The African Union urged the presidents of Sudan and South Sudan, who will meet here Sunday, to strike a deal on the issues they still have to settle following the independence of South Sudan in July 2011.

Outgoing Commission chief "Jean Ping, looks forward to the summit between President Omar al-Bashir of Sudan and President Salva Kiir of South Sudan. He would like to encourage both presidents... to reach agreement on the outstanding issues in the post-secession relations between their two countries," the AU said.
