks that range in the EEZs of at least two countries.Straddling stocks, on the other hand, range both within an EEZ as well as in thehigh seas, outside any EEZ. A stock can be both transboundary and straddling.[29]
Algeria on 17 April 2018 established an exclusive economic zone (EEZ) off its coasts by Presidential Decree No. 18-96 of 2 Rajab 1439 corresponding to 20 March 2018.[30][31] The permanent mission of Spain to the United Nations on 27 July 2018 declared its disagreement with the EEZ announced by Algeria and that the government of Spain indicated its willingness to enter into negotiations with the government of Algeria with a view to reaching a mutually acceptable agreement on the outer limits of their respective exclusive economic zones,[32] The same was done by the Italian mission on 28 November 2018.[33] The two countries indicated that the Algerian measure had been taken unilaterally and without consulting them.
On 25 November 2018, the Algerian Ministry of Foreign Affairs sent an oral note in response to the Spanish protest, explaining that the Algerian government does not recognize the largely exorbitant coordinates contained in Royal Decree 236/2013, which overlap with the coordinates of Presidential Decree n° 18–96 establishing an exclusive economic zone off the coast of Algeria. The Algerian government wished to emphasize that the unilateral delimitation carried out by Spain is not in conformity with the letter of the United Nations Convention on the Law of the Sea and has not taken into consideration the configuration, the specific characteristics, and the special circumstances of the Mediterranean Sea, in particular for the case of the two countries whose coasts are located face to face, as well as the objective rules and relevant principles of international law to govern the equitable delimitation of the maritime areas between Algeria and Spain, in accordance with article 74 of the United Nations Convention on the Law of the Sea. Algeria expressed its willingness to negotiate for a just solution.[34]
On 20 June 2019, a communication from Algeria was sent. It was addressed to the Italian embassy[35] and the Spanish embassy in Algiers[36] to show their eligibility in Algeria's exclusive economic zone.
Australia's exclusive economic zones, including its Antarctic claim
Australia's exclusive economic zone was declared on 1 August 1994, and extends from 12 to 200 nautical miles from the coastline of Australia and itsexternal territories, except where a maritimedelimitation agreement exists with another state.[37][38] To the 12 nautical miles boundary is Australia'sterritorial waters. Australia has the third largest exclusive economic zone, behind France and the United States, but ahead of Russia, with a total area of 8,148,250 square kilometres, which actually exceeds its land territory.
The United NationsCommission on the Limits of the Continental Shelf (CLCS) confirmed, in April 2008, Australia's rights over an additional 2.5 million square kilometres of seabed beyond the limits of Australia's EEZ.[39][40] Australia also claimed, in its submission to the UN Commission on the Limits of the Continental Shelf, additional Continental Shelf past its EEZ from theAustralian Antarctic Territory,[41] but these claims were deferred on Australia's request. However, Australia's EEZ from its Antarctic Territory is approximately 2 million square kilometres.[40]
Canada's exclusive economic zone and territorial waters
Canada is unusual in that its exclusive economic zone, covering 5,599,077 km2 (2,161,816 sq mi), is slightly smaller than its territorial waters.[43] The latter generally extend only 12 nautical miles from the shore but also include inland marine waters such asHudson Bay (about 300 nmi (560 km) across), theGulf of Saint Lawrence and the internal waters of theArctic Archipelago.
In 2020 and 2022, Chile submitted its partial claims to the United Nations Commission on the Limits of the Continental Shelf (CLCS) to extend its maritime continental margin.
The first figure excludes all disputed waters, while the last figure indicates China's claimed boundaries, and does not take into account adjacent powers' claims.[clarification needed]
Croatia proclaimedEcological and Fisheries Protection Zone in 2003, but it was not enforced toward other European Union states especially Italy and Slovenia. The zone was upgraded to EEZ in 2021 together with Italy and Slovenia.[48][49] Territorial waters has 18,981 km2, whileinternal waters located within the baseline cover an additional 12,498 km2, and EEZ covers 24,482 km2 for a total of 55,961 km2.
Exclusive economic zones of France, including its Antarctic territorial claim
Due to its numerousoverseas departments and territories scattered on all oceans of the planet, France possesses the largest EEZ in the world, covering 11,691,000 km2 (4,514,000 sq mi).[51] The EEZ of France covers approximately 7% of the total surface of all the EEZs of the world, whereas the land area of the French Republic is only 0.45% of the total land area of Earth.
