Regional mediator Zuma met President Robert Mugabe and Prime Minister Morgan Tsvangirai in Harare on Wednesday and Thursday to solve problems that risk unravelling a power-sharing deal meant to rebuild Zimbabwe from economic ruin. Zimbabwe's unity pact helped stem the economy's decade-long free-fall but squabbling within the coalition over policy and the slow pace of reforms has held back progress and stood in the way of fresh elections. Zuma, appointed by regional grouping SADC to mediate in the crisis, said he was encouraged by the spirit of cooperation displayed by the country's leaders. "The parties have agreed to a package of measures to be implemented concurrently as per the decision of the SADC troika in Maputo," he said at a briefing, flanked by bitter adversaries Mugabe and Tsvangirai.
