(4) Why CT is Growing CT in its many forms can be considered a response to the difficulties facing both industrial and developing countries. CT is vital for centrally planned Eastern European countries as a means of overcoming the uncertainty of domestic production plans and achieving the bilateral balancing of trade. It is also required by Eastern European countries as a means of stimulating Western technology transfers. Developing countries need countertrade in order to finance imports from each other instead of relying on the conventional imports-for-cash method. CT transactions are also required by developing countries as a means of enhancing their regional economic integration and their political solidarity. Industrial countries would prefer CT if the goods countertraded were more valuable to them than money. For all of these reasons, countertrade is growing and is expected to grow as long as the need for it exists by both parties. (5) Flows of Countertrade Goods CT transactions currently involve most of the countries of the world. However, to determine the directions or the flows of countertraded goods, it is important to start by determining the locations of the partner countries. Geographically, there are three groups of CT partner countries: North (which includes the 24 OECD member countries), East (which includes the Eastern European countries) and South (which includes all the developing countries). Using these geographic groups, we can distinguish the following flows of CT goods: a) The East/West direction, commonly called West/West, is the most important in trade relations between Western countries, including the United States and Canada, and Eastern European countries and other centrally planned economies. The OECD has estimated the value of Western exports to Eastern European countries through CT transactions at US$ 35 billion during the period between 1969 and 1979. The most common forms of CT include the transfer of technology and know-how and the sale of machinery and equipment for natural resources. One of the most important examples of a CT 65
