Transparency International has actively supported the UNCAC from the early days, beginning with the Vienna negotiations in 2001-2003, and participated in the 2003 signing conference in Merida. Transparency International has emphasised all along that a follow-up monitoring system would be needed to ensure effective implementation of the UNCAC by governments, and played a leading role in the six-year effort that resulted in the adoption of the Review Mechanism at the Third Conference of States Parties (COSP) in Doha in 2009. Transparency International and its national chapters (NCs) have closely followed the UNCAC review process since it started operating in 2010 and prepared overview reports on the first three years of reviews.
