There will be some change in the heavy imbalance of the world's forces and new development in the multipolarization of the
world's patterns in the early 21st century. American economy is no longer in a dominant position and the economy growth of each major force is relatively balanced. The EU and Japan tend to seek more dependence and Russian nationalism is on the rise. There also increase some strong external foreign policies and active subordinate forces. Therefor, the principal contradiction in the early 21st century
international relations is still between the singlepolar and the multipolar. Their interaction plays a leading role in the world's political development of the early 21st century. Each major force is going to wage an all - round struggle for building the structure of the 21st century international orders. In our external security
environment there are more uncertain factors than before, such as the escalation, the armament race and the increasing turbulence in the geo - strategic strategic area. The US has clearly strengthened its containment over China and some neighbouring countries are also trying to restrict China by drawing support of the superpowers. Religious foundamentalism, national splittism and international terrorism, which spread over Central - Asia, constitute a threat to Northwest China's security and stability.
