Abstract：When the West is experiencing a relative decline， China is now the second largest economy in the world. Facing the great changes of international relations and the relationship between China and the rest of the world， China diplomacy has a great number of transition opportunities and challenges . Having exercised survival-centered revolution diplomacy and development-centered diplomacy， China is carrying out great-power diplomacy to bring about a great rejuvenation of the Chinese nation. The exercise of great-power diplomacy with Chinese characteristics should be consistent with prevailing international relations and Chinas national conditions. Great power diplomacy with Chinese characteristics should focus on peaceful development and promote a harmonious world instead of Chauvinism and power politics.
