French Guiana west of the Marouini River | France Suriname | |
Tigri Area east of the Upper Courantyne River | Guyana Suriname | The Tigri Area (Dutch: Tigri-gebied) is a wooded area that has been disputed since around 1840 by Suriname and Guyana. It involves the area between the Upper Corentyne River (also called New River), the Coeroeni River and the Kutari River. This triangular area in Guyana is known as the New River Triangle. In 1969 the conflict became tense, and since then the Tigri Area has been controlled by Guyana, but claimed by Suriname. In 1971 both governments in Trinidad agreed that they continue talks over the border issue and withdraw their military forces from the disputed Triangle. Guyana has never complied with this agreement. |
Isla Brasilera/Ilha Brasileira | Brazil Uruguay | Uruguayan officials claim that the island falls under their Artigas Department (the UN does not officially recognize the claim) |
Isla Suárez/Ilha de Guajará-mirim | Bolivia Brazil | An island in the river Rio Mamoré that serves as a border between Bolivia and Brazil, alongside the other 80 islands that are not assigned to any country. Isla Suárez is geographically closer to Bolivia, however economically dependent on the Brazilian city of Guajará-Mirim. Both countries signed a treaty in 1958 that keeps the island in a status quo |
Southern Patagonian Ice Field | Argentina Chile | From Mount Fitz Roy to Cerro Murallón the border remains undefined, while on the zone of Murallón and Cerro Daudet both countries already defined a border in 1998, but they difer on their respective cartography. |
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 the 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).

Ashmore and Cartier Islands | Australia Indonesia | Indonesia argues that the islands, known in Indonesian as Kepulauan Pasir, were first discovered and inhabited by local fishermen from Lesser Sunda Islands, which were then part of Dutch East Indies.[33][34][35] |
Aarsal, Deir El Aachayer, Kfar Qouq, Mazraat Deir al-Ashayer, Qaa, Qasr and Tuffah | Lebanon Syria | Aarsal, Deir El Aachayer, Kfar Qouq, Qaa, Qasr and Tuffah are under Lebanese control while Mazraat Deir al-Ashayer is under Syrian control. |
Shatt al-Arab | Iran Iraq | The Shatt al-Arab dispute was a territorial dispute that took place in the Shatt al-Arab region from 1936 until 1975. The Shatt al-Arab was considered an important channel for the oil exports of both Iran and Iraq. In 1937, Iran and the newly independent Iraq signed a treaty to settle the dispute. In the 1975 Algiers Agreement, Iraq made territorial concessions—including the Shatt al-Arab waterway—in exchange for normalized relations. |
Abu Musa | Iran United Arab Emirates | In 1971, the Iranian navy took control of Abu Musa, while it still belonged to the Emirate of Sharjah, now in the United Arab Emirates. The Emirate of Sharjah later joined the United Arab Emirates, who therefore inherited an official claim on Abu Musa. As of 2022, this is an ongoing dispute, with Iran in control of the island since its takeover in 1971. |
Greater and Lesser Tunbs | Iran United Arab Emirates | Closely related to the dispute over Abu Musa, Iran had also around the same time seized control over the Greater and Lesser Tunbs while they were under control by the Emirate of Ras al-Khaimah. When Ras al-Khaimah joined the United Arab Emirates, the dispute was also inherited to the UAE. The dispute is still ongoing as of 2022. |
Bukit Jeli | Thailand Malaysia | |
Azad Kashmir and Gilgit-Baltistan | Pakistan India | Administered by Pakistan and claimed by India. Part of the Kashmir conflict. |
Jammu and Kashmir and Ladakh | India Pakistan | Part of the Kashmir conflict. Both India and Pakistan claim the former independent princely state of Jammu and Kashmir (including Ladakh, which India split off from the portion that it controls in 2019), leading to the Indo-Pakistani war of 1947. A UN-mediated ceasefire put a halt to the conflict in January 1949. The UN resolution called for both the countries to demilitarise the region, following which a plebiscite would be held. 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. An armed insurgency broke out in 1989 in the Indian administered part of Kashmir, demanding "independence". Pakistan is believed to provide arms and training to the militants.[36][37][38][39] |
Junagadh and Manavadar | India Pakistan | India annexed Junagadh (located within Gujarat) in 1947, shortly after the partition of India. Junagadh was one of the many princely states that was contested between India and Pakistan; Manavadar was a vassal state of Junagadh, alongside Babariawad and Mangrol. The dispute fell into obscurity over the next few years due to the prioritisation of the Kashmir conflict. In August 2020, Pakistan revived the decades-old dispute by highlighting "Junagadh and Manavadar" as a part of Pakistan in an official map on its "Survey of Pakistan" website. The dispute is largely symbolic in nature and is politically connected to the dispute over Kashmir, which is much more important to Pakistan.[40][41] |
David Gareja monastery complex boundary dispute | Georgia Azerbaijan | Since the monastery complex is located on the border between Georgia and Azerbaijan, both parties have entered a dispute over which nation it belongs to. |
Doi Lang | Myanmar Thailand | |
Fasht ad Dibal and Qit'at Jaradah | Bahrain Qatar | These are island territories that are disputed between Qatar and Bahrain. Controlled by Bahrain, Qatar argues that the territories do not qualify as "islands" and hence are not covered by the International Court of Justice ruling (2001–2003) that handed them over to Bahrain. |
Several areas in the Fergana Valley | Kyrgyzstan Tajikistan Uzbekistan | Kyrgyzstan: Barak is a tiny Kyrgyz village in the Fergana Valley region (where Kyrgyzstan, Tajikistan and Uzbekistan meet). In August 1999, the area around Barak was occupied by Uzbekistan. Barak became a de facto enclave only 1.5 km from the shifted main border.[42][43][44] (Map) In August 2018, Kyrgyz and Uzbek authorities agreed to a land swap that would eliminate the exclave, claiming that the exchange process may take up to two years.[45] As of a February 2022 report, only 85 percent of the land was traded, and then work stopped, leaving only 15 families to preserve Barak.[46] Tajikistan: There are three Tajik exclaves, all of them in the Fergana Valley. One of them, the village of Sarvan, is surrounded by Uzbek territory, whereas the remaining two, the village of Vorukh and a small settlement near the Kyrgyz railway station of Kairagach, are each surrounded by Kyrgyz territory. Uzbekistan: There are four Uzbek exclaves, all inside Kyrgyz territory in the Fergana Valley. Two of them are the towns of Sokh and Shakhimardan and the other two the tiny territories of Chon-Qora and Jani-Ayil. There may be a fifth Uzbek exclave inside of Kyrgyzstan.[47] Most of the border in the area is still not demarcated. |
Isfara Valley | Kyrgyzstan Tajikistan | In April 2021, a violent disagreement broke out in Isfara Valley, supposedly over the installation of surveillance cameras by the Tajiks at a water intake station of a reservoir.[48] It escalated into an armed conflict that reached hundreds of civilian casualties. The area's dispute is mainly due to faulty allocation of resources during and after the breakup of the Soviet Union and its republics, leading to tense relations between nations over said allocation of resources, namely water. |
Ambalat | Indonesia Malaysia | |
Golan Heights | Israel Syria | Syrian territory captured by Israel in 1967 (the Six-Day War), and unilaterally annexed by Israel in 1981. In 2008, a plenary session of the United Nations General Assembly voted by 161–1 in favor of a motion on the "occupied Syrian Golan" that reaffirmed support for UN Resolution 497; United Nations, December 5, 2008). During the Syrian civil war period, Syrian Arab Republic had lost direct control of the Eastern Golan areas and retreated from cease-fire line with Israel (in favor of various rebel and Jihadist groups), though did regain the area in 2018. |

