Some Reasons far Developing East-West Economic Cooperation. Parallel to the trend of more flexible and increasingly standardized political relations between East and West, preoccupations of a social and economic nature are beginning to play a decisive role in economic cooperation between the two spheres, progressively overcoming political prejudices and existing obstacles. The author attempts to make a tabulation of the economic and social motivations which determine East-West cooperation, because, in the final analysis, since they are aimed at precise economic advantages, they are the ones that further the normalization of international economic relations. The more general goal of economic activity, including the exchange of goods, is the increase of labor productivity, which cannot be achieved either by the East or West in a condition of economic autarchy. Other structural or conjunctural objectives are linked with it: for the socialist countries, that of bringing to an end or reducing the deficit of the internal market, improving the quality of production, importing technology and managerial techniques, procuring credit, etc. For the capitalist countries there is: fuller utilization of idle production capacities, assuring the supply of energy and raw materials through long-term agreements and combating inflation by importing less expensive products, etc. According to the author, economic cooperation can be expected to become increasingly important if not decisive in the near and distant future.
