Central Asia has gained extraordinary importance in recent years in the framework of global energy security. China is the most significant example of a power that looks to its periphery as a viable option for energy supply. In Central Asia, Chinese companies are dynamic players having even broken the long Soviet and Russian monopoly over regional pipelines. This chapter examines the importance of the region within China's energy security, while not overlooking the potential contribution of the China-Pakistan economic corridor in the energy transit. In addition, Central Asia is likely to help China reduce the energy deficit in Xinjiang, through the import of hydroelectricity generated in Tajikistan and Kyrgyzstan. Although Central Asia's contribution to global energy security is low, it matters in a context of energy diversification, in which China's One Belt One Road brought a more promising dynamics to the cooperation between Beijing and Central Asian countries.
