South Sudan had previously rejected an outside force, but the head of the Intergovernmental Authority on Development said that the government had accepted a protection force without preconditions.
Mahboub Maalim spoke to reporters after several regional heads of state met on the crisis. He also said the recently named First Vice President, Taban Deng Gai, had agreed to step down if opposition leader Riek Machar returns to South Sudan's capital, Juba.
Machar, who had been first vice president, fled the capital into hiding shortly after the fighting began last month. His rival, President Salva Kiir, replaced him with Taban.
