South African President Kgalema Motlanthe and his Mozambican counterpart Armando Geubuza arrived in Zimbabwe on Monday morning to try and salvage a power-sharing deal signed by Zimbabwe's three major political parties last year.
Former South African leader and SADC appointed facilitator to the talks, Thabo Mbeki also jetted in the morning for the resumption of talks.
The Southern African Development Community (SADC) executive secretary Tomaz Salamao arrived in Zimbabwe on Sunday.
The deal, which has Zimbabwean President Mugabe retaining his post, opposition MDC leader Morgan Tsvangirai becoming prime minister and Arthur Mutambara as deputy prime minister, is seen as the most practical way of getting Zimbabwe out of its decade-long crisis.
Signed on September 15 last year, the deal has not yet been implemented as the parties wrangled over the control of key ministerial, ambassadorial and governorship posts, among others.
Several meetings had been called to break the impasse, with Monday's being the latest one as the SADC continues to have hope of convincing the parties to work together and form an all inclusive government.
