Abstract: The Sino-Kazakhstan International Cooperation Demonstration Zone is a strategic node of the north passage in the Silk Road Economic Belt. During its construction,it is important to accelerate the construction of cross-border railway,highway,aviation,oil and gas pipelines. This kind of interconnection strategy passage can not only enhance the economic and trade exchanges between Central Asia and North East Asia,but also strengthen China's new geopolitical pattern of all-round open to the eastern and western countries. Consequently,this paper firstly introduced the construction situation on the strategic passages of cross-border interconnection for the Sino-Kazakhstan International Cooperation Demonstration Zone. Secondly,the main problems were analyzed,i e.,a highly efficient integrated transport system has not been established,the structure of transportation modes is irrational,the cohension among different transportation modes is not tight enough,and the connection between the node cities and towns in its direct hinterland is very weak. Thirdly,the construction plans and emphases on the strategic passages of cross-border interconnection for the Sino-Kazakhstan International Cooperative Demonstration Zone were put forward based on the above analyses and problems:(1) based on the construction of Karamay-Tacheng-Astana Railway,the international railway passage from Timbuktu Port east to the Pacific and west to the Atlantic should be opened as a matter of priority;(2) Kazakhstan should construct another expressway to Western Europe and Western China(named ‘Two-West Expressway’),and Tacheng Region should create a comprehensive highway transportation patern as "one circle-two horizontals-three verticals" to connect the second Two-West Expressway;(3) Tacheng air corridor construction project should be implemented,and the construction of Urgal airport and Ayaguz airport in Kazakhstan should be actively promote,so as to strengthen the air access for the Sino-Kazakhstan International Cooperation Demonstration Zone;(4) the construction of crude oil and natural gas pipelines from Tyumen oilfield in Central Russia to Eastern Kazakhstan,Timbuktu Port,Karamay and other cities in Mid-Eastern China should be actively planned and promoted,so as to guarantee China's energy supply security. Finally,the guarantee measures and policy suggestions were put forward for the construction on the strategic passages of cross-border interconnection. The above perspctives and suggestions might greatly promote the construction of the Sino-Kazakhstan International Cooperation Demonstration Zone and the Silk-road Economic Belt.
