In a conversation between Kliszko and Raul Castro, a referral was made to the position assumed by the Minister of Industry in Cuba, Ernesto Guevara, at the economic seminar of Afro-Asian countries in Algeria in February 1965. Castro stated that he was not prepared to discuss the essence of the issue, e.g. the extent of aid from socialist countries to developing countries, but he felt Guevara's comments were extreme and out-of-place at the seminar.
