Exploring the impact of United Nations peacekeeping operations on the external affairs of host states.

Studies of United Nations (UN) peacekeeping operations (PKOs) typically give scant attention to an important aspect of host states' development: their external affairs. This article identifies ways in which UN PKOs can shape the external affairs of host states, focusing on UN peacekeeping in the post-Cold War period. We present the findings of a quantitative content analysis of key UN peacekeeping documents to establish which aspects of host state external affairs have been of concern to the UN. We then provide a conceptual framework that maps three areas of external affairs in which PKOs are particularly influential: relationship-building; institution- and diplomatic capacity-building; and the shaping of policy in domains of external affairs. We identify three pathways through which PKOs shape the external affairs of host states: mandated roles, improvised actions, and unintended consequences. Drawing on documentary analysis and original interview data, we illustrate our conceptual framework through an exploration of the impact of peacekeeping on the external affairs of two countries that have hosted large-scale UN-led peacekeeping missions in recent decades: Timor-Leste (East Timor) and Liberia.
