Conversation for the record between Zhivkov and Castro during a four-day-long state visit of the Cuban leader to Bulgaria. Among the main issues discussed was the state of economic development in both countries, their relations with Albania, China, Romania and Yugoslavia; the Cuban foreign policy in Africa and the Caribbean; the civil war in Angola; the battle for the Third World.

According to the State Security Committee chair, Angel Solakov, there has been a major shift in the policies of the West towards the Soviet bloc. While during the 1950s military face-off was often considered an option, in the late 1960s such possibility has been largely ruled out. Consequently the US and their allies in Western Europe are focusing their efforts on fighting socialism around the world through peaceful means, such as strengthening economic and cultural ties with the Soviet bloc countries. This calls for a change in the strategy of the State Security Committee intelligence operations. Solakov also reports on the anti-Soviet activities of the Chinese and Albanian intelligence services across Europe.

The Minister of Internal Affairs, Dimitar Stoyanov, reports on the coverage in the Western media of the alleged repressions against six Bulgarian dissidents who sent an open letter to the 1986 CSCE Meeting in Vienna. The letter claimed that Bulgaria does not comply fully with the Helsinki Accords on Human Rights of 1975. The Minister reports that although some measures have been taken to neutralize the activities of this particular dissident group, the official investigation has been suspended as there was a risk of further tarnishing Bulgaria’s image abroad.
