Иенг Сари
Ieng Sary led a mass defection from the Khmer Rouge in 1996, with half of its remaining soldiers (about 4,000) switching to the government side and Ieng Sary becoming leader of Pailin Province. A conflict between the two main participants in the ruling coalition caused in 1997 Prince Rannaridh to seek support from some of the Khmer Rouge leaders while refusing to have any dealings with Pol Pot. This resulted in bloody factional fighting among the Khmer Rouge leaders, ultimately leading to Pol Pot's trial and imprisonment by the Khmer Rouge. Pol Pot died in April 1998. Khieu Samphan surrendered in December 1998. On 29 December 1998, leaders of the Khmer Rouge apologised for the 1970s genocide. By 1999, most members had surrendered or been captured. In December 1999, Ta Mok and the remaining leaders surrendered, and the Khmer Rouge effectively ceased to exist.
