While it is the responsibility of member states to ensure that sanctions adopted by the United Nations Security Council are implemented, the council plays an equally important role in facilitating and promoting effective implementation. This paper discusses the role of the Security Council with a view to providing guidance for those involved in the council’s work, making the case for greater transparency. It briefly reviews current council practices and procedures relating to the Democratic People’s Republic of Korea (DPRK) and Iran sanctions regimes, including the working methods of the 1718 and 1737 Committees, and it identifies possible options for the council aimed at enhancing sanctions implementation through transparency-related measures.
