Agreement between the Soviet KGB and Czechoslovak Ministry of the Interior from the summer of 1978 to 1980

In order to combat the perceived threat of hostile, foreign special agents operating on Soviet and Czechoslovak territory, the two parties agree to centralize their efforts to ensure the security of the two countries. In order to counter the special agents of capitalist countries and preserve the security of state secrets, the two parties decide to exchange counter-intelligence activity on subversive activity in Czechoslovakia, the Soviet Union and other socialist states. The two parties agree to focus on citizens of capitalist countries such as the United States, England, France and other NATO member nations and citizens of the People's Republic of China and the German Democratic Republic in their intelligence efforts. Specifically, the parties agree to monitor citizens of these countries working in Czechoslovakia and the Soviet Union and people working for representative agencies of the aforementioned countries. Also being monitored are Czechoslovak and Soviet citizens returning from capitalist or developing countries, corresponding with people in capitalist countries and having an address in a capitalist country. In conclusion, the KGB and Czechoslovak Interior Ministry agree to regular, bilateral exchange of information on hostile residents of both countries who are thought to be in the employ of the special intelligence services of NATO countries and China.
