What contributed to the consensus to establish an implementation and compliance mechanism during the negotiations of the 2013 Minamata Convention on Mercury? This outcome was inextricably linked to consensus on establishing a financial mechanism that was satisfactory to both developed and developing country parties. However, given the complex interlinkages between these issues, the history of discussions of compliance in closely related multilateral environmental agreements, and the wide range of interests and preferences among parties to the negotiations, the path to consensus was not clear until late in the negotiating process. While the compatibility between the proposed mechanism and States' interests was crucial to the outcome, the role of individuals in crafting the treaty text and facilitating negotiations was also essential. Thus, a complete analysis of the path to that agreement must consider the role of individual leaders in strategically guiding delegates to identify the points at which their interests converged.