Artsvashen exclave of Gegharkunik province, de jure part of Armenia; Karki exclave of Nakhichevan Autonomous Republic, Yukhari Askipara and Barkhudarli, both exclaves of Qazakh Rayon de jure part of Azerbaijan; "Yaradullu" is controlled by Azerbaijan along with occupying the much larger de jure Armenian territory surrounding it. | Armenia Azerbaijan | Azerbaijan and Armenia have controlled these areas as part of the wider Nagorno-Karabakh conflict. |
Khuriya Muriya Islands | Oman Yemen | |
Korean Peninsula | North Korea South Korea | The Democratic People's Republic of Korea administers North Korea, but Article 1 of the Constitution of North Korea reads: "The Democratic People's Republic of Korea is an independent socialist State representing the interests of all the Korean people." The Republic of Korea administers South Korea, but Article 3 of the Constitution of South Korea reads: "The territory of the Republic of Korea shall consist of the Korean peninsula and its adjacent islands." |
South Kuril/Chishima Islands (Northern Territories), Kuril/Chishima Islands, and South Sakhalin[1][51] | Russia Japan | After the end of World War II, the Japanese government renounced its claims of the sovereignty over the Kuril Islands (except for a few islands in the south) and South Sakhalin in The Treaty of San Francisco.[52] However, since the Soviet Union did not sign that treaty and the treaty did not explicitly approve Russian sovereignty over these areas, the Japanese government has stated that attribution of these regions has not yet been determined. Therefore, they do not recognize Soviet rule in those areas (current the Russian Federation).[53] For this reason, these lands are shown as No Man's Land in white color on most official maps in Japan. |
Dokdo/Takeshima | South Korea North Korea Japan | Formally incorporated into Japan in 1905 and was also declared Japanese territory under the San Francisco Peace Treaty that took effect in 1952. Since 1952, however, Korea has been in effective control of the island. |

Noktundo | Russia South Korea | In 1990, the former Soviet Union and the Democratic People's Republic of Korea (North Korea) signed a border treaty which made the border run through the center of the Tumen river, leaving Noktundo in Russia. South Korea refused to acknowledge the treaty. |
"Pedra Branca"; several islets at the eastern entrance to the Singapore Strait | Singapore Malaysia | The International Court of Justice rendered its decision on 23 May 2008 that sovereignty over Pedra Branca belongs to Singapore; sovereignty over Middle Rocks belongs to Malaysia. It said sovereignty over South Ledge would remain disputed until the states could determine the ownership of the territorial waters in which it is located.[54] |

