China's Double-Edged Economic Sword

Since in the US it is still Africa Day and the UN is using the day to promote awareness of Africa and it's economic growth, I thought this video from CNN International is rather fitting.

In short, this makes me think of China's economic involvement in almost every African nations, a much bigger impact than many European countries and the US at the moment. During one of my interviews for my upcoming documentary on the Korean perceptions of Africa, Africans and African-Americans, one person stated, while watching an episode of Current TV's Vanguard titled "Chinatown, Africa," that China's involvement is making Africa better. This video questions the price. If South Africans are at risk of losing their jobs (and they live in Africa's strongest economy), doesn't that widen the gap between the rich and the poor and lead to future economic problems?

Already, many African countries are faced with this extreme gap between the wealthy and the impoverished and are working to close it. Could China's "it's strictly business" policy in Africa further expand this gap? Or is it really helping?
