Another dispute was created after the signing of the Salomón–Lozano Treaty in March 1922 by the governments of Colombia and Peru, which at that time was ruled by Augusto B. Leguía. The treaty, which was kept secret, set the boundary between Peru and Colombia as the Putumayo River, with the exception of a small strip of land controlled by the city of Leticia that would connect Colombia to the main flow of the Amazon River. With that, Colombia effectively recognized Peruvian control of the rest of the disputed region south of the Putumayo River.
