The Central Asia has been a particularly important position in China’s foreign strategy. The security situation in Central Asia is closely related to the national interests of china. From 2015 to the first half of 2016，under the influence of the complex and volatile political and economic situation of the world，the security situation in Central Asia has some new features and new trends. The 2015 presidential election in Kazakhstan and Tajikistan and the Kyrgyzstan and Uzbekistan parliamentary elections successfully held in Central Asia laid foundation to continuously maintain stability. As same as in other parts of the world，Central Asia also faces a serious threat of extremism and terrorism. At the same time，the situation in Afghanistan has come to deteriorating trend which caused some security pressure for these countries. Since the Central Asian countries taking appropriate and effective measures，the overall situation of security in Central Asian countries have been still under control and in a certain period of time could be maintained basically stable. For the impact of the situation in Afghanistan to Central Asia should have a cool analysis that we can neither be taken lightly nor should we exaggerate the danger，so as not to affect the overall cooperation between China and Central Asia.
