In many cases, an impartial third party can be more effective. If we look at peace negotiations as an analogy and look at, for example, those between FARC guerillas and the Colombian government they began in Oslo, Norway,(1) not in Colombia or any other South American country. This happens as in order for a conflict to be mediated, you need to have a neutral third party which no party can influence and has no preference. The same can be equally true of peacekeepers.  Due to African membership, the AU is unlikely to be considered impartial putting troops between them African factions. Of course, those African countries are part of the UN too, but due to the sheer number of countries in the UN, it is clear that the influence is much more diminished.
