French Guiana–Suriname

After centuries of dispute, France, on behalf of its overseas territory of French Guiana, and Suriname, a former Dutch colony, agreed to a boundary delimitation in 2021. The two States established a digital borderline for approximately two-thirds of its length (364 km or 226 miles) along the Maroni and Lawa Rivers. Sovereignty for hundreds of islands was determined.

One remaining dispute, leftover from colonial disagreements, is currently being negotiated by the bilateral boundary commission. There has been a history of conflict over which tributary of the Lawa River the boundary follows to the tripoint with Brazil. The Netherlands, and now Suriname, contends that the boundary follows the Marouini River to the east, while France asserts that the border follows the Litani River and Coulé-Coulé Creek to the west.
