Despite all the scaremongering, China’s motives for investing in Africa are actually quite pure. To satisfy China’s population and prevent a crisis of legitimacy for their rule, leaders in Beijing need to keep economic growth rates high and continue to bring hundreds of millions of people out of poverty. And to do so, China needs arable land, oil and minerals. Pursuing imperial or colonial ambitions with masses of impoverished people at home would be wholly irrational and out of sync with China’s current strategic thinking.
Moreover, the evidence does not support a claim that Africans themselves feel exploited. To the contrary, China’s role is broadly welcomed across the continent. A 2007 Pew Research Center survey of 10 sub-Saharan African countries found that Africans overwhelmingly viewed Chinese economic growth as beneficial. In virtually all countries surveyed, China’s involvement was viewed in a much more positive light than America’s; in Senegal, 86 percent said China’s role in their country helped make things better, compared with 56 percent who felt that way about America’s role. In Kenya, 91 percent of respondents said they believed China’s influence was positive, versus only 74 percent for the United States.
And the charge that Chinese companies prefer to ship Chinese employees (and even prisoners) to work in Africa rather than hire local African workers flies in the face of employment data. In countries like my own, Zambia, the ratio of African to Chinese workers has exceeded 13:1 recently, and there is no evidence of Chinese prisoners working there.
And as for the other articles, which talk about human rights violations, I guess the prisoners would take working for China over being imprisoned in a prison.
And those ghost towns exist in China too. Its because the property is costly, and there is no one to buy it.