Germany declared the establishment of its exclusive economic zone in the North and Baltic Seas on 1 January 1995.[52] The relevant German legal provisions that are applicable within the EEZ include the Maritime Task Act (Seeaufgabengesetz) from 1965, the Maritime Facilities Act (Seeanlagengesetz) from 2017, and prior to that the Sea Facilities Ordinance (Seeanlagenverordnung) from 1997, the Federal Mining Act (Bundesberggesetz) and the Regional Planning Act (Raumordnungsgesetz).
The German EEZ has an area of 32,982 km2. About 70% of the EEZ covers Germany's entire North Sea area, while some 29% encompasses the Baltic Sea area.[53]
Indonesia has the 6th largest exclusive economic zone in the world. The total size is 6,159,032 km2 (2,378,016 sq mi). It claims an EEZ of 200 nautical miles from its shores. This is due to the 13,466 islands of theIndonesian Archipelago.[57] It has the2nd largest coastline of 54,720 km (34,000 mi). The five main islands are:Sumatra,Java,Borneo,Sulawesi, andWestern New Guinea. There are two major island groups (Nusa Tenggara and theMaluku Islands) and sixty smaller island groups.
Since independence, Ireland's territorial waters were limited to 3 nautical miles (5.6 km).[58]In 1964, herterritorial waters were extended to 12 nautical miles (22 km) from the baseline covering an area of 41,000 km2 (16,000 sq mi),[59] although several European countries retained fishing rights between 6–12 nautical miles (11–22 km).[60][61]In 1976, Ireland's exclusive economic zone was extended out to 200 nautical miles (370 km), increasing her maritime area to 450,000 km2 (170,000 sq mi).[62][63][64]In 1996, Ireland ratified theUnited Nations Convention on the Law of the Sea (UNCLOS) which allows her to claim thecontinental shelf out to 350 nautical miles (650 km) from the baseline.[65] Ireland has made claims under UNCLOS for the Porcupine Abyssal Plain in 2005, the seabed of the Celtic Sea and Bay of Biscay in 2006, and also the Hatton Rockall area in 2009.[66] She was awarded the Porcupine Abyssal claim in 2007 adding 39,000 km2 (15,000 sq mi) of seabed to the State's continental shelf.[67] The other two claims are still under discussion with neighbouring states; the Celtic Sea and Bay of Biscay with France, Spain and the United Kingdom; and the Hatton Rockall area with Denmark, Iceland and the United Kingdom.In 2006, Ireland claimed hercontiguous zone out to 24 nautical miles (44 km) from the baseline.[68]
In 2010, an agreement was signed withCyprus concerning the limit of territorial waters between Israel and Cyprus at the maritime halfway point, a clarification essential for safeguarding Israel's rights to oil and underwater gas reservoirs. The agreement was signed in Nicosia by Israeli Infrastructure MinisterUzi Landau and the Cypriot Foreign Minister Markos Kyprianou. The two countries agreed to cooperate in the development of any cross-border resources discovered and to negotiate an agreement on dividing joint resources.
Italy has an EEZ of 541,915 km2 (209,235 sq mi).[55] The country claims an EEZ of 200 nautical miles from its shores, and its three coastlines are theTyrrhenian Sea to the west, theIonian Sea to the south and theAdriatic Sea to the east. Italy's EEZ is limited bymaritime boundaries with neighboring countries to the northwest, east and southeast.
Japan has the world's eighth-largest exclusive economic zone, covering 4,479,674 km2 (1,729,612 sq mi).[69] It claims an EEZ of 200 nautical miles from its shores.
Japan has disputes over its EEZ boundaries with all its Asian neighbors (China, Russia,South Korea, andTaiwan). The above, and relevant maps at the Sea Around Us Project[70][71][72] both indicate Japan's claimed boundaries, and do not take into account the claims of adjacent jurisdictions.
Japan also refers to various categories of "shipping area" – Smooth Water Area, Coasting Area, Major or Greater Coasting Area, Ocean Going Area – but it is unclear whether these are intended to have any territorial or economic implications.
Mexico's exclusive economic zones cover a total surface area of 3,269,386 km2,[55] and places Mexico among the countries with the largest areas in the world.
New Zealand's EEZ covers 4,083,744 km2 (1,576,742 sq mi),[73][74] which is approximately fifteen times the land area of the country. Sources vary significantly on the size of New Zealand's EEZ; for example, a recent government publication gave the area as roughly 4,300,000 km2.[75] These figures are for the EEZ of New Zealand proper, and do not include the EEZs of other territories in theRealm of New Zealand (theCook Islands,Niue,Tokelau, and theRoss Dependency).
