Established in 1994, the OECD Working Group on Bribery in International Business Transactions (Working Group) is responsible for monitoring the implementation and enforcement of the OECD Anti-Bribery Convention, the 2009 Recommendation on Further Combating Bribery of Foreign Bribery in International Business Transactions (2009 Anti-Bribery Recommendation) and related instruments. This peer-review monitoring system is conducted in successive phases and is considered by Transparency International to be the ‘gold standard’ of monitoring.

Made up of representatives from the States Parties to the Convention, the Working Group meets four times per year in Paris and publishes all of its country monitoring reports online.
