The G20, through its Anticorruption Working Group established in 2010, is a leader in the global fight against corruption. The OECD has been actively engaged in assisting its efforts by supporting the development of tools to strengthen members’ legislative, regulatory and institutional frameworks to improve public sector integrity, fight foreign bribery, improve international co-operation and engage with the private sector.



The G20 Anti-Corruption Working Group asked the OECD to analyse the linkages between corruption and economic growth. Under the Russian Presidency, the OECD issued  a study on the impact of corruption on economic growth which analysed the channels through which corruption affects growth. Under the Australian Presidency, the OECD, with contributions from the World Bank, developed a report on the Consequences of corruption at the sector level and implications for economic growth and development which analyses the impact of a range of corrupt practices on economic growth and development in four key sectors: utilities and infrastructure, extractive industries, health and education. The report provided the basis of the G20 High-Level Principles on Fighting Corruption to Promote Strong, Sustainable And Balanced Growth.


Fighting global corruption requires effective measures to promote the integrity and transparency of the public sector. Strengthening financial disclosure frameworks for public officials and addressing the challenges in vulnerable sectors like public procurement are important priorities of the G20. The OECD actively supports the G20 efforts in this regard, including by assisting in the development of the  G20 High-Level Principles on Financial Disclosure. Under the Turkish Presidency, the OECD was instrumental in the drafting and adoption of G20 Guiding Principles on Integrity in Public Procurement. In 2016, the OECD welcomed the Turkish Presidency’s focus on Open Data which can significantly and directly reduce the cost of corruption. The Organisation contributed its long-standing work on analysing Open Government Data initiatives to the development of G20 Anti-Corruption Open Data Principles


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), including a compendium of best practices and guiding principles for legislation, which was supported by the G20 at the Summit in Cannes, November 2011.


Engagement with the private sector in the fight against corruption has been a key priority of the G20 since the Seoul Summit and is inscribed in the successive Action Plans.  To date, the OECD has co-organised five high-level conferences on anti-corruption. The most recent was held on 6 March 2015 in Istanbul, Turkey. The conferences bring together high-level government, business and civil society representatives to address cutting-edge challenges and discuss practices developed by all stakeholders to address them.  The three previous editions of the conference were held in Rome (2014), Paris (2011, 2013) and Puerto Vallarta 2012.

The OECD has a close relationship with the B20 Task Force on Anti-corruption and has regularly provided contributions to its work.



Eliminating bribery of foreign public officials remains a key priority of the G20 anticorruption agenda and all countries have committed to enact and implement foreign bribery legislation. The OECD has actively supported G20 countries in implementing their foreign bribery commitments under the successive Anticorruption Action Plans. The Organisation engages 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. Under the Australian and Turkish Presidencies, the OECD supported the G20 self-assessment exercise and drafted a progress report on that basis issued in 2015.

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 the Guiding Principles on Enforcement of Foreign Bribery Offence.  

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 OECD, together with the UNODC, developed  G20 High-Level Principles on Mutual Legal Assistance (pdf) for the St Petersburg Summit.
