Zimbabwean President Robert Mugabe insisted today that his country is not a failed state and accused the US of being fragile because of its economic dependence on China. <br/><br/>Mugabe pointed to Zimbabwe's 90-per cent literacy rate to support his claim that the southern African country, which has battled economic chaos in recent years, is one of the best resourced on the continent. <br/><br/>He said this during a panel discussion at the World Economic Forum on Africa in Durban.
