ヘン・サムリン
Many members of the Kampuchean People's Revolutionary Party were former Khmer Rouge members who had fled to Vietnam after witnessing the wholesale destruction of Cambodian society as a result of the regime's radical agrarian socialist and xenophobic policies. Several prominent KPRP members, including Heng Samrin and Hun Sen, were Khmer Rouge cadres near the Cambodian-Vietnamese border who participated in the Vietnamese invasion that toppled the Khmer Rouge.
