Czechoslovak foreign trade is of special interest for several reasons: First, Czechoslovakia is the East European country most active in trade in terms of per capita exports and imports of goods and, with a few exceptions (for instance, Bulgaria), also in terms of the ratio of visible trade to national product. In 1965 exports per inhabitant amounted to $189, compared with $181 in East Germany, $150 in Hungary, $144 in Bulgaria, $71 in Poland, $58 in Rumania, and $35 in the USSR. In the same year per capita imports were $188 in Czechoslovakia, $151 in Hungary, $ 149 in East Germany, $144 in Bulgaria, and $35 in the USSR. As in other Communist countries (with the exception of Yugoslavia), the ratio of foreign trade to national product is difficult to determine, mainly because of the almost complete divorce between domestic and foreign trade prices. One can only very roughly estimate that in 1966 Czechoslovakia’s ratio of visible exports to gross national product, in terms of approximative factor cost, was one fifth and the ratio of imports to GNP only slightly less than one fifth. Thus, Czechoslovak economy is again as dependent on foreign trade as it was in 1937.
