After the ending of the Cold War and the break down of the Soviet Union, the old polarized system collapsed and the new international structure of world powers hasn't formed yet in a short time. Researchers of international relations have diversely defined the new framework of world power as ¡§uni-polar¡¨¡B ¡§ multi-polar¡¨ or ¡§multi-powers under uni- polar¡¨. From the perspectives of China, the definition of ¡§ multi-powers under uni- polar¡¨ can most properly describe the new international system and is completely in accordance with the international strategy of China. In the assumption, uni-polar means US and multi-powers means other important powers, including major regional actors or groups like China､Russia､Japan､EU and some newly developing powers like India､Brazil and South Africa. In response to the huge change of international system and in order to develop much more power of influence on international affairs,China introduced the concept of ¡§New Security perspective¡¨ to try to develop common interests with major powers and neighboring states through cooperation and dialogues. Then in 2003, China publicly proposed the concept of ¡§Peaceful Rise¡¨ and soon has been regarded as competitive opponent by U.S.A and countries around China. The way China rose aroused the attention of the international society and ¡§China Threat Theory¡¨ has become more and more well-known. The purpose of this research is to explore the theoretical basis､strategic value and purposes of the theory about China's peaceful rise, and extensively to analyze how China develops new international strategies and comprehensive national power. Additionally, I try to develop findings about the theme and hope that will helpful for our government to scheme corresponding policies to ensure our national security.
