Created in 2000, Dui Hua’s Political Prisoner Database (PPDB) contains information about political and religious prisoners incarcerated in China since 1980. Using mostly open-source materials, Dui Hua collects information on non-violent:

  • Political dissidents: people imprisoned for expressing their opposition to one-party rule by exercising universally recognized rights to free speech and association and often charged with “endangering state security” crimes such as “subversion” and “incitement”
  • Religious practitioners: people persecuted for holding religious beliefs that are not officially sanctioned, including members of house churches and Falun Gong
  • Ethnic minorities: people labeled “splittists” and jailed for participating in cultural and pro-independence movements
  • Petitioners: people jailed for seeking redress to grievances related to land seizure, demolition, corruption, miscarriages of justice, and other issues

The purpose of the PPDB is to advance clemency and better treatment for at-risk detainees by analyzing trends in the persecution of individuals who exercise their universal human rights to free speech, association, and expression; documenting the treatment of political and religious prisoners in the criminal justice system; providing raw material for the drafting of prisoner lists of concern; and informing dialogue with government officials inside and outside China.
