This paper is to review that the motivation of Doi Moi implemented by Communist Party of Vietnam is Ho Chi Minh Thought. Analysing the background and specific character of Ho Chi Minh Thought, I carefully look into the linkage of Ho Chi Minh Thought taken place in the process of Doi Moi. Generally speaking, the economic growth of a country seems to be affected by the leadership which conducts the state affairs. The same applies to Vietnam, where the sustainable economic growth after the economic reform and the open door policy in 1986 is lasted. According to economic experts there are a few conditions they are very optimistic in economic growth of Vietnam. First of all Vietnam has the big potential consumption market, the growing manufacturing industry, and the increasing foreign trade. Ho Chi Minh Thought, Communist Party ideology of Vietnam and the value of constitutional law, has contributed to this economic growth of Vietnam. Ho Chi Minh Thought is the concentration of oriental culture, Ho chi Minh's philosophy and nationalism, and the way of thinking of liberalism affected by France Revolution, reflecting the realities of Vietnam in the process of implementation of Vietnam revolution from capitalism to socialism based on Marx-Leninism. The focus to be emphasized in Ho Chi Minh Thought was pragmatism and nationalism. The fact that Communist Party of Vietnam leads its economic growth with the above mentioned ideologies is that it fully understands they took up the broad realm in the development of the state. Nationalism is what is an ideology which makes a race, a nation, and national identity the basic unit of the social formation. So whenever national interests emerge, nationalism appears as an ideology of a national community. And pragmatism is what is an ideology which makes social usefulness the standard of value in the human life and behaviour. In reality Vietnam has adhered closely to the flexible policy in terms of national interests. Traditionally The Communist Party of Vietnam has ruled over the people of Vietnam on the base of Ho Chi Minh Thought which can be a very considerable variable in not only economic policy, but other areas. Therefore Ho Chi Minh Thought has been the motivation of Doi Moi being under way.
