However, no demilitarisation plan acceptable to both the countries could be agreed. The countries fought two further wars in 1965 and 1971. Following the latter war, the countries reached the Simla Agreement, agreeing on a Line of Control between their respective regions and committing to a peaceful resolution of the dispute through bilateral negotiations.

The reason for the conflict is the fact that Tuzla island's strategic location gives Ukraine full rights over the main channel in the Strait of Kerch and, thus, the access to the Sea of Azov.

A wide section from the 35th parallel north to one-mile south.	United States	Tennessee  Georgia	Due to an inaccurate measurement in 1818, Georgia claims the correct 35th latitude north, and does so in a chance of a drought, it would have access to the Tennessee River.[61] See Tennessee River#Water rights and border dispute between Georgia and Tennessee.
51,000 acres straddling the 42nd parallel north	United States	California  Oregon	Location errors in an 1868–1870 survey to demarcate the Oregon-California border created a dispute between Oregon and California, which upon statehood had established the 42nd parallel north as its de jure border, based on the 1819 Adams–Onís Treaty between the U.S. and Spain. The dispute continues to this day, as Oregon has about 31,000 acres of California, while California has about 20,000 acres of Oregon.[62] The border should follow the 42nd parallel straight west from the 120th meridian west to the Pacific. Instead it zigzags, and only one of the many surveyor's markers put down in 1868 actually is on the 42nd parallel.[63][64][65]
New Mexico-Texas Panhandle border	United States	Texas  New Mexico	The border was defined as the 103rd meridian but an 1859 survey marked it too far west, mistakenly putting present-day towns of Farwell, Texline, and a part of Glenrio in Texas.

The New Mexico Senate passed a bill to file a lawsuit to recover the strip, but it has not become law.[66] The land and towns are administred by Texas.
parts of Fort Bonifacio	Philippines	Makati  Taguig  Pateros	Disputed since 1983. Taguig claims more than 729 hectares of land in Fort Bonifacio, an area administered by Makati. On August 5, 2013, the Court of Appeals Sixth Division ruled that Makati has legal jurisdiction over the area, thus invalidating Taguig's claim.[67] Taguig has not abandoned its claims and will petition the Court of Appeals to have the decision revoked.[68] Pateros also claims the area and has filed a petition before the Taguig Regional Court Branch 271 in 2012 concerning its claim. Pateros reiterated its claims in 2013 following the decision of the Court of Appeals awarding Makati jurisdiction over the area.[69][70]
Fiat Auto Poland factory and nearest areas	Poland	Tychy  Bieruń	The territory has historically been a part of the town of Bieruń. In years 1975–1991 Bieruń was a part of Tychy. The Fiat Auto Poland (formerly FSM factory remaining in Tychy was a condition of Bieruń's separation. In the 90s, Bieruń has regained the Homera osiedle which was part of the disputed area.[71]

Antarctica

The Antarctic Treaty System, formed on 1 December 1959 and entered into force on 23 June 1961, establishes the legal framework for the management of Antarctica and provides administration for the continent, which is carried out through consultative member meetings. It prevents new territorial claims of all signatories (except U.S and Russia) for as long as the treaty is in force. However, it is not a final settlement; parties can choose to withdraw from the System at any time. Furthermore, only a minority of states have signed it, and it is not formally sanctioned by the United Nations. Thus, Antarctica remains the only part of the planet any (non-signatory) state can still lay claim to as terra nullius (on the grounds of it not having been part of any existing state's legal and effective territory).

