A substantial part of this study investigates the development of Czecho-Slovak foreign trade relationships in the period after the crash of the totalitarian regime in 1989. The author agrees with the new liberal foreign economic policy of the CSFR, even though it means an unusually complicated climate and conditions for the re-orientation of foreign trade to the highly developed industrial countries. Kosta doesn't think, that the theoretical conception of foreign trade relations transformation is 'shocked'', he emphasizes that, in practise, gradualistic patternalistic access is exercised. Special attention is paid to the inflow of foreign capital (mainly direct foreign investments) to the CSFR as an ''imperativ of transformation''. With regard to the big share of German capital in CSFR, the author suggests a nonsensicality of a danger of ''colonization'' of our country by German investors. According to him, the way out could be more active access to the other foreign partners. At the end, Kosta evaluates the results of development of the trade balance and the balance of payments in the CSFR after 1989 in interaction with development of the national economy. Even though foreign trade isn't a factor of growth yet, the author recommends for this aim, a policy of opening the economy to the world without excessive state protectionism.