The exclusive economic zone ofNorth Korea stretches 200nautical miles from its basepoints in both theWest Sea (Yellow Sea) and theSea of Japan.[76] The EEZ was declared in 1977 after North Korea had contested the validity of theNorthern Limit Lines (NLL) set up after theKorean War as maritime borders.[77] The EEZ has not been codified in law and North Korea has never specified its coordinates, making it difficult to determine its specific scope.[78]
In the West Sea, the EEZ remains unspecified in theKorea Bay because China has not determined its own EEZ in the area.[79] The border between the North Korean and South Korean EEZs in the West Sea cannot be determined because of potential overlap and disputes over certain islands.[80]
In the Sea of Japan, the North Korean EEZ can be approximated to betrapezoidal-shaped.[81] The border between North Korea and Russia's respective EEZs is the only such border that has been determined in East Asia.[82] Here, the EEZ does not cause many problems, even with regards to South Korea, because the sea is not thought to be rich in resources.[81]
The Kingdom of Norway has a large exclusive economic zone of 819,620 km2 around its coast. The country has a fishing zone of 1,878,953 km2, including fishing zones aroundSvalbard andJan Mayen.[83]
In April 2009, the United Nations Commission for the Limits of the Continental Shelf approved Norway's claim to an additional 235,000 square kilometres of continental shelf. The commission found that Norway and Russia both had valid claims over a portion of the shelf in the Barents Sea.[84]
The coast of Pakistan is 1,046 kilometres (650 mi) long, extending fromSir Creek in the east toGwatar Bay in the west and the EEZ extends up to 290,000 square kilometres (110,000 sq mi) which is equivalent to more than 30% of its land area and ranks sixty-sixth in the world by area.
Pakistan had an EEZ of 240,000 square kilometres (93,000 sq mi) before their case was accepted by UNCLCS.Pakistan Navy with the help of the National Oceanographic Organization (NIO) initiated the continental shelf case at ministerial level in 1995.
On 26 Aug 2013, a seven-member sub-commission with members from Japan, China, Mozambique, Kenya, Denmark, Georgia and Argentina was formulated at UNCLCS to evaluate the technical details of Pakistan's case and after a year accepted Pakistan's claim.
On 13 March 2015, UN Commission on the Limits of Continental Shelf (UNCLCS) accepted recommendations for extension of the outer limits of the continental shelf on Pakistan's case so far 80 countries had submitted claims to UNCLCS out of which recommendations of 22 countries including Pakistan had been finalised.
It was a historic event in the country's history when Pakistan became the first country in the region to have its continental shelf extended to 350 nm.
Some of the claimed territories overlapped the Omani claim. It is believed that the verdict in favour of Pakistan was announced after successful negotiation with Oman.
Portugal submitted a claim to extend its jurisdiction over an additional 2.15 million square kilometres of the adjacent continental shelf in May 2009,[89] resulting in an area with a total of more than 3,877,408 km2. The submission, as well as a detailed map, can be found in the Task Group for the extension of the Continental Shelf website.
Spain previously objected to the EEZ's southern border, maintaining that it should be drawn halfway betweenMadeira and theCanary Islands. But Portugal exercises sovereignty over theSavage Islands, a small archipelago north of the Canaries, claiming an EEZ border further south. Spain has no longer disputed the Portuguese claim since 2015.[90][91]
Turkey's EEZ is bordered byGeorgia,Russia,Ukraine,Romania andBulgaria in the Black Sea to the north,Greece in the Aegean Sea to the west, andCyprus andSyria in the Mediterranean Sea to the south. Turkey is one of the few countries to not have signedUNCLOS and disputesGreece's andCyprus' EEZ.
The exclusive economic zones of the United Kingdom in blue, including theBritish Overseas Territories and theCrown Dependencies. The British claim in Antarctica is shown in shaded blue.[93]UK, Ireland, Iceland & Faroes exclusive economic zones
The United States' exclusive economic zone is the second-largest in the world, covering 11,351,000 km2. Areas of its EEZ are located in three oceans as well as theGulf of Mexico, and theCaribbean Sea. Only France, with its widespread administrativedepartments and overseas territories in theNorth Atlantic, theCaribbean, theIndian Ocean, and in extensive island chains of thePacific, has a larger EEZ than the United States.
^The reference gives an approximate figure of 2 million square kilometres for the EEZ claimed by Australia as part of its Antarctic Territory. This is in addition to the 8 million square kilometres total given in the reference. This EEZ is also distinct from the 2.56 million square kilometres of additional continental shelf mentioned in the reference.
^A jointCuba–Haiti Maritime Boundary Agreement signed at Havana in 1977 bilaterally divides the waters between both local nations and Cuba's maritime boundary places the island within Haitian waters and doesn't recognize any local U.S. claim in the area.
