Swaziland’s King Mswati, Mozambican President Armando Guebuza and Zambian President Rupiah Banda will hold talks hoping to help narrow differences between Zimbabwe’s leaders. 

Zimbabwe’s unity government, which was formed in February, plunged into a new crisis last month after the premier Tsvangirai partially pulled out the inclusive government over the implementation of their power-sharing agreement.

The stalemate in Harare comes after months of bickering over the unity deal.

Tsvangirai’s office said it hoped that the Mozambique talks would yield positive results that would be acceptable by all parties. "The troika will meet in Mozambique in a bid to break the current deadlock," Tsvangirai’s spokesman James Maridadi said.

According to Tsvangirai, if the three-leader summit fail to yield results, he would press for a full summit of the 15-member Southern African Development Community (SADC).

It was not yet clear by Tuesday whether both Tsvangirai and President Mugabe would attend the Maputo meeting.

The stand-off is the biggest crisis to hit Zimbabwe’s new government, which has managed to stabilise an economy ravaged by hyperinflation, but is still severely strained by political disputes.

Mugabe is accusing by the premier of undermining the coalition but Tsvangirai says Mugabe is a "dishonest and unreliable partner".

DRC, leader who is currently in Harare met Mugabe on Monday with Mugabe saying he expected Kabila to tell Tsvangirai that he must re-join the coalition "and must be able to face the problems and not to run away from them."

Kabila the SADC’s current chairman, arrived in Zimbabwe on Sunday to meet the country’s feuding leaders.
