JUBA - South Sudan said on Wednesday it is seeking international arbitration to settle a dispute with neighboring Sudan over ownership of several contested borderlands.
The African neighbors, which split apart in July, have clashed repeatedly along their 1,800 km (1,200 miles) long border, parts of which passes close to oilfields.
The two edged close to resuming full-blown war in April when South Sudan's army seized the Heglig oil region, before withdrawing in the face of international pressure.
The African Union (AU) has managed to bring back both sides to the negotiation table but talks broke off last week over disputes over the positing of their boundary line.
South Sudan's chief negotiator Pagan Amum said international arbitration was the best way to determine the status of the disputed border areas.
