The G20 have committed to the implementation of international legislative frameworks, the adoption of measures in preventing and combating corruption, the strengthening of international co-operation, and a stronger engagement with the private sector. The OECD actively supports this work.



The G20 Anti-Corruption Working Group asked the OECD to prepare a study on the impact of corruption on economic growth as part of the Russian Presidency's focus on growth. This Issues Paper, presented to Leaders in St Petersburg, investigates the relationship between corruption --  and anticorruption measures -- and economic performance. By analysing the channels through which corruption affects economic performance, this Paper offers a better understanding of the complex factors hampering the economic potential of countries affected by corruption.


Whistleblower protection has been identified by the G20 as an essential tool to encourage the reporting of misconduct, fraud and corruption. The OECD elaborated a complete study on G20 whistleblowers protection frameworks (pdf), as well as a related compendium of best practices and guiding principles for legislation, which was supported by the G20 AWG in the First Monitoring Report that Leaders adopted in Cannes, November 2011.


The G20 relies on the OECD’s expertise in public sector integrity, including through its Integrity Reviews, to support its agenda on integrity of public officials through financial disclosure and on integrity in public procurement. The OECD, together with the World Bank, presented several concept notes which led to the adoption by the G20 of High-Level Principles on Financial Disclosure.


Engagement with the private sector in the fight against corruption has been a key prioriy of the G20 since the Seoul Summit.

The OECD organised jointly with the Russian Presidency and with the support of the UNODC, the third High Level Conference on Anti-corruption at the OECD on 25-26 April 2013, building on the outcomes of the two previous High-Level Anti-corruption Conferences in Paris 2011 and Puerto Vallarta 2012. The conference brought together high-level government, business and civil society representatives to examine best practices for combating corruption, with a particular focus on: Promoting transparency and integrity in organising sport and other major events and on Cutting-edge measures for governments and business to combat corruption.

The OECD has a close relationship with the B20 Task Force on Anti-corruption and has regularly provided contribution to its work. Under the Russian presidency, it participated in three work streams of the B20 Task Force, including the one on public procurement, on collective action which launched a Collective Action Hub, and on the legal framework.



The OECD has actively supported G20 countries in implementing their commitment on foreign bribery under the Seoul and 2013-2014 Action Plans. The Organisation is engaged with the G20 countries that are not Parties to the OECD Anti-Bribery Convention (China, India, Indonesia, and Saudi Arabia), including through the organisation of technical seminars and high-level events on foreign bribery.

China, India and Indonesia have been attending the meetings of the OECD WGB on a regular basis as ad hoc participants.  Building on the OECD’s expertise and countries’ experience in the monitoring of the Convention, and at the request of the G20, the OECD prepared guiding principles on solicitation and on enforcement of foreign bribery rules.  

Moreover, effective and efficient Mutual Legal Assistance (MLA) is essential in the investigation and prosecution of transnational corruption cases, and the recovery of assets derived from such criminal conduct. The G20 asked the OECD and UNODC to report on the High-Level Principles on Mutual Legal Assistance (pdf) for the St Petersburg Summit.
