The China Africa Project has a nice summary of recent setbacks in Chinese engagement in Africa.
First, the Zambian government finally closed down the outrageously abusive Collum Coal Mine (this is the privately run mine where at least two Chinese managers have been murdered by their workers, and several Chinese managers have blasted protesting workers with bird shot. A really bad situation).
Also in the discussion: Botswana president Ian Khama complains about the quality of Chinese construction in a major power plant.
A hat tip to Henry Hall.