Bay of Bengal Maritime Boundary between Bangladesh and India	India Bangladesh	1974	2014	India and Bangladesh had engaged in eight rounds of bilateral negotiations starting 1974 but it remained inconclusive until 2009. In October 2009, Bangladesh served India with notice of arbitration proceedings under the UNCLOS . The Arbitration Tribunal delivered the ruling on 7 July 2014 and settled the dispute.[81]
Indo-Bangladesh enclaves, adverse possessions and undemarcated land boundaries	India Bangladesh	1947	2015	Following Partition of Bengal (1947), the issues of adverse possessions, enclaves and unmarked boundary arose. Inside the main part of Bangladesh, there were 111 Indian enclaves (17,160.63 acres), while inside the main part of India, there were 51 Bangladeshi enclaves (7,110.02 acres). In 1974 Bangladesh approved a proposed treaty, Land Boundary Agreement, to exchange all enclaves within each other's territories, but India did not ratify it. Another agreement was agreed upon in 2011 to exchange enclaves and adverse possessions. With respect to adverse possessions, India received 2,777.038 acres of land and transferred 2,267.682 acres to Bangladesh. India ratified the agreement by constitutional amendment in May 2015.[82]
South Talpatti/New Moore/Purbasha Island	India  Bangladesh	c. 1975	2010	This former dispute over a small island never more than two meters above sea level was contested from the island's appearance in the 1970s to its disappearance, likely due to climate change,[83] in the first decade of the 2000s. Though land disputes no longer exist, the maritime boundary was not settled until 2014.[81][84][85][86]
Sakhalin Island	Russian Empire  Empire of Japan	1845	1875	Japan unilaterally proclaimed sovereignty over the whole island in 1845, but its claims were ignored by the Russian Empire. The 1855 Treaty of Shimoda acknowledged that both Russia and Japan had joint rights of occupation to Sakhalin, without setting a definite territorial demarcation. As the island became settled in the 1860s and 1870s, this ambiguity led to increasing friction between settlers. Attempts by the Tokugawa shogunate to purchase the entire island from the Russian Empire failed, and the new Meiji government was unable to negotiate a partition of the island into separate territories. In 1875 by the Treaty of Saint Petersburg, Japan agreed to give up its claims on Sakhalin in exchange for undisputed ownership of the Kuril Islands. In 1905 under the Treaty of Portsmouth Japan gained Sakhalin to the 60th parallel, but lost it again in 1945.
Pamir Mountains	Tajikistan  People's Republic of China	1877	2011	The Tajik Government ceded 1,158 square kilometres (447 sq mi) to the PRC, while PRC relinquished its 28,000 square miles (73,000 km2) claim over the remaining territory with final ratification of a treaty in January 2011.[87]
Palmas Island (modern-day Miangas Island)	Philippine Islands  Dutch East Indies	1906	1928	Dispute between the United States and the Netherlands over the Palmas island located south of the Philippines, which was then American territory. The Netherlands believed that the islands were part of the Dutch East Indies. The territorial dispute was solved through the Island of Palmas case which decided that the Palmas Island belongs to the Netherlands. Palmas Island, now Miangas Island, is a part of modern Indonesia.
Yalu River (disputed sovereignty of certain islands)[1][note 3]	People's Republic of China  North Korea  South Korea	1949	2005	The allocation to North Korea of all of the large islands in the lower Yalu River, including Pidan and Sindo at the mouth, is now clear.[88] The river's maritime rights remain shared between the two nations.
Shaksgam Valley	Pakistan (still claimed by:  India  China)	1947	1963	Pakistan relinquished its claim to PR China; India did not.
Sinai Peninsula	Israel  Egypt	1967	1982	During the Six-Day War Israel claimed Sinai. It was returned in 1982 under the terms of the 1979 Egypt–Israel Peace Treaty.
Taba	Israel  Egypt	1979	1989	When Egypt and Israel were negotiating the exact position of the border in preparation for the 1979 peace treaty, Israel claimed that Taba had been on the Ottoman side of a border agreed between the Ottomans and British Egypt in 1906 and had, therefore, been in error in its two previous agreements. Although most of Sinai was returned to Egypt in 1982, Taba was the last portion to be returned. The issue was submitted to an international commission. In 1988, the commission ruled in Egypt's favour, and Israel returned Taba to Egypt in 1989.
Turtle Islands	Philippine Islands  North Borneo		1930	Dispute between the United States and the United Kingdom over the Turtle Islands located south of the Philippines, which was then American territory. In a 1930 treaty the United Kingdom acknowledge American sovereignty over the islands and was agreed upon that the British would remain administering the island until the United States express interest to take over control over the islands after a one-year notice. When the Philippines gained full independence from the United States in 1946, the Philippines invoked the treaty and the British turned over the islands to the Philippines in 1947.
West Bank, including East Jerusalem	Israel  Jordan	1967	1988	During the Six-Day War Israel conquered these territories from Jordan. Jordan later renounced the claim on the territory, supporting instead its inclusion in a future Palestine.
Ligitan and Sipadan	Malaysia  Indonesia	1969	2002	The 2002 International Court of Justice ruling awarded both islands to Malaysia, but left unsettled the maritime boundary immediately southwest and west of the islands between Malaysia and Indonesia.
Hawar Islands	Qatar  Bahrain	1971	2001	Formerly disputed between Qatar and Bahrain, it was settled by the International Court of Justice (ICJ) in The Hague. In the June 2001 decision, Bahrain kept the Hawar Islands and Qit'at Jaradah but dropped claims to Janan Island and Zubarah on mainland Qatar, while Qatar retained significant maritime areas and their resources. The agreement has furthered the goal of definitively establishing the border with Saudi Arabia and Saudi-led mediation efforts continue.
Pulau Batek/Fatu Sinai (de)	Indonesia  East Timor	2002	2004	Ceded by Timor-Leste to Indonesia in August 2004.
Saudi Arabia–Yemen border demarcation dispute	Saudi Arabia  Yemen	1934	2000	Settled by the Treaty of Jeddah (2000).

