The Asociación Latinoamericana de Integración (the Latin American Integration Association; known as ALADI or, occasionally, by the English acronym LAIA) is a Latin American trade integration association, based in Montevideo. Its main objective is the establishment of a common market, in pursuit of the economic and social development of the region. Signed on August 12, 1980, the Montevideo Treaty is an international legal framework that establishes and governs the Latin American Integration Association. It sets the following general guidelines regarding trade relations between signatory countries: pluralism, convergence, flexibility, differential treatment and multiplicity.

The Latin American Free Trade Association (LAFTA) was created in the 1960 Treaty of Montevideo by Argentina, Brazil, Chile, Mexico, Paraguay, Peru, and Uruguay. The signatories hoped to create a common market in Latin America and offered tariff rebates among member nations. LAFTA came into effect on January 2, 1962. When the trade association began, it had seven members and its main goal was to eliminate all duties and restrictions on the majority of their trade within 12 years. By the late 1960s, the area of LAFTA had a population of 220 million and produced about $90 billion of goods and services annually. It also had an average per capita gross national product of $440.
