Twenty-eight years after the fall of the Khmer Rouge in Cambodia, many Cambodians are still unclear about what really took place during the 1975-1979 regime, during which an estimated 1.7 million people died. Cambodia still suffers economically, socially and psychologically from the legacy of the Khmer Rouge and the years of war before and since. This has also impacted on the next generation of young Cambodians, who are reportedly poorly informed and sceptical about the Khmer Rouge. This research explores the root causes of the apparent disinterest and lack of knowledge among Cambodia’s youth. It also examines the potential role that radio can play in supporting and contextualising survivors’ testimonies and educating young people about their recent history. This is achieved by studying a phone-in radio series entitled Ka Pit (The Truth), which aims to educate young people about the Khmer Rouge regime.
