Brazil–Colombia border
The border between Brazil and Colombia is 1,644.2 km (1,021.7 mi) long. The boundary was delimited in two treaties:
- the Vásquez Cobo-Martins treaty of 1907, establishing the line from the Rio Negro northwestward along the Amazon River-Orinoco watershed divide, "then generally southward along various river courses and straight-line segments to the mouth of the Apaporis River",[1] and
- the Tratado de Límites y Navegación Fluvial of 1928, delimiting the Apaporis-Amazon segment of the boundary as a "geodesic line identical to its Brazilian-Peruvian antecedent after Colombia gained undisputed sovereignty over the area".[1]
The border between Brazil and Colombia has been an important transit point for cocaine.[2] In August 2000, Brazilian President Fernando Henrique Cardoso established a $10 million "Plan Cobra" to secure the border against narcotics traffickers moving into the unpatrolled upper Amazon River basin.[3]
