Son Sen - Chief of Staff of Khmer Rouge Forces

Chief of Staff of Khmer Rouge Forces

After the Cambodian coup of 1970, and the subsequent establishment of the Khmer Republic under Lon Nol, Sihanouk was to join with his former Communist enemies in forming the GRUNK, a Beijing-based government-in-exile. The Khmer Rouge's forces were soon to be swelled by thousands of new recruits, attracted in part by Sihanouk's name. Son Sen, whilst not a prominent member of the GRUNK, had considerable power thanks to his high position in the government's forces on the ground – CPNLAF, the Cambodian People's National Liberation Armed Forces. Along with Ieng Sary, he was responsible for the North-Eastern Zone, the stronghold of the Party 'Centre'.

By 1972 Son Sen had become Chief of Staff of the Khmer Rouge forces. Despite occasional criticisms – his colleagues found his style peremptory and his point of view "bourgeois", and he was openly criticised by Hou Yuon at the Party's 1971 Congress – his devotion to Saloth Sar and his closeness to the Party 'Centre' guaranteed his senior position.
