There are long land border lines and many developable passes. Under the direction of total national development strategy of coastal and border opening, considering the advanced condition of location,the new spatial frontier trade pattern of 'multilevel and all-round position' has initially been formed.That is,to develop westwards market in Middle Asia,to enlarge southwards market in Pakistan and to open up northwards market in Mongolia.The great progress of border opening has been made in Xinjiang.At present, Xinjiang is catching the opportunity to adjust the industrial structure and regional allocation,enhance horizontal economic combination and cooperation,and strengthen the infrastructures construction.Therefore more solid material foundation ofborder opening will be formed for further enlarging.展开更多
