The purpose of this article is to analyse the process of Chinese economic expansion that is taking place in Africa and that mainly involves the energy sector, trying to understand the ways in which this expansion is taking place. The main objective is to investigate the relations between China and its main African partners, how these came about, and to deepen and analyse the agreements established. Secondly, the political and economic situation of each partner reported in the paper is analysed, assessing the impact China has had on the country by analysing the main economic indicators. Particular attention has been paid to understanding what is behind China's interest, whether it actually aims to help African countries or whether it intends to establish a relationship similar to previous European colonial relations..
