Brazil-Colombia border

From Wikipedia, the free encyclopedia

The border between Brazil and Colombia is 1644,2 km long. The boundary was delimited in two treaties:

  • the Treaty of Bogotá 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 Rio Apaporis"[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".[2]

The border between Brazil and Colombia is the most important cocaine smuggling zone of the world.[3]