Americas

Alaska boundary dispute	United States  Canada	1821	1903	Disputed between the United States and Canada (then a British Dominion with its foreign affairs controlled from London). The dispute had been going on between the Russian and British Empires since 1821, and was inherited by the United States as a consequence of the Alaska Purchase in 1867. It was resolved by arbitration in 1903 with a delegation that included 3 Americans, 2 Canadians, and 1 British delegate that became the swing vote. By a 4 to 2 vote, the final resolution favored the American position. Canada did not get an outlet from the Yukon gold fields to the sea. The disappointment and anger in Canada was directed less at the United States, and more at the British government for betraying Canadian interests in pursuit of a friendly relationship between Britain and the United States.
Aroostook War	United States British North America	1838	1842	Disputed border between the state of Maine and the provinces of New Brunswick and Lower Canada.

New Hampshire Grants/Vermont	New Hampshire/New York/Vermont	1749	1791	In 1664 King Charles II decided the west bank of the Connecticut River was the eastern boundary of New York, so that that province included all of what later became the state of Vermont. During 1749–64, Governor Benning Wentworth of New Hampshire issued well over a hundred "grants", offering lands for sale west of the river in what would become Vermont. In 1764, King George III attempted to end the dispute by ruling that the region belonged to New York. But New York would not recognize the property claims of numerous settlers whose claims were based on Wentworth's grants, so local governments and militias resisted New York's rule. In 1777, the politicians of the disputed territory declared it independent of New York, Britain, and New Hampshire, calling it the State of Vermont. Vermont existed for 14 years as an unrecognized de facto independent country, considered by New York to be a district in rebellion. Negotiations between New York and Vermont in 1790 removed impediments to Vermont's admission to the Union in 1791.
Delaware Wedge	Delaware  Maryland  Pennsylvania	1750s	1921	A gore created when the borders of the colonies Maryland, Delaware, and Pennsylvania were defined. Dispute over the borders between the three colonies dates to the foundation of each during the middle 17th century. A series of defined lines and arcs were laid out by statute to settle the disputes, the most famous of which was the Mason–Dixon line. The Wedge was left out of all three colonies (and later U.S. states), and remained a matter of dispute until it was formally resolved to assign the Wedge to Delaware in 1921.
Eastern shore of the Narragansett Bay	Colony of Rhode Island and Providence Plantations Plymouth Colony (to 1691) Province of Massachusetts Bay (from 1691)	1636	1898	Claimed by both Rhode Island and Plymouth Colony. Plymouth's claim was inherited by the newly created Province of Massachusetts Bay when the latter was created in 1691 from the merger of earlier Massachusetts Bay and Plymouth Colonies. A royal decree in 1746 assigned the land to Rhode Island, but Massachusetts continued to press its claim until 1898.
New York – New Jersey Line War	New York  New Jersey	1701	1756	Dispute over the southern border of Province of New York and the northern border of the Province of New Jersey. Raiding parties kidnapped and burned crops.
Isla Martín García	Argentina  Uruguay	1879	1973	After the Conquest of the Desert was formally launched in 1879, many indigenous leaders captured were confined there. The island was transferred to Argentine Navy jurisdiction in 1886. The island's distance from the Uruguayan territory is less than two miles, and its jurisdictional status was formally established by the Treaty of Río de la Plata between Uruguay and Argentina on November 19, 1973.
Cordillera del Cóndor-Cenepa River	Peru  Ecuador	1828	1998
Cordillera of the Andes Boundary Case	Argentina  Chile	1881	1902	After the signature of the Boundary treaty of 1881 between Chile and Argentina differing interpretations on whether the highest Andean peaks (favouring Argentina) or the continental divide (favouring Chile) was to be considered the boundary.
Puna de Atacama dispute	Argentina  Chile	1889	1898
Clipperton Island	Mexico  France	1897	1931	Disputed between France and Mexico. On January 28, 1931, King Victor Emanuel, selected as a neutral arbitrator, finally declared Clipperton to be a French possession, and it has remained relatively undisputed ever since.

