Yes, China has established a good relationship with Africa by providing non-reimbursable assistance in such political interest dominant age. Although it totally betrayed the economic efficiency, it lays foundation of cooperations today. First, China aided Africa in infrastructure constructions, it is something like a basement in Africa, so they will need our product and services continuously. For example, road construction and expansion will need our raw meterials such as cement and other building materials. Now, China is even exporting TV serials to Africa...I am not sure, maybe India step in Africa later than China? So India's faster growth rate is understandable, because China's trade amount with Africa is very huge with a lower gowth.
But, I think trade number is just one side, I wish China can export more high technological product to Africa, such as vehicles, PCs and even satellite services.
