evidence: Suriname is bordered by the Atlantic Ocean to the north, by French Guiana to the east, by Brazil to the south, and by Guyana to the west. Suriname is involved in territorial disputes with both Guyana and French Guiana that are legacies of colonial rule. The dispute with Guyana centres on the New River Triangle, a 6,000-square-mile (15,600-square-km) area between two tributaries of the Courantyne River in southern Guyana. In addition to claiming the New River Triangle, Suriname also contests its border with Guyana along the Courantyne: Suriname claims sovereignty over the entire river and thus views its west bank as the border, while Guyana claims that the thalweg, or deepest channel of the river, is the boundary. In 2007 a United Nations international tribunal settled another long-standing boundary dispute between the two countries, in which Suriname was awarded one-third of a disputed area of the Caribbean Sea. The area in contention with French Guiana is the 5,000-square-mile (13,000-square-km) region between the Itany and Marouini rivers in the southwestern corner of French Guiana. [...] Suriname’s major rivers flow northward into the Atlantic. They include the Courantyne, which forms part of the boundary with Guyana; the Coppename; the Suriname; and the Maroni, which forms part of the border with French Guiana. Suriname’s most fertile soils occur in the inundated lands reclaimed by diking and drainage (polders), which are principally in the New Coastal Plain.
