PCB Politburo member Jorge Kolle Cueto asks on 7 March 1967 to inform the Czechoslovak Communist Party, "on behalf of the CC of the Bolivian CP," regarding "the situation in Bolivia… and his recent meeting with Fidel Castro." After four pages of discussion regarding the depressing internal political situation under 1964 coup leader, General René Barrientos, Kolle announced that "the party must necessarily prepare for the possibility of armed struggle in order to participate in the attempt to overthrow the current regime together with other leftist forces."

Rodriguez met with Koucky to clarify misunderstandings which could possibly arise because the reasons were not explained for Cuba’s positions on issues of the international communist movement, and for speeches and statements of some leading Cuban comrade.

This presents evidence of Czechoslovak-Cuban relations forming in 1959, which includes the somewhat sensitive issue of Prague’s attempting to grasp the relationship and balance of power within Havana’s rulers between Fidel Castro’s “July 26th” movement and the traditional, pro-Moscow communist party, the People’s Socialist Party (PSP).
