“Speak Softly and Carry a Big Stick”

Abstract

While sanctions and mediation are often used to address the same conflict situations, they are usually employed without significant coordination. Focusing on a rare case of a mediator successfully wielding the threat of sanctions, this article explores the utility of sanctions for mediation in the Yemeni political transition during the mandate of UN special adviser Jamal Benomar. Although the transition ultimately derailed, the analysis shows that the threat of sanctions can be used in different phases of the mediation process to provide mediators with the leverage needed to convince conflict parties to engage in negotiations, break stalemates during talks, nudge parties toward an agreement, or persuade potential spoilers to refrain from undermining the implementation of the negotiated agreement. Their success, however, not only depends on the degree of convergence between the application of the two instruments, but also on the type of target, regional support, and institutional backing.
