This article is to see what Vietnam's response towards territorial dispute in the South China Sea is. A foreign policy of Individual countries is generally affected by various factors. Vietnam as a socialist country maintains one-party dictatorship in which the whole power is concentrated on the Communist Party of Vietnam. Thus CPV' volition can become a very important variable, which can have a decisive influence upon the direction of foreign policy. Above all CPV is in the position of the only leading-organ for the people in Vietnam. President Ho Chi Minh was the founder of the Communist Party and the State of Vietnam. Ho Chi Minh himself took the portfolio of foreign affairs of Democratic Republic of Vietnam during 1945-1946 when the country's revolution was in its first days of success, dealing with both internal and external enemies. The country was in an extremely dangerous and chaotic situation. Vietnamese diplomacy of the Ho chi Minh era was the most significant turning point in Vietnam's diplomatic history. Vietnam's foreign policy was based on Ho Chi Minh's nationalism. He was born in French colonial era and searched for the path for national liberation. He also struggled for the national independence and reunification of his country. In this process he of his own accord became a nationalist. To find out the way of the national independence he combined communism with nationalism due to the need of the outside assistance. He emphasized that for the national interests to be achieved one should gain the support from the major power. So far the CPV regards Marxism-Leninism and Ho Chi Minh Thought as its ideological foundation and compass for action, which means that Vietnamese diplomatic policy is still carried out according to Ho Chi Minh's nationalism. According to the basis of Ho Chi Minh Thought Vietnam is looking for the outside assistance to cope with China for the territory dispute in the South China Sea. Lately America expressed a strong intention of intervention in the dispute for its national interests. Eventually, there is a good chance of confrontation between America and China in the conflict of the South China Sea.
