According to these archives, other countries, such as Peru, cooperated by providing intelligence information in response to requests from the security services of the Southern Cone nations. While Peru had no representatives at the secret November 1975 meeting in Santiago de Chile, there is evidence of its involvement. For instance, as late as June 1980, Peru was known to have collaborated with Argentine agents of 601 Intelligence Battalion in the kidnapping, torture and "disappearance" of a group of Montoneros living in exile in Lima. Brazil signed the agreement later (June 1976), but refused to engage in actions outside Latin America.
