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.
