The United Nations post-conflict presence must help to develop national strategies targeting such key priorities as the promotion of women's rights, youth employment, the protection of vulnerable social groups, the establishment of the rule of law and the strengthening of State institutions. It is vital in that vast undertaking that the United Nations efforts be effectively coordinated so as to mesh the establishment of peace, peacekeeping, peacebuilding and development in a coherent manner. The Peacebuilding Commission has a key role to play in that context.
