Due to historical，internal and external reasons，there are exactly many problems in Central Asia，such as terrorism，extremereligiousism，the struggle between domestic political forces，the complex economic situation and so on. The countries of Central Asia have achieved remarkable results in coping with these difficulties by consolidating political power and strong sectors，combating three evil forces，restricting non-governmental organizations’ activities，developing economies，pursuing a balanced and focused foreign policy. The Shanghai Cooperation Organization plays a very important role in safeguarding the security and stability of Eurasia. On the whole，it is difficult for the Central Asia region to undergo major unrest in the next period，and its security and stability situation can be expected.
