Ethiopia-Eritrea: Eritrea and Ethiopia agreed to abide by the 2002 Eritrea-Ethiopia Boundary Commission's (EEBC) delimitation decision, but neither party responded to the revised line detailed in the November 2006 EEBC Demarcation Statement

Ethiopia-Somalia: the undemarcated former British administrative line has little meaning as a political separation to rival clans within Ethiopia's Ogaden (populated largely by ethnic Somalis) and southern Somalia's Oromo region; the Somalia-based terrorist group al-Shabaab has conducted cross-border assaults into Ethiopia as recently as 2022

Ethiopia-South Sudan: while border clashes continue in the al-Fashqa (Fashaga) area, the US views the 1902 boundary treaty between Ethiopia and Sudan as being in force

Ethiopia-Sudan: Ethiopia's construction of a large dam (the Grand Ethiopian Renaissance Dam) on the Blue Nile in northern Ethiopia since 2011 has become a focal point of relations with Egypt and Sudan; Egypt has described the giant hydroelectric project as an existential threat because of its potential to control the flow of the river that is a key source of water for the country; Ethiopia completed filling the dam in 2023

Cambodia-Laos: Cambodia is concerned that Laos' extensive upstream dam construction will affect Cambodian waters downstream

Cambodia-Thailand: Cambodia and Thailand have agreed to maintain peace along the border regardless of the decision of the International Court of Justice (ICJ) over territorial dispute near Cambodia's Preah Vihear Temple; the ICJ decision of 11 November 2013 determined that Cambodia had sovereignty over the whole territory of the promontory of Preah Vihear; the border disputes do not involve large amounts of territory, and most of the issues were settled by the Nov. 11, 2013 ICJ ruling

Cambodia-Vietnam: issues include casinos built in Cambodia near the border (gambling and prostitution); narcotics (criminals, crime, and abuse); trafficking of women and children, petrol smuggling into Cambodia from Vietnam, illegal logging, and illegal migration

Suriname-Brazil: none identified

Suriname-France (French Guiana): in March 2021, Suriname and France signed an agreement to establish their border along the Maroni River and its tributary the Lawa River and to cooperate in combatting illegal gold mining; however, the area further south between the Litani and Marouini Rivers is still disputed, with Suriname claiming the border is along the Marouini to the east and France arguing it is along the Litani River to the west

Suriname-Guyana: the two countries dispute the territory between two rivers, known as the New River Triangle, with Suriname contending that the New River (also called the Upper Corentyne) to the west marks their common border, while Guyana asserts that the Kutari River to the east forms the border; each side claims that their river is the source of the Corentyne River that forms a border further north between the two countries; the Permanent Court of Arbitration settled the maritime boundary between Suriname and Guyana in 2007 in an area with potentially substantial oil reserves
