Why Do Members of the Chinese Government Persecute Falun Gong?

Here are the three reasons for the unwarranted persecution of Falun Gong provided by most analysts and China specialists:

The popularity of the practice: Falun Gong practitioners outnumbered the Chinese Communist Party

Falun Gong was first introduced to the public on May 13, 1992. By the end of 1998, by the Chinese government's own estimate, there were 70 - 100 million people in China who had taken up the practice. Falun Gong had become "the largest voluntary organization in China, larger even than the Communist party." (U.S. News and World Report February 1999 issue)

Party officials scapegoat Falun Gong to gain politically

As economic and technological developments have become top priorities for China as a nation, many government officials, who specialize in political propaganda and ideological battles, will engender political unrest to provide them with a "cause" to gain political power. Falun Gong was made a scapegoat for this purpose. The propaganda was released through government-run media to defame Falun Gong and its founder from June 1996, and escalated to the mobilization of police and the use of physical violence in Tianjin on April 23, 1999. The development and escalation of the Falun Gong persecution actually happened over a period of three or four years.

Totalitarian Paranoia: Suspicious that there might be a hidden "mastermind" behind Falun Gong, Chinese President begins persecution to demonstrate political muscle

On April 25 1999, over ten thousand Falun Gong practitioners held a peaceful gathering at the Chinese State Council Appeal Office to appeal to the Central Government for the release of the citizens arbitrarily detained by police in Tianjin over the previous two days. China's Premier Zhu Rongji personally came out to meet with practitioners and the situation was resolved peacefully. Despite this, Chinese President Jiang Zemin authored and circulated documents to other government officials stating his belief that some political rival or "mastermind" within the Communist Party's top leaders was behind Falun Gong.

Consequently, Jiang equated his ability to "eradicate Falun Gong" with his ability to remain in power, and initiated the persecution.
