The rapid economic development of the developing countries and the increasing enhancement of South-South cooperation have contributed tremendously to a more plural and more balanced development of the global governance system. Meanwhile，to prolong the existing international power structure characterized by developed countries as the center and developing countries as the margin，the Western countries are striving to regroup themselves and formulate new international rules. The United States and France have speeded up their steps to return to Africa and their African policies manifest an outstanding feature of remilitarization. These new features and changes in the international politics as well as the adjustment of the African policies of some great powers have brought new opportunities and challenges for the future development of Sino-African relations.
