Critics of the Unification Church have accused the organization of being closely involved with covert CIA-authored operations against communism in Korea during the 1960s. The Church is known to have been involved with weapon and munitions manufacturing in Korea since the 1960s, as documented in a 1978 United States Congressional Report on the Unification Church. The explanation given by Korean Unification Church members is that all manufacturers seeking to do business in South Korea were required to supply the military.
