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.

A bi-polar world emerged at the end of World War II. The United States and the Soviet Union were the world's superpowers and tensions between them spiraled consequently bringing about the Cold War. United States foreign policy during the Cold War revolved around containment policy. The Middle East during the Cold War was a region that the bi-polar world's superpowers wanted to influence, and protect. The United States during the Cold War warned the Soviet Union through presidential doctrines that it would fight to keep the Middle East from communism, and the Soviet Union's influence. The bi-polar international power structure did not allow the United States the ability to pick its battles. The power structure that constrained the Cold War forced the United States to react to the Soviet Union, and it forced foreign policy makers to always consider the Soviet Union's response to its policies. United States foreign policy in the Middle East during the Cold War threatened wit h military methods to solve local and regional instabilities. However, the United States was constrained by the bi-polar world thus, it was cautious of committing military troops in the region permanently and upsetting the region's delicate balance of power. United States foreign policy toward the Middle East has changed between 1981 and 2006. This change is in the direction of greater use of military methods to resolve what various administrations have perceived to be local and regional instability. This change in policy is partly attributable to changes in the United States power position in the world. A United States foreign policy shift in the Middle East occurred due to a change in the distribution of political power within the interstate system. This change has had the following result: the United States is no longer constrained by the bi-polar international power structure that characterized the Cold War period. The collapse of the Soviet Union created the uni-polar internationa l power structure. United States foreign policy is now capable of deploying the military to resolve local and regional instabilities in the Middle East, and that deployment has tended to become increasingly permanent in nature.