Qaruh and Umm al Maradim | Kuwait Saudi Arabia | |
Part of Sabah (North Borneo) | Malaysia Philippines | The Philippines retains a claim on the eastern part of Sabah (see North Borneo dispute) on the basis claimed by the Government of the Philippines that the territory is only leased by the former Sultanate of Sulu to British North Borneo Company, of which the Philippines argued that it should be the successor state of all Sulu past territories.[1] |

Crimea (including Sevastopol) | Russia Ukraine | In 2014, Russia annexed the Crimean Peninsula in a disputed referendum. Russian ownership of Crimea is recognized by a minority of countries.[60] The General Assembly Resolution 68/262 by votes 100 "in favor", 11 "against", 58 "abstained" and 24 abstentions noted that Crimea was part of Ukraine. Nonetheless, Crimea is practically a de facto subdivision of Russia as most of the control is in Russia's hands.[61] Russia and Ukraine both divide Crimea into two subdivisions, including a "republic" (Ukraine's Autonomous Republic and Russia's Republic) and the independent city of Sevastopol (Ukraine's "special city" and Russia's "federal city"). |

As much as a 2,821 square kilometres (1,089 sq mi) area in and around the Ibiapaba mountain range | Brazil | Ceará Piauí | This dispute originated in an 1880 imperial decree. In 1920 a solution to the dispute was arbitrated but in practice it was never carried out. In 2008 there were new attempted negotiations, but they broke down in 2011, and as of 2013 it is pending either a supreme court decision, a referendum or a possible mutual agreement.[90] |

The kebeles of Adaytu, Undufo, and Gedamaytu | Ethiopia | Afar Somali Region | The three towns have long been fought over by the Issa clan Somalis, backed by the Somali Region government, against the Afar Region and Afar-allied militants. In 2014, the border between the two regions was redrawn by the federal government, placing the three ethnic Somali towns inside the Afar region. In the same year, the presidents of the two regions signed an agreement recognizing the three kebeles as special kebeles within the Afar Region which was rejected by the local people.[93][94] Later in 2019, the Somali Region withdrew from the agreement, claiming the three areas again.[95] The conflict between the two people has also spilled over into Djibouti.[96] |

Parts of Fort Bonifacio | Philippines | Makati Taguig Pateros | Disputed since 1983.

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.[108] |
A wide section from the 35th parallel north to 2 kilometres (1.2 mi) south. | United States | Tennessee Georgia | Based on an inaccurate measurement in 1818, the Georgia–Tennessee border does not match the 35th parallel, which was defined as the border by Congress in 1796. Georgia's claim would give it access to the Tennessee River and mitigate the impact of a severe drought.[109] See Tennessee–Georgia water dispute. |
California–Oregon border | Oregon California | Location errors in an 1868–1870 survey to demarcate the California–Oregon 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 there are about 31,000 acres (13,000 ha) of disputed territory administered by Oregon, and about 20,000 acres (8,100 ha) administered by California.[110] 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.[111][112][113] | |
New Mexico–Texas Panhandle border | 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. New Mexico's draft constitution used the 103rd meridian as intended. The New Mexico Senate passed a bill to file a lawsuit to recover the strip, but it has not become law.[114] The land and towns are administered by Texas. | |

Part of the Kahemba region | Angola Democratic Republic of Congo | 2007 | Following a March 2007 report on the disputed area on the joint border in the Kahemba region, the Congolese interior minister admitted the territory was in fact part of Angola and agreed to send a technical team to demarcate the border along colonial era lines.[120] The countries agreed to end the dispute in July 2007.[121] | |
Lété Island and nearby islands in the Niger River | Niger Benin | c. 1960 | 2005 | In 2005 the International Court of Justice awarded Lété and 15 of the other disputed islands to Niger, and the remaining nine islands to Benin.[122] |
Sedudu | Botswana Namibia | 1890 | 1999 | In 1999 the International Court of Justice awarded Sedudu to Botswana, ending the Namibian claim.[123] |
Tindouf Province | Algeria Morocco | 1956 | 1970 | Morocco ( influenced by the Greater Morocco ideology ) claimed that both Tindouf and Béchar historically belong to Morocco after they were annexed by France for the French colony of Algeria. Algeria wasn't supporting the claims since one of the FLN's primary objectives was to prevent France from splitting the strategic Sahara regions from a future Algerian state. It was therefore disinclined to support Morocco's historical claims to Tindouf and Bechar or the concept of a Greater Morocco. King Hassan II of Morocco visited Algiers in March 1963 to discuss the undefined borders, but Algeria's President Ahmed Ben Bella believed the matter should be resolved at a later date. Ben Bella's fledgling administration was still attempting to rebuild the country after the enormous damage caused by the Algerian War. Algerian authorities suspected that Morocco was inciting the revolt, while Hassan was anxious about his own opposition's reverence for Algeria, escalating tensions between the nations. These factors prompted Hassan to begin moving troops towards Tindouf leading to the Sand war which ended with no territorial changes.[124][125][126] |

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. |
