This paper briefly discusses the essence of the US-China competition in Africa and introduces a principial categorization to group their respective interests in Africa. It is about what US and China individually want or seek to achieve in Africa, through their own tools and policies towards the continent. For that, we thought, understanding these elements and dimensions will enable the students of International Relations in general and of great power politics, in particular, to better elucidate the post-cold war international system dynamics especially, in the developing world. The principial categorization, through the case of the DRC, helps understand why the US-China competition is overall moderate.
