Such a buffer could lower the chances of an accidental north-south clash. But its implementation depends on the two sides reaching an agreement over the demarcation of the border, an issue that has long been contentious.
The deal could also be disrupted by other outstanding issues, such as the sharing of oil rights between north and south.
AU adviser Alex de Waal, who has facilitated negotiations on security issues between Sudan’s north and south regions, said the parties agreed on Monday during talks in Ethiopia’s capital to form a common, demilitarised zone stretching across the 2 100km north-south border. It’s not yet known when the zone will go into effect.
The zone will stretch 10km north and south from the 1956 border, the tentative line drawn when Sudan became independent from Britain, de Waal said.
De Waal told The Associated Press by phone from Addis Ababa that discussions over a third-party military monitoring body – a United Nations peacekeeping force, for instance – were still to come.
Philip Aguer, spokesperson for the south’s army, said the southern military will support the agreement “100%” if both sides can agree where the actual border is.
“To me that is a good agreement, but the issue now is where is the border,” he said.
North invaded Abyei
North and south Sudan fought two civil wars off and on over more than four decades before signing a 2005 peace deal. But the sides’ relations took a nosedive earlier this month when the northern Sudanese army invaded and seized the disputed border town of Abyei.
The military action came after months of building tensions between the two armies in Abyei, a fertile, oil-producing border zone which both the north and south claim.
It sent an estimated 80 000 residents of the area running for their lives, fleeing into villages and towns in the southern state of Warrap, which is now experiencing what Western diplomats and UN humanitarian officials have called a perfect storm of factors resulting in food, fuel, and shelter shortages.
De Waal said the agreement to establish a demilitarised border zone provides a model for solving the Abyei crisis. He called the deal a necessary step between the two parties that will allow the Sudanese government to take the necessary action to demilitarise Abyei.
Since the Sudanese Armed Forces invaded the town of Abyei on May 21 with tanks, heavy artillery and air cover, the UN Security Council and a host of Western nations have repeatedly condemned the act. President Obama’s special envoy to Sudan called it a disproportionate response to an attack by the southern army on a UN-escorted northern military convoy in the area on May 19.
The Security Council has called for the immediate and unconditional withdrawal of the northern army from Abyei, but the government of President Omar al-Bashir has not made any concessions.
On the evening of May 26, the northern army bombed and destroyed the strategic bridge across the Bahr el Arab, called the River Kiir by southerners, which forms the 1956 border in the area.
De Waal expressed optimism that the agreement will provide a basis for re-establishing co-operative relations between north and south at a time when a number of key issues related to the future of the two regions remain unresolved.
