2 Compendium: High Level Review of United Nations Sanctions and more effective in advancing Security Council objectives. The rationale, nature, and scope of sanctions should be clearly and widely communicated, and regular engagement with UN membership and stakeholders prioritised. Training on sanctions implementation should be provided to the stakeholders, including regional organizations and private sector groups to promote greater awareness and compliance with sanctions. Promote UN integration and coordination Institutional coordination within the UN leaves room for improvement. Sanctions should be integrated with other UN responses (e.g. peacekeeping and political missions), including between the field and headquarters, and the field and expert groups. Regular briefings, training, and the sharing of expertise and information among UN entities can promote cooperation and greater consistency across sanctions regimes. A new sanctions technical committee should be established to manage interagency coordination; review and monitor sanctions implementation and compliance; develop guidance, best practices, and proposals to improve implementation; standardise committee practices; facilitate cross-cutting and thematic discussions of sanctions issues; and consider expert group recommendations across regimes. Strengthen sanctions infrastructure Improved procedures for recruiting, appointing and supporting (administratively and substantively) expert groups and the Ombudsperson, reflective of their specialised and independent roles, are necessary. To promote effective monitoring of sanctions implementation and compliance, expert groups should enhance evidentiary and investigative methodologies, by benefiting from clusters of subject-area expertise to operating procedures currently in use by other investigative bodies, peer review, and stronger collaborative investigations, and be provided adequate resources, training, and support. An induction and training programme for committee chairs and missions would contribute to improved effectiveness of sanction committees. Engage relevant international institutions, instruments, and actors A broad range of institutions and mechanisms, not part of the UN sanctions system (e.g. entities addressing arms control/non-proliferation/export controls, financial controls/commodities, transport/border controls, judicial processes) but with relevant expertise and information, represent opportunities for cooperation on sanctions implementation. A mapping exercise should
