While Vietnam proposed to withdraw from Cambodia in return for a political settlement that would exclude the Khmer Rouge from power, the rebel coalition government as well as ASEAN, China and the United States, insisted that such a condition was unacceptable. Nevertheless, Vietnam declared in 1985 that it would complete the withdrawal of its forces from Cambodia by 1990 and it did so in 1989, having allowed the Cambodian People's Party government that it had installed there to consolidate its rule and gain sufficient military strength.
