The South African president, Jacob Zuma, says he has agreed to a package of measures with key figures in Zimbabwe's power-sharing government that he hopes will end the political deadlock there.
Mr Zuma said he was encouraged by his visit and further negotiations will be held in coming weeks.
A spokesperson for Zimbabwe prime minister Morgan Tsvangirai says his party is pleased with the outcome so far but there has been no official reaction yet from President Robert Mugabe's ZANU-PF party.
Meanwhile, Mr Zuma has survived a vote of no-confidence back home. The vote follows an admission by Mr Zuma, who has three wives, that he has a child out of wedlock.
