These affiliated agencies were divided into two categories: intergovernmental economic organizations (which worked on a higher level in the member countries and generally dealt with a wider range of managerial and coordinative activities) and international economic organizations (which worked closer to the operational level of research, production, or trade). A few examples of the former are the International Bank for Economic Cooperation (managed the transferable ruble system), the International Investment Bank (in charge of financing joint projects), and Intermetall (encouraged cooperation in ferrous metallurgy).
