The OECD-GVH Regional Centre for Competition (“RCC”) has successfully hosted the first virtual seminar of 2021 on “Tackling Bid Rigging in Public Procurement” between 2-4 of March 2021. During this three-day seminar, expert competition officials illustrated enforcement and advocacy actions conducted in their jurisdictions against bid rigging. Participants had the chance to expand their knowledge on practical tools and tips for an effective investigation, including the OECD Guidelines for Fighting Bid Rigging in Public Procurement through the careful examination of best practices. They also gained new perspectives on how to improve cooperation between competition authorities and public procurement bodies. The online seminar thoroughly piqued the interest of the participants and reached an audience of 104 participants from 22 countries. The RCC would like to express its gratitude to the speakers and participants for the successful organization of the event.
