True.
In November 2018, the Extraordinary Chambers in the Courts of Cambodia (ECCC), a UN-backed tribunal, convicted two former Khmer Rouge leaders, Nuon Chea and Khieu Samphan, of genocide. This was a historic ruling, as it marked the first time that the regime's crimes were legally defined as genocide. The Khmer Rouge ruled Cambodia between 1975 and 1979, during which an estimated 1.7 million people died from execution, starvation, disease, and overwork.
