As part of this treaty, the border town of Leticia and its surrounding area was ceded from Peru to Colombia, giving Colombia access to the Amazon River. After months of diplomatic negotiations, the governments accepted mediation by the League of Nations, and their representatives presented their cases before the Council. On 1 September 1932, business leaders from Peruvian rubber and sugar industries who had lost land, as a result, organised an armed takeover of Leticia. At first, the Peruvian government did not recognise the military takeover, but President of Peru Luis Sánchez Cerro decided to resist a Colombian re-occupation. The Peruvian Army occupied Leticia, leading to an armed conflict between the two nations. A provisional peace agreement, signed by both parties in May 1933, provided for the League to assume control of the disputed territory while bilateral negotiations proceeded. In May 1934, a final peace agreement was signed, resulting in the return of Leticia to Colombia, a formal apology from Peru for the 1932 invasion, demilitarisation of the area around Leticia, free navigation on the Amazon and Putumayo Rivers, and a pledge of non-aggression.
