The aim of this handbook is to provide the 57 OSCE participating States and 11 Partners for Co-operation with a reference guide on available legal tools, the latest legislative and policy trends, and pertinent measures and practices to prevent and suppress corruption. The Handbook should raise awareness of the range of international instruments available to national policymakers and anti-corruption practitioners, and assist them in developing and implementing effective anti-corruption policies and measures, thereby reducing the possibilities for corruption, instability and transnational crime.
