You completely avoided the question about substitution yet again.If you think that I think that the chinese people are evil then you can't read.
Basically you have no alternative.
I can tell you exactly what the chinese are doing in africa. They want africa stable so they can extract resources at market prices (this is what separates east vs west). They also do not interfere with african politics (another thing that separates east vs west). They also want africa to be more educated so they can use africa as a manufacture continent the way america used them in the 70s. Eventually the Chinese will be moving away from manual labor and will need cheap goods for their emerging middle class.
I fail to see how this is a losing situation for Africa since this is exactly how China came onto the world stage. Care to explain?
