Following the coup d'état of Leguía by troops under the command of Luis Miguel Sánchez Cerro, the treaty was made public and caused much anger among the Peruvian population, which perceived that the treaty awarded Colombia a section of Peruvian territory. This dispute over the Amazon region controlled by Leticia would eventually cause a short war between Colombia and Peru during 1932 and 1933. The conflict over Leticia, which was populated by both Peruvian and Colombian colonists, was resolved after Sanchez Cerro was assassinated and the new Peruvian president Óscar R. Benavides accepted the Rio de Janeiro Protocol which upheld the Salomón–Lozano Treaty and finally put an end to the border disputes between Colombia and Peru.
