China has become a major trading and investment partner of Sub-Saharan African economies since the early-2000s, with the economic impact of China’s relationship with Sub-Saharan Africa having become the subject of an increasing literature. The paper shows the complexity of these trade and investment relationships and their impact on Sub-Saharan economies. It argues that beyond their ambivalent effects, these relationships may foster the structural transformation of African economies, i.e. a break with the pre-existing structure of the economy, industrialisation and productivity growth. Sub-Saharan African economies have indeed exhibited spectacular growth rates since the early-2000s, which have mainly been driven by China, via several direct and indirect transmission channels, notably China’s demand for goods produced in Sub-Saharan Africa and its contribution to high international commodity prices (e.g., for metals, oil), Sub-Saharan export structures being characterised by a high proportion of primary commodities. Different views could suggest that there are uncertainties, in particular that Sub-Saharan growth rates stem from distorted export structures, i.e., based on primary commodities with low value-added, and that these growth rates may not imply any change of commodity-based export structures. These growth rates may even strengthen commodity-dependence, as high growth rates and high prices are incentives to continue the status quo and may lock African economies into the exporting of primary commodities, with its negative effects (vulnerability to volatile prices and external shocks, ‘Dutch disease’). These processes may threaten Sub-Saharan African economies’ prospects for industrialisation and they may be compounded by the weakening of African industrial sectors by cheaper manufactured products from China and its undervalued currency. China’s export credits may also expose African economies to future debt problems. Similarly, Afri
