It's not just Africa. China has mines in Africa, but it also has a very large presence in Latin America, in the southern cone. It is especially present in Chile and Peru, which are the largest copper producers in the world. The majority of their exports go to China. They also export to North America, but the raw product is mostly sent to China, where it is refined. China has mines around the world, but they're concentrated in Africa and South America.
