The
multipolarization tendency of the world political pattern has been characterized by its protacted nature,complexity and
unstability since the Post Cold War,and now it is beginning to assume new characteristics after the kosovo War. Firstly, it is encountering america's attempt to construct a single polarized world, Secondly it is restricted by Russia and China's Frailty as two of the world polarizations. Thirdly, it is still weak and feeble. The above mentioned characteristics will have great impact on china's peripheral security and particularly, America's pursuing the global strategy of single polarized worldwill menace extremely and directly china's security. Therefore, a new type of security concepy must be established, a mew type of synthetical
security strategy must be formulated and a mew type of strategic principle must be carried out so as to maintain China's security ad well ad the peace and stabilty in asia Pacific Region and the whole world, and eventually accerlerate the formation of the
multipolarization pattern in the world.
