Regarding the 2011 referendums, the Council requested that UNMIS be prepared to play a lead role in international efforts to provide assistance to support preparations for the referendums, including an advisory role related to security arrangements. The Secretary-General had expressed concern that there was a lack of progress in preparations for the referendums.[5] UNMIS would also be required to implement the north-south border demarcation concerning the disputed town of Abyei, the resolution of conflicts in Southern Kordofan and Blue Nile states, the creation of referenda and consultation commissions and wealth sharing. There was concern about restrictions placed on the activities of UNMIS in certain areas, and in this respect all parties were urged to co-operate with UNMIS and allow it freedom of movement.
