Khieu Samphan
So, in February 1982, Sihanouk met with Khieu Samphan in Beijing to work out their differences. In what he described as "another concession", Khieu Samphan proposed forming a coalition government without integrating the other resistance groups into institutions associated with Democratic Kampuchea. However, he emphasized that all parties must defend the legal status of Democratic Kampuchea as the legitimate state representing Kampuchea on the world stage. In May 1982, with the urging of Sihanouk, Son Sann decided to form a coalition government with the Khmer Rouge.
