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

Nepal-China: China may have constructed 11 buildings in Nepal’s Humla region in 2021

Nepal-India: joint border commission continues to work on contested sections of boundary with India, including the 400 sq km dispute over the source of the Kalapani River; the Kalapani issue resurfaced in November 2019 when India issued a new map showing the contested area within India’s borders and then built a new road in the region through Lipulekh pass, an area controlled by India but claimed by Nepal; Nepal countered by amending its constitution and issuing its own map showing the disputed area within its borders; the countries prime ministers briefly discussed the border dispute in April 2022; India has instituted a stricter border regime to restrict transit of illegal cross-border activities

Zambia-Angola: because the straight-line segments along the left bank (Zambian side) of the Cuando/Kwando River do not conform with the physical alignment of the unstable shoreline, Zambian residents in some areas have settled illegally on sections of shoreline that fall on the Angolan side of the boundary

Zambia-Democratic Republic of Congo(DRC): boundary commission continues discussions over Congolese-administered triangle of land on the right bank of the Lunkinda River claimed by Zambia near the DRC village of Pweto

Zambia-Tanzania: some drug smuggling may take place across the Zambia-Tanzania border; there are no known current territorial issues, as both states have continued to recognize the colonial boundaries last modified in 1937; the boundary in Lake Tanganyika remains undefined.

Zambia-Zimbabwe: in 2004, Zimbabwe dropped objections to plans between Botswana and Zambia to build a bridge over the Zambezi River, thereby de facto recognizing a short, but not clearly delimited, Botswana-Zambia boundary in the river; in May 2021, Botswana and Zambia agreed in principle to let Zimbabwe be a partner in the bridge project as it enters its lasts phase
