Landlocked South Sudan shut down oil production in January after failing to agree with Sudan on how much it should pay to export its oil through northern pipelines.

"It's an agreement about all of the matters. The issues that were outstanding were charges for transportation, for processing, transit," former South African President and AU mediator Thabo Mbeki told reporters.

He gave no details, and there was no immediate comment from Sudan and South Sudan which have been negotiating to end hostilities at the AU in Addis Ababa.
