Bulgarian Minister of Foreign Affairs, Peter Mladenov reports on North Korean Foreign Minister, Kim Yeong-nam's visit and discussion with Todor Zhivkov, concerning North Korea's "South-South" initiative for economic cooperation between developing countries.

North Vietnamese Deputy Prime Minister and Politburo member Le Thanh Nghi recounts his discussions with socialist leaders in the summer of 1965, just as the war in the south was heating up.

Todor Zhivkov, First Secretary of the Bulgarian Communist Party, reports on his meeting with Kim Il Sung. Zhivkov and Kim discussed global detente and the Cold War, Chinese-North Korean relations, collective security in Asia, North Korea's views of COMECON, Korean unification, and factionalism in the Korean Workers' Party.

Todor Zhivkov summarizes his official and private talks about Korean unification with Kim Il Sung during Kim's visit to Bulgaria in June 1975.

Following the end of the inter-Korean dialogue, Zhivkov observes increased antagonism in the rhetoric of the North Koreans regarding unification paralleling the increasing tension between the two Koreas.

This letter encloses a translated copy of an "Information for the Central Committee of the Bulgarian Communist Party about the Talks between Comrades Todor Zhivkov and Kim Il Sung during the Visit of the DPRK Party and Government Delegation to Bulgaria from 2 to 5 June 1975." In it is discussed both Kim Il Sung's remarks on Korean unification both officially and privately with Comrade Todor Zhivkov. Essentially in both cases Kim makes the argument that the path of military reunification is largely closed off due to the superior military presence of both South Korean and American forces, and instead discusses the details of achieving peaceful reunification by swelling up internal divisions within South Korea, forcing the withdrawal of American forces, and isolating the Park Chung Hee regime internationally.
