Ending Sudan's internal conflicts has been a top priority of the transition government in power since last year's ouster of longtime dictator Omar al-Bashir amid a popular pro-democracy uprising.
The peace talks were mediated by South Sudan whose leaders themselves battled Khartoum as rebels for decades before achieving independence in 2011.
Sudan's government and rebel leaders gathered Saturday to drumming, singing and dancing as they prepare to sign a landmark peace deal aimed at ending decades of war in which hundreds of thousands died.
Minister and leaders of government from neighbouring countries as well as Egypt, Qatar and Saudi Arabia are expected to attend the ceremony in Juba, the capital of neighbouring South Sudan.
