Abstract
Over the period from 1950 to 1975, regional cooperation increased dramatically in Asia. Expansion in the scope and capabilities of regional organization proceeded through the establishment of 24 IGOs primarily concerned with technical and economic problems. With institutions characteristically specific in function and making decisions through consensus and intergovernmentalism, the structure and growth in Asian organization may be described from the theoretical perspective of classic international functionalism. The more politicized IGOs have not been successful and politicization has been most influential in retarding organizational growth. The rate of growth in Asian organization increased only as politicization from East-West, North-South, and developmental and power differences among participants was avoided by limiting participation to compatible nations. A rising rate of growth in Asian organization was correlated with an increasing concentration of cooperative activity among nations in Southeast Asia compatible in policies on East-West and North-South issues and similar in power and level of development.
