South Sudan Liberation Movement/Army or SSLM/A former rebels and the national government delegation began peace negotiations on Friday in Juba.
The talks started after the former rebels lead by General Johnson Olony accepted the presidential amnesty in July, Bakhita Radio reported.
SSLM/A spokesman Gordon Buay said they started discussing power sharing and security arrangements.
He said the negotiations are projected to last for two weeks.
Mr Buay is optimistic that the two parties will reach an amicable agreement and the integration of SSLM/A forces into the SPLA, organized forces and civil service will begin.
Government’s delegation secretary Bor Wutchok Bor said they received concerns of SSLM/A to study and next week they will respond.
He pointed out that their responds will be positive because they work in line with the presidential amnesty and to make the whole process successful.
SSLM/A rebelled against Juba in 2010 and were in the bush for the last four and a half years.
