South African President Jacob Zuma says Zimbabwean leaders have agreed on a roadmap towards an end to the Zimbabwe's crisis.

South African leader, who is on a state visit to Zimbabwe, has acted as a regional mediator under a Southern African Development Community (SADC) mandate to settle differences between Zimbabwe leaders and to uphold a power-sharing deal meant to sustain he country's much-needed unity.

Zuma has already met with President Robert Mugabe, Prime Minister Morgan Tsvangirai and Opposition leader Arthur Mutambara in Harare.

He has made an attempt to solve the political parties' disputes stemming from rows over key government posts, foreign sanctions and other domestic problems amid an economic meltdown in the impoverished country.

"The parties have agreed to a package of measures to be implemented concurrently as per the decision of the SADC troika in Maputo," Zuma said at a briefing, referring to a November 2009 meeting between Zimbabwe's rival parties in Mozambique in order to resolve the political stand-off.

"I believe that the implementation of this package will take the process forward substantially," AFP quoted him as saying.

Meanwhile, Vincent Magwenya, spokesman for the South African leader, said that Zuma's separate talks with Mugabe and Tsvangirai on March 17 were "quite encouraging, in the sense that President Zuma got an impression that parties were as keen as we are to move things forward."

"There was commitment all round to work harder in finding a lasting solution," Magwenya noted.
