Corruption is not a problem confined to one country, and since its harms transcend national borders, the international community has been working together to solve this problem for decades. The international community's anti-corruption discussion and cooperation began with the enactment of the Foreign Corrupt Practices Act (FCPA) in the United States in 1977, through the enactment of the Organization for Economic Cooperation and Development's (OECD) Anti-Bribery Convention in 1999, and the conclusion of the UN Anti-Corruption Convention in 2003. The G20 Summit, a global economic consultative body that emerged in the wake of the 2008 global economic crisis, recognized corruption as the main cause of the global financial crisis, and the 2010 G20 Seoul Declaration emphasized cooperation on corruption at the international level. The <Anti-Corruption Action Plan> was adopted in the form of an annex. This action plan includes contents to urge member countries to join and ratify major international conventions against corruption, such as the United Nations Anti-Corruption Convention and the OECD Anti-Bribery Convention, as well as a cooperative system to prevent corrupt public officials from using the financial system and to prevent corrupt public officials from entering and providing shelter. Measures that require close cooperation between countries, such as Goryeo and support for the recovery of hidden assets overseas, were included. In addition, each member country agreed to report the situation every year so that the <Anti-Corruption Action Plan> could lead to effective policies. In order to lead and actively participate in these changes in the international situation, it is judged that Korea, a member of the G20, needs basic research for active implementation and policy and institutional reorganization based on this.
 This paper examined the contents of international activities centered on the UN Anti-Corruption Convention to respond to corruption, the foundation of the domestic legal system and the current status of domestic legal implementation of international agreements. In addition, institutional and policy directions to be improved for future anti-corruption activities were presented.
