The Colombia–Peru border is a 1,626 kilometres (1,010 mi) long continuous international border separating the territories of the two South American countries. It was originally established by the Salomón-Lozano Treaty of 24 March 1922 and then by the Río de Janeiro Protocol of 24 May 1934, which ended the Colombia-Peru War. Both agreements establish the border at the Putumayo River, with the exception of the Amazon Trapeze, located between the Putumayo and Amazon rivers, which is under the sovereignty of Colombia.[1][2][3]
Border layout
According to these treaties, the boundaries between Colombia and Perú are as follows:[2]
The border is defined as:
From the confluence of the Güepí and Putumayo rivers, between Peru, Ecuador and Colombia, downstream along the Putumayo River, to the mouth of the Yaguas River.
A straight line drawn from the mouth of the Yaguas River, in Putumayo, to the mouth of the Atacuari River, in the Amazon.
The Amazon River, downstream, following its course, to the mouth of the San Antonio ravine, where the border with Brazil begins.
