In a unanimously adopted resolution on Friday, the Council also demanded that the two countries finalize the establishment of an administration for the area, as well as constitute a police service, in line with an agreement signed in June 2011.
The pact, signed in the Ethiopian capital, Addis Ababa, provides for temporary administrative arrangements for Abyei and the withdrawal of troops by both sides.
The Council also urged Sudan and South Sudan to make regular use of the Joint Oversight Committee to ensure steady progress on the implementation of the agreement.
The mission’s mandate includes overseeing the demilitarization of the area and maintaining security. The final status of Abyei, which straddles the border between the two countries, has yet to be determined – one of the outstanding issues of the Comprehensive Peace Agreement which helped to end the long-running civil war between Sudan and South Sudan.
