Bolivia-Peru: despite tariff-free access to ports in southern Peru and northern Chile, Bolivia persists with its long-standing claims to regain sovereign access to the Pacific Ocean; smuggling of archaeological artifacts from Peru to Bolivia, illegal timber and narcotics smuggling, human trafficking, and falsified documents are current issues 

Bolivia-Brazil: the Roboré Accord of March 29, 1958 placed the long-disputed Isla Suárez/Ilha de Guajará-Mirim, a fluvial island on the Río Mamoré, between the two towns of Guajará-Mirim (Brazil) and Guayaramerin (Bolivia), under Bolivian administration but did not resolve the sovereignty dispute

Singapore-Indonesia: Indonesia and Singapore continue to work on finalization of their 1973 maritime boundary agreement by defining unresolved areas north of Indonesia's Batam Island; subsequent treaties were signed in 2009 (ratified in 2010) and 2014 (ratified in 2017) settling the two countries’ boundaries in the Singapore Strait

Singapore-Malaysia: disputes with Malaysia over territorial waters, airspace, the price of fresh water delivered to Singapore from Malaysia, Singapore's extensive land reclamation works, bridge construction, and maritime boundaries in the Johor and Singapore Straits; in 2008, the International Court of Justice awarded sovereignty of Pedra Branca (Pulau Batu Puteh/Horsburgh Island) to Singapore, and Middle Rocks to Malaysia, but did not rule on maritime regimes, boundaries, or disposition of South Ledge, which is only visible at low tide

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
