After more than three decades since the demise of the so-called genocidal Khmer Rouge regime, in which an estimated 1.7 million people died, in 1979 in Cambodia, real justice for victims of the massacre still remains elusive even though the Khmer Rouge tribunal, which was established in 2006, has been in the process of prosecuting the senior leaders and those most responsible. The talk will be mainly about how the Khmer Rouge tribunal, the court that must ensure that impunity does not exist, seeks justice for Cambodian victims. The genesis and process of wars and conflicts, particularly the mass killings in the second half of the 1970s in Cambodia, will be primarily highlighted in the talk.
