As bribery and corruption increasingly involve international trade and investment, nations have started to fight corruption in cross-border commerce. Led principally by the Organization of Economic Cooperation and Development (OECD), major trading nations have combined efforts to combat corruption by criminalizing bribery of a foreign public official. Korea has ratified the OECD's Bribery Convention and enacted its own Foreign Bribery Prevention Act (FBPA). The paper describes Korea's implementation of the OECD Convention, analyzes the effect of the OECD Bribery Convention on Korean Criminal Codes and analyzes how the FBPA and Korean Criminal Codes differ in their purposes and in some of their elements, suggesting that differences between the two laws may eventually need to be reconciled. It also presents the increased multilateral efforts to fight corruption. In particular, it describes how awareness of the various harmful effects of corruption generated the multilateral momentum to fight bribery and corruption and focuses on the OECD Bribery Convention's various instruments to fight transnational bribery.
