The importance of Central Asia for China increased with the change in international power structure, growth of its economy, rapid industrialization and increase in population. China is regarded as the second largest energy consumer in the world while Central Asia has rich energy resources and raw materials complementary for its economic growth. It is interested in the energy resources of Central Asia for the security of its energy supply and a large market for its finished goods. Prior to Central Asian energy resources, China was importing oil from the Middle East. The route of oil supply from M.E to China was passing through Malacca strait, under the control of United States, a perceived rival of China in the world politics. In case of conflict this route may be blocked by United States. This situation worried the Chinese policy makers and prepared a comprehensive policy regarding the energy resources of Central Asian region. Energy is not the only concern of China in Central Asia; it is also worried about the security of its Xinjiang, sharing border with some Central Asian Republics (CARs). About 60% of the population of Xinjiang are Uyghur Muslims. The same ethnic community also exists on the other side of the border in the Central Asian Republics. China has an apprehension that in case of instability in the region, terrorists organizations may instigate the China9apos9s Uyghur for independence. That is why, China is supporting United States in its fight against terrorism. Politically, it wants to reduce the influence of United States in the region by integration with the CARs (Central Asian Republics) through SCO particularly after US military penetration in the region in 2001. Applying a descriptive-analytical approach in the paper, the interests of China in CARs are surveyed.
