Darfur's rebel groups reach deal

This article about Darfur's rebel groups having been agreed on a common position and want "final" talks with Sudan's government in near future somewhat sounds hopeful.
The decision/agreement to send 26,000 UN and African Union peacekeepers to Darfur was made last week. However, I am wondering how those institution play authentical roles in ensuring peace in Darfur.
It is cheering to haer that the Darfur's rebel groups have agreed on a common position, with this they can maintain a united position for the good of all Darfuris. To improve upon the situation, all parties must adhere to the terms of any agreement that will be reached subsequently, if this done, there is a very high probability to maintain peace in Sudan's troubled region.
These talks need to be truly multilateral if there is to be any hope for peace in Darfur. Without the officials from both sides of the Darfur conflict present, any agreements made cannot be held legitimate by all parties. Although the UN has been successful in some crises such as Haiti (for the present time) the situation in Darfur is one that cannot be solved without pressure on China, a UN Security Council Permanent Member. The UN needs to exercise its soft power resources against Sudan.
