In opposition to the newly created state, a government-in-exile referred to as the Coalition Government of Democratic Kampuchea (CGDK) was formed in 1981 from three factions. This consisted of the Khmer Rouge, a royalist faction led by Sihanouk, and the Khmer People's National Liberation Front. Its credentials were recognised by the United Nations. The Khmer Rouge representative to the UN, Thiounn Prasith, was retained, but he had to work in consultation with representatives of the noncommunist Cambodian parties. The refusal of Vietnam to withdraw from Cambodia led to economic sanctions by the US and its allies.
