Sanctions listings and delistings can alter the conditions under which negotiations take place. They can serve as warnings and incentives, stigmatize (or rehabilitate) stakeholders in negotiation processes, inhibit (or facilitate) logistics such as travel, and attempt to stabilize peace settlements. Despite the many ways in which sanctions listings and delistings can affect mediation processes, relatively little is known about the general listing and delisting patterns employed by the UN Security Council or their interactions with autonomous measures. However, an understanding of the listing and delisting of individuals is crucial to the strategic application of sanctions, and particularly their potential use by mediators. This report, therefore, aims to inform UN and other mediators, providing them with a better understanding of the broader listing and delisting dynamics of the UN and interrelations with autonomous sanctions by other authorities. In so doing, the report provides data previously unavailable or difficult to access and of potential interest to practitioners and analysts. It concludes with a set of considerations for mediators who may contemplate delistings as a tool in mediation processes.
