Imprisoned Falun Gong practitioners are particularly targeted for organ harvesting Falun Gong
In 2015, thousands of Falun Gong practitioners reportedly were arrested or sent to brainwashing centers or other detention facilities. Brainwashing centers are a form of extralegal detention known to involve acts of torture. Based on statements from Chinese health officials, the long-standing practice of harvesting organs from prisoners was to end on January 1, 2015. However, many human rights advocates believe the practice continues. Imprisoned Falun Gong practitioners are particularly targeted for organ harvesting. Li Chang, a former government official sentenced to prison for his involvement in a peaceful Falun Gong demonstration, is among the countless Falun Gong practitioners who remain imprisoned at the end of the reporting period. The Chinese government continued to deny Wang Zhiwen a passport or the ability to travel freely to receive proper medical care following the torture he endured during his 15 years in prison. Chinese authorities denied a visa and barred entry into mainland China to Anastasia Lin, a human rights advocate and Falun Gong practitioner. As Miss World Canada 2015, Ms. Lin was scheduled to participate in the Miss World event held in China in December 2015.