Río Encuentro-Alto Palena dispute	Argentina  Chile	1913	1966
Laguna del Desierto	Argentina  Chile	1949	1994
Missouri	United States  Confederate States	1861	1865	After the Missouri secession, the State of Missouri was claimed by both the United States and Confederate States until the defeat of the Confederacy in the American Civil War
Border of New Hampshire and Canada	United States  United Kingdom	1783	1842	Ill-defined terms of the Treaty of Paris at the end of the Revolutionary War left the boundary of the state of New Hampshire and Canada in doubt. The lack of a precise definition of the "northwesternmost head of the Connecticut River" as defined by the Treaty of Paris left the land that is now the town of Pittsburg, New Hampshire within the conflicting jurisdiction of both the United States and Great Britain. In 1832 residents of the area established the short-lived Republic of Indian Stream in the area; the minuscule population of the putative nation never exceeded about 300. The boundary was finally settled definitively by the Webster–Ashburton Treaty of 1842.
Sverdrup Islands	Norway  United Kingdom	1928	1930	In 1928 Norway asserted its claim of sovereignty over the Sverdrup Islands. The islands are named after Norwegian explorer Otto Sverdrup, who explored and mapped them from 1898 to 1902 with the vessel Fram, although some were previously inhabited by Inuit people. Sverdrup claimed the islands for Norway, but the Norwegian government did not pursue the claim until 1928. At that point, the Norwegian government raised the claim, primarily to use the islands as bargaining chips in negotiations with the United Kingdom over the status of the Arctic island Jan Mayen and the Antarctic Bouvet Island. On November 11, 1930, Norway ceded the Sverdrup Islands to Canada, in exchange for British recognition of Norway's sovereignty over Jan Mayen.[89]

