This paper calculates and analyzes the export trade interests of Kazakhstan’s five major export products from 2006 to 2014 by building the index of export income share based on export income index. It concludes the export trade interests of Kazakhstan’s minerals has been increasing and it creates generous profits. However, in recent years, Kazakhstan's export structure has been adjusting. It increases the export of raw materials processing products and constantly improves the export trade interests. By comparison, it is found that the Kazakhstan's access to export interests is limited and its economic structure and policy is the most important reason. So when China promotes the trade cooperation with Kazakhstan, it is of great necessity to strengthen the policy communication, change the philosophy of cooperation and further expand the fields of cooperation in addition to energy and resources. And what's more, China would develop cooperation in agriculture, agricultural products processing, infrastructure, machinery manufacturing, clean energy, finance, transportation, business services, and social services and so on.
