民主柬埔寨
Although the flags of the People's Republic of Kampuchea, and later the flag of the State of Cambodia, became the official flags within Cambodia after the ousting of the Khmer Rouge government of Democratic Kampuchea, the flag of Democratic Kampuchea would still be used by the Coalition Government of Democratic Kampuchea and in the United Nations. As the PRK failed to gain widespread international recognition most states kept diplomatic ties with the Coalition Government of Democratic Kampuchea.
