Grace Mugabe and her G40 supporters had little concern for monetary policy, and neither the Chinese nor anyone else wanted to channel open-ended financial flows to such a country. The South Africans, meanwhile, wanted to slow the number of economic refugees, about 3m of whom have fled Zimbabwe for Johannesburg, Durban and Cape Town, all of which already suffer from rising unemployment. And so when the coup came, there was little reason for anyone to help the Mugabes cling on – even their oldest allies.
It is far from certain a coalition will be possible, but opposition leader Morgan Tsvangirai has flown back to Zimbabwe from Johannesburg and is reportedly ready to discuss possibilities. Tsvangirai knows that Mnangagwa has a ruthless past. He was an animating figure behind the brutal suppression of largely fictitious dissent in Matabeleland in the 1980s, when Zimbabwean soldiers trained by North Korea killed thousands of innocent citizens.
