I would say that this trend has occurred for a couple of reasons. There is a recognition that the United Nations can't do everything and is not necessarily best placed to do everything; that regional organizations have a depth of understanding of situations on the ground--the African Union in Africa, for one--that can be extraordinarily valuable and can complement what the United Nations organization brings to a given situation.
I think we're evolving to a more partnership kind of approach, whereby the UN seeks to work with the strengths of regional organizations. I think that is a good trend that we applaud and encourage, because you can draw on the strengths of both the global organization--the UN--and the regional expertise of a regional organization.
