My thesis paper mainly focuses on the China cultural diplomacy and its soft power policy. China¡¦s economic reforms have transformed the international status. China is raising power recently. However China suffered the question about the political validity and the doubt of China threat, in order to keep maintaining a peaceful international environment, China has learned to use soft issues to serve its national interests. Cultural soft power is the best choice for China in such situation. According to Joseph Nye¡¦s idea, soft power is attracting force derived mainly from intangible resources such as national culture, political values, and its foreign policies. This thesis discovered that Beijing although wants to remold the civilized great nation image, it has to deal with the domestic belief crisis. Even, China on the one hand must construct the opening national image; on the other hand still continue to suppress the domestic Internet opinion. The Chinese Communist Party which cultivates the soft power is the destroyer. China ignores that the cultural diplomacy intrinsic essence is to sell the truth. China packs the national image with the cultural soft power without thinking of the national prestige. Although China repeatedly emphasizes the harmonious peace, the international society is still filled with anxiety about the China's power.
