ソン・セン
In 1982 a formal political alliance, the Coalition Government of Democratic Kampuchea, was formed between the KPNLF, the FUNCINPEC royalists headed by Sihanouk and the remaining forces of the Khmer Rouge. After 1985 Sutsakhan was to meet with Son Sen of the Khmer Rouge and Prince Norodom Ranarridh, Sihanouk's son, who commanded FUNCINPEC's military arm, the Armée Nationale Sihanoukiste (ANS), to arrange military cooperation between the three movements.
