The MOFAT Diamond Scandal was exposed around early January 2012, in which the ambassador of South Korea's Ministry of Foreign Affairs and Trade, Kim Eun-seok, leaked information on his illegal purchase of stocks of a mining firm called CNK International by falsifying information of a diamond reserve in Cameroon. This incident generated criticisms against the Lee Myung-bak government. The scope of the investigation later spread to other senior South Korean public officials.
