I have already reported about the necessity of international cooperation, our role and measures under the present conditions of private technological exchange in the Japanese and Korean Consulting Engineers Meeting at Taejeon, Korea. Continuously I have been discussing whether we, Japanese & Korean consulting engineers can give technological cooperation and support with the regard to industrial technological development, enhancement of industrial infrastructure, social and economic development. I am focusing on Vietnam which has been in the course of economic development to excess in a sense and this country attracts the world's attention. I probe the possibility of technological cooperation under the cooperation of Japanese & Korean consulting engineers while I introduce the present conditions of Vietnam. In addition Vietnam has become a member of ASEAN officially, and the foreign investment in Vietnam has gotten on the right track. Moreover, the regularization of lawsystem in Vietnam is well under way and they aim at joining advanced nations in the 21st century.
