The National Development and Reform Commission，Ministry of Foreign Affairs and Ministry of Commerce of the People’s Republic of China，with State Council authorization，jointly issued “Vision and Actions on Jointly Building Silk Road Economic Belt and 21st-Century Maritime Silk Road” in March 2015. The “Vision and Action” plan proposes that China will build six economic corridors with related countries. Among the six economic corridors，The New Eurasian，China- Central Asia-West Asia and China-Pakistan corridors are extending from Xinjiang. This paper argues that the future of the above three economic corridors is very cheerful，but still faced with many challenges，which mainly are security issues，cross-country coordination issues and the consultation and docking of technical standard issues. If these three issues can be solved，the three economic corridors will have a huge positive effect on the construction of “The Belt and Road”.
