China's African policy from The Economist.
This article outlines China's methods in Africa, which involve buying influence with a complete disregard for human rights throughout the continent. This is to gain votes in the UN, to isolate Taiwan, and to gain access to raw materials to drive economic growth. The Chinese government stirs up support at home by reminding its citizens frequently of the wrongs inflicted by the West in the 19th century along with Japan's more recent incursions. The relationship between China and the US is quite complex, as the Chinese leadership probably has many grandchildren living in the US.
While many Americans believe a foreign policy should be altruistic first, it is important to remember that there are powerful entities outside of the US who don't see things that way.
