In recent years, there has been a continous attempt to describe changes in the possibilities for international action in relation to conflict situations. How does the coordination and management of international involvement in post-conflict situations contribute to a lasting peace? The article examines the principle texts associated with peace implementation in the former Yugoslavia, and extracts from these some of the elements of the coordination of multilateral activities. The article places this analysis in the context of past and current research on the question of the coordination of multilateral institutional activities as a first step in the grounded study of the organization and management of international involvement in securing peace in post-conflict situations.
