> The declassified U.S. documents reveal CIA recruitment of agents within the upper echelons of the Mexican government between 1956 and 1969. The informants used in this secret program included President Gustavo Díaz Ordaz and future President Luis Echeverría. The documents detail the relationships cultivated between senior CIA officers, such as chief of station Winston Scott, and Mexican government officials through a secret spy network code-named "LITEMPO." Operating out of the U.S. Embassy in Mexico City, Scott used the LITEMPO project to provide "an unofficial channel for the exchange of selected sensitive political information which each government wanted the other to receive but not through public protocol exchanges."

Keep in mind that from the Mexican side the relationship with the US is very difficult to manage and has to be done carefully and sharing of intelligence is a way to keep the US at a healthy distance.
Most important to highlight the systemic structure of these problems.
