Falun Gong in China. Wikipedia says : " It differs from other qigong schools in its absence of fees or formal membership, lack of daily rituals of worship, its greater emphasis on morality, and the theological nature of its teachings. Although the practice initially enjoyed considerable support from Chinese officialdom, by the mid- to late-1990s, the Communist Party and public security organizations increasingly viewed Falun Gong as a potential threat due to its size, independence from the state, and spiritual teachings. By 1999, some estimates placed the number of Falun Gong adherents in the tens of millions. Tensions culminated in April 1999, when over 10,000 Falun Gong practitioners gathered peacefully near the central government compound in Beijing to request legal recognition and freedom from state interference. This demonstration is widely seen as catalyzing the suppression that followed.
On 20 July 1999, the Communist Party leadership initiated a nationwide crackdown and multifaceted propaganda campaign intended to eradicate the practice. Former Canadian Secretary of State David Kilgour and human rights lawyer David Matas were asked by the Coalition to Investigate the Persecution of Falun Gong. In July 2006, they published "Report into Allegations of Organ Harvesting of Falun Gong Practitioners in China", which concluded that large numbers of Falun Gong practitioners were victims of systematic organ harvesting throughout China."
