On 22 June 1982, leaders of the three organizations formalised the formation of their coalition government by signing a Thai-sponsored agreement which established the Coalition Government of Democratic Kampuchea (CGDK). Accordingly, the CGDK's Inner Cabinet consisted of Sihanouk as the President of Democratic Kampuchea, Khieu Samphan as the Vice-President in charge of foreign affairs and Son Sann as Prime Minister. Below the Inner Cabinet were six separate committees responsible for national defence, economy and finance, social affairs and public health, military affairs and the media. During a meeting between Kim Il-sung and Sihanouk on 10 April 1986, in Pyongyang, Kim Il-Sung reassured Sihanouk that North Korea would continue to regard him as the legitimate head of state of Kampuchea. By 1987, Democratic Kampuchea still held its membership at the UN General Assembly, even though it lacked four criteria of statehood: people, territory, government, and supreme authority within the borders of a country. In spite of those limitations, forces of the three armed factions within the CGDK continued to fight the Vietnamese to achieve their objective of "bring about the implementation of the International Conference on Cambodia and other relevant UN General Assembly resolutions".
