In the introduction the author underlines the importance and role of the foreign trade in the socialist economy. The rate of increase in the trade with abroad in CMEA countries ought to undergo a considerable acceleration and surpass the rate of increase of the national income and industrial production. In the course of the last years the socialist countries have done and still do big efforts aiming at extension and deepening of the profits of economical relations with highly developed West European countries. These efforts were expressed in active cooperation in bilateral talks that were to lead to liberalization of export to CMEA and EFTA countries, to the membership of GATT reacted by some of the socialist countries and in finished negotiations under the name of Kennedy Round. In that way we theoretically reached the approach to western markets — that in general depends on the quality of exported goods, their attractive price, short terms of delivery and profitable sale conditions for foreign contractive parties — this fact however does not solve the problem. Liberalization of import to CMEA and EFTA countries secures the approach to the west markets only in formal and legal terms. But there exists still another aspect of the problem. These markets got under control of the state and international concerns. The introduction of a new competitor is very difficult in that situation. A solution could be found in creating such a situation in which our presence on the West markets would be not only a competition but simultaneously a form of cooperation, profitable for our partners. Cooperation in the international scale would be the required form. Further on, the author discussed in the article three forms of cooperation: licence agreements in the branch of building and exporting machines, gadgets and agreements for cooperation with West enterprises in the aim of supplying on the markets of the third world. The author dealt as well with forms of scientific and technical cooperation and discussed profits of cooperation for both sides. Finishing the article the author put forward the thesis that cooperation helps to enliven the economical relations between East and West. Of course only under the condition that it will be only economical form of international cooperation with no political strings.
