Since the 1940s Vietnam has become an area of war events, up to the 1970s. Japan, France, the United States of America and China have been directly involved in these conflicts, but indirectly, however, the Soviet Union. War conflicts have always been complemented by the level of national struggle and the conflict of internal forces within Vietnamese society itself. The attention is focused on clarification of peace negotiations and on the influence of internal Vietnamese situation and international relations on their course.
