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.

During a trip from Orneta to Katowice, Raul Castro and Zenon Kliszko had conversation on the following topics: (1) assessment of the position of the Italian Communist Party, (2)assessment of the position of the Romanian Workers’ Party, (3) the UPSR and other Communist Parties in Asia, and (4) the Matter of a Former Member of the National Leadership UPSR – J. Ordoqui. For the Polish side, the program of the Italian Communist Party is not clear, particularly with regard to the question of establishing a uniform workers’ party.

Comrade Kliszko presents Liu Ningyi with a letter from six socialist countries calling for a conference to discuss aid and coordination in Vietnam in response to "American imperialism." He urges China to rally against this common enemy, despite the ideological differences dividing the socialist nations. Liu responds harshly both to the proposal and to Comrade Kliszko's statement, arguing China "did not want anything to do with a revisionist clique of the Soviet Union’s leadership and its lackeys."
