evidence: Suriname is bordered by the Atlantic Ocean to the north, French Guiana to the east, Brazil to the south, and Guyana on the western edges. As a result of colonial control, Suriname is embroiled in territorial disputes with both Guyana and French Guiana. The New River Triangle, a 6,000 square mile (15,600 square km) region in southern Guyana between two tributaries of the Courantyne River, is the focal point of the dispute with Guyana. Along with claiming the New River Triangle, Suriname also disputes its border with Guyana along the Courantyne. Suriname asserts control over the entire river and regards its west bank as the border, but Guyana asserts that the thalweg, or deepest channel of the river, is the border. Another lengthy border dispute between the two nations was resolved in 2007 by a United Nations international tribunal, and Suriname was given one-third of the disputed Caribbean Sea region. The 5,000 square mile (13,000 square km) region in French Guiana's southwest between the Itany and Marouini rivers is the area that is in dispute with that country. [...] Major rivers of Suriname pour into the Atlantic from the north. The Maroni, which forms part of the border with French Guiana, the Coppename, the Suriname, and the Courantyne, which is part of the border with Guyana, are among them. The most productive soils in Suriname are found in the flooded areas that have been reclaimed by diking and drainage (polders), which are mostly on the New Coastal Plain.
