The presidents of Sudan and South Sudan are set to sign agreements aimed at preventing another war, though some major issues remain unresolved.

Officials say the deal, to be signed Thursday in Ethiopia's capital, calls for forces on both sides to pull back 10 kilometers from the disputed border.

The Sudan Vision newspaper quotes an official (Sudanese ambassador Abdul Rahman Sir Al Khatim) as saying the sides also reached deals on security and oil issues.

The two countries remain divided over who controls the oil-producing Abyei region and other border areas.

A VOA reporter in Addis Ababa says the signing ceremony was delayed Thursday but that Presidents Omar al-Bashir of Sudan and Salva Kiir of South Sudan are expected to sign as planned.

The north and south fought a 21-year civil war that eventually led to the south's independence in July 2011.

Lingering issues pushed the countries to the brink of war earlier this year. Sudan has accused the South of arming rebels in two of its states, while South Sudan accuses the north of launching air attacks.

South Sudan cut off oil exports through northern pipelines in January over a disagreement on transit fees. The lack of oil revenues has threatened the fragile economies of both nations.

The United Nations has threatened both countries with sanctions if they do not settle their issues.
