The world economic outlook is subject to an increasing number of uncertainties and risks. Patterns of world trade，international labor division and global resource allocation are undergoing profound changes，in a context of parallel development of economic globalization and regionalization. The status of both China and African countries in the world has been changed and still continues to evolve. China-Africa economic relations are facing new opportunities as well as more challenges. In the next seven years，a symmetrically interdependent structure is increasingly reflected in China-Africa economic relations. New common interests of the two sides and areas of cooperation will be based on their respective goals of transformation and development. In the changing circumstances of the world economy，efforts should be made in terms of improvements of cooperation mechanism and framework，management system of overseas investment，overall planning of Sino-African cooperation and soft power to promote the sustainable development of China-Africa economic relations.