Bregovo	Bulgaria  Kingdom of Serbia	1885	1886	Bulgaria And Serbia briefly had a war over a small border village called Bregovo and this has been the recognized border ever since then.
Åland Islands	Finland  Sweden	1917	1920	Sweden and Finland argued over the control of the Åland Islands (located between Sweden and Finland). The Åland movement (Ålandsrörelsen) wanted Åland to reunite with its old mother country Sweden (Finland and Åland belonged to Sweden before 1809). The movement gathered signatures from over 7000 inhabitants of legal age at the Åland Islands in 1917 (that was about 96% of the population) - they all supported a union with Sweden. When Finland became independent (December 6, 1917) Sweden wanted a plebiscite about the future of the Åland Islands to solve the problem. Finland refused and argued that the Åland Islands had always been a natural part of Finland - even when Finland was under Swedish rule. Sweden appealed to the League of Nations referring to the right of the population to determine which country they should belong to. After studying the matter closely the League of Nations decided Finland should retain sovereignty over the province but that the Åland Islands should be made an autonomous territory. The Swedish Prime Minister said he didn’t accept the verdict but he also said that Sweden was not going to use military force to get their claims.[93]
Graham Island	Two Sicilies Malta  France  Spain	1831	1831	A dispute between the Kingdom of the Two Sicilies, the British Crown Colony of Malta, the Kingdom of France and the Kingdom of Spain occurred after the volcanic island appeared in 1831. The British were the first to claim the island as part of Malta, and they were followed by the Two Sicilies and France, while Spain expressed their ambitions to control the island. The island disappeared by December 1831 and the dispute stopped. A Sicilian flag was lowered over the now submerged island in 2000 to show Italian claims to the area. It is no longer disputed by Britain, France, Spain or Malta.
Lampedusa	Sicily Malta	1800	1814	The island was controlled by British troops as a de facto part of Malta Protectorate from 1800 onwards. After a British royal commission was sent there in 1812, the new Governor of Malta Sir Thomas Maitland withdrew British troops and the island was returned to Sicily.
Tenedos	Turkey  Greece	1920	1923	On 11 August 1920, following World War I, the Treaty of Sèvres with the defeated Ottoman Empire granted the island to Greece, who joined the war in Allies' side in May 1917. The new Turkish Government of Mustafa Kemal Atatürk, based in Ankara, which was not party to the treaty, overthrew the Ottoman government, which signed but did not ratify the treaty. After the Turkish War of Independence ended in Greek defeat in Anatolia, and the fall of Lloyd George and his Middle Eastern policies, the western powers agreed to the Treaty of Lausanne with the new Turkish Republic, in 1923. This treaty made Tenedos and Imbros part of Turkey, and it guaranteed a special autonomous administrative status there to accommodate the Greeks.
Northern Ireland	United Kingdom  Ireland	1920	1998	Formerly disputed between Ireland and the United Kingdom since partition on 23 December 1920, it was settled by the Good Friday Agreement in 1998, when Ireland amended its constitutional claim. Both countries acknowledged that the territory can join the rest of Ireland if separate referendums in both Northern Ireland and the Republic of Ireland approve of the former's cession.
Pytalovo (Abrene in Latvia)	Russia  Latvia	1991	2007	Pytalovo was part of independent Latvia as Abrene until Latvia was occupied and annexed by the Soviet Union and Abrene was attached to Russian SSR in 1948. Latvia disputed Russian jurisdiction over the region until giving it up in a border treaty with Russia in 2007.
Ivangorod and Pechorsky District	Russia  Estonia	1991	2007	Russia recognized them as a part of Estonia with Treaty of Tartu, 1920. After the fall of the Soviet Union, Russia continued administering it. Some sources argue Estonia has claims in the area.[94][95]
Sevastopol	Russia  Ukraine	1993	1997	On July 28, 1993, one of the leaders of the Russian Society of Crimea, Viktor Prusakov, stated that his organisation was ready for an armed mutiny and establishment of the Russian administration in Sevastopol. In May 1997, Russia and Ukraine signed the Peace and Friendship Treaty, ruling out Moscow's territorial claims to Ukraine.[96]
Black Sea and Snake Island	Ukraine  Romania	2004	2009	In 2004 Romania filed a case to International Court of Justice claiming that Ukraine's Snake Island was an uninhabitable rock under UNCLOS standards and thus not eligible to carry influence over determination of the maritime boundary between the two states. During the Soviet times the island was a small naval station with a lighthouse. In 2007 the Ukrainian parliament approved an establishment of a small hamlet (settlement) there, Bile, as part of Vylkove city Odessa Region. The maritime boundary issue was settled by the International Court of Justice in 2009.
Vilnius Region	Lithuania  Poland	1920	1945	During the Polish-Soviet War Polish armies entered the Vilnius Region which was at the time part of the Soviet Lithuanian-Belorussian Soviet Socialist Republic. In 1920, Polish General Lucjan Zeligowski led a coup and established the Republic of Central Lithuania which was annexed to the Second Polish Republic after the war as part of the historic Polish–Lithuanian Commonwealth and due to ethnic Poles in the region. Lithuania moved its capital to Kaunas while never giving up its claim to Vilnius. The Lithuanians found support in the Soviet Union for their cause signing the Soviet-Lithuanian Mutual Assistance Treaty in 1939. Following the Soviet invasion of Poland, the region came under Soviet control and became part of the Lithuanian SSR after World War II which was followed by a large number of ethnic Poles being deported two times. Following the fall of the Soviet Union and Act of the Re-Establishment of the State of Lithuania the Vilnius region became part of Lithuania again.
