| In January, 1964, regardless of the objection of the whole west world, especially the U.S, the France government under General De Gaulle recognized the People's Republic of China under the cold war circumstances, which resulted in so great effect that the establishment of the diplomatic relation between China and France was considered as a "nuclear explosion in diplomacy". After 40 years, there are many books and articles involved in the relation of China and France at home and abroad, but the study that discusses the two countries' relation from the evolvement of the French policy to Indochina after the Second World War is rare. This article aims to emphasize the great importance of the French Indochina's policy to the establishment of the diplomatic relation between China and France by analyzing the interest conflicts among China. France and the U.S.It includes four parts. The first chapter introduces the different policy of China, France and the U.S to Indochina in the early time after the Second World War. According to this chapter, America supported the French to govern Indochina again before the Geneva conference in 1954, but China supported strongly the resistance of the Indochina to France and the U.S. After the Geneva conference, America replaced the French status in Indochina, which made the contradiction between France and America become acute. Meanwhile, the conflict between China and France alleviated, which made it possible for the revival of the diplomatic relation between the two countries. The second chapter focuses on the contradiction between France and America before and after the Geneva conference, analyzing the causes of the contradiction. From the second chapter, we can know it is the contradiction between France and America in Indochina that drove France to antagonize America by uniting China. The third chapter expresses the center meaning that the strategic change of the French policy to Indochina made it recognize China. The conclusion generalizes the whole paper. |
