This article examines how major powers conceive the role of the United Nations (UN) in peacebuilding. We conceptualize the UN's role along the distinction between conflict management and conflict resolution and distinguish between the types of tasks and the approach the UN can adopt. We map states' conceptions of the UN's role in peacebuilding by coding peace-related speeches at the UN Security Council (1991-2020) delivered by China, France, Russia, the United Kingdom, the United States as well as Brazil, South Africa, and Turkey as rising regional powers. Our findings show that states' conceptions differ regarding the type of tasks the UN should do. However, the main fault line between the countries lie in the approach the UN should adopt to conduct peacebuilding tasks. We conclude that major powers see a role for the UN beyond mere conflict management as long as it is done with respect for national sovereignty.
