In August 1981, unity talks between the three organizations appeared to have collapsed as a result of conflicting interests. Sihanouk, who feared the resurgence of the Khmer Rouge, proposed that all resistance groups disarm themselves following the withdrawal of Vietnamese troops from Kampuchea. Meanwhile, Son Sann demanded that the KPNLF be the lead organization within the proposed alliance, and the leaders of the Khmer Rouge "most compromised" by the atrocities in Kampuchea be exiled to China. Against these preconditions, Khieu Samphan reminded his rivals that the autonomy of the Khmer Rouge and Democratic Kampuchea should not be undermined. On 22 November 1982, Singapore, with the backing of ASEAN, proposed that three organizations form a coalition government with equal decision-making powers within the alliance. Singapore's proposal was welcomed by Sihanouk, who believed it was a fair deal for the non-communist movements. Khieu Samphan, on the other hand, rejected that idea, viewing it as an attempt by Sihanouk and Son Sann to isolate the Khmer Rouge. However, Sihanouk knew that Chinese support would not be made available to the FUNCINPEC unless he made some compromises and joined the Khmer Rouge on their terms. 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.
