David Matas and David Kilgour have released an updated version of their 2007 book Bloody Harvest, which presents new evidence that Falun Gong practitioners in China are being killed for their organs. Falun Gong is a set of exercises with a spiritual foundation begun in 1992. It was initially encouraged by the government of China, but was banned in 1999. Matas is an international human rights lawyer based in Winnipeg. Kilgour is a former long-time member of parliament from Edmonton and former Minister of State for Asia and the Pacific.
