“Sudan and South Sudan on Saturday failed to agree on how to withdraw armies from their disputed border after a round of talks in Ethiopia, delaying again the resumption of crucial oil exports.
The African neighbours came close to war in April in the worst border clashes since South Sudan seceded from Sudan in 2011 under a 2005 deal which ended decades of civil war.
After mediation from the African Union, both countries agreed in September to set up a demilitarized buffer zone and resume oil exports from landlocked South Sudan through Sudan. Oil is vital to both economies.
But neither side withdrew its army from the 2,000-km (1,200-mile) border due to mistrust left from one of Africa’s longest civil wars.
