Abstract
Aid from socialist nations to Vietnam during the war is one of the outstanding issues in the history of the Vietnam War (1954–1975). North Korea is also a country with a very high spirit of aid to Vietnam. In this article, the authors use two main historical research methods (the historical method and the logical method). In order to complete this article, the authors gathered a variety of sources, including records from Vietnam’s national archives, the Wilson Center Digital Archive (USA), and some research findings relating to the study topic conducted by other authors. Thereby, the article will focus on clarifying the following three issues: North Korea’s attitude regarding Vietnam’s resistance war against the US; North Korea’s aid activities to Vietnam between 1965 and 1973, and assessments of North Korea’s aid activities to Vietnam between 1965 and 1973. The research findings of the article will provide new material to help elucidate international support for Vietnam’s resistance war against the United States’ invasion. In addition, it will help to overcome the document limitations that exist in the current investigation of diplomatic actions between North Korea and Vietnam. It will also serve as a significant document for anyone interested in the Vietnam War.
