This book evaluates UN performance in ensuring good governance in Cambodia and Timor-Leste from a human-centred standpoint. East Asian perspectives are juxtaposed with universal aspirations, and the legality, legitimacy, and effectiveness of UN operations in the two countries are considered. Each of the case-studies assesses the justifiability of intervening and of actions and policies implemented during the intervention, as well as considers the justifiability of the conditions left after UN withdrawal, while also including specific policy recommendations.
