ヘン・サムリン
Despite the help of the Vietnamese Army, as well as of Soviet, Cuban and Vietnamese advisers, Heng Samrin had only limited success in establishing the PRK regime in the face of the ongoing civil war. Security in some rural areas was tenuous, and major transportation routes were subject to interdiction by sporadic attacks. The presence of Vietnamese throughout the country and their intrusion into Cambodian life added fuel to the traditional Cambodian anti-Vietnamese sentiment.
