Like in practically every other continent, China has made itself a force to reckon with in Africa. I have thus had a very long string of posts [1, 2, 3, 4, 5, 6, 7, 8] examining its role and the views other have of China investing there. These range from the helpful and benign ("South-South cooperation") to the exploitative and malign ("the yellow man's burden"). While I still very much recommend Jian Ye-Wang's IMF research paper "What Drives China's Growing Role in Africa?" for those looking for a more comprehensive review, our friends at the World Policy Journal have a handy single-page geographic review depicting where and how much China is investing in various African nations.
Here's hoping you find it informative!
