Several Weiquan lawyers, including Teng Biao, Jiang Tianyong, and Li Fangping, offered legal aid to Tibetans in the wake of the March 2008 Tibetan protests. The protests resulted in the imprisonment of at least 670 Tibetans, and the execution of at least four individuals. Chinese government sources asserted that the unrest and violence in Tibet had been masterminded by the Dalai Lama and executed by his followers for the purpose of fomenting unrest and disrupting the 2008 Summer Olympics in Beijing. The Open Constitution Initiative (OCI), operated by several Weiquan lawyers and intellectuals, issued a paper in May 2009 challenging the official narrative, and suggesting that the protests were instead a response to economic inequities, Han Chinese migration, and religious sentiments. The OCI recommended that Chinese authorities better respect and protect the rights and interests of the Tibetan people, including religious freedom, and pursue the reduction of economic inequality and official corruption.
