the two year probationary period. Article 49 in the Chinese criminal code explicitly forbids the death penalty for offenders who are under the age of 18 at the time of the crime. The SPC also issued a policy in 2007 which required lower courts to arrange for the visitation of condemned criminals by relatives; forbade the practice by local authorities of parading prisoners on death row; and required that executions be publicly announced. However, capital punishment in China can be politically or socially influenced. In 2003, a local court sentenced the leader of a triad society to a death sentence with two years of probation. However, the public opinion was that the sentence was too light. Under public pressure, the Supreme People's Court took the case and retried the leader, resulting in a death sentence which was carried out immediately. Since 1980, the state's security apparatus has initiated various "strike hard" () campaigns against specific types of crime. Critics have noted that the campaigns lead to the streamlining of capital cases, where cases are investigated, appeals heard, and sentences carried out at rates much more rapidly than normal. Since 2006, Chinese Supreme Court justice Xiao Yang has worked to blunt the "strike hard" policy with his own policy of "balancing leniency and severity" (), which is supposedly influenced by Hu Jintao's harmonious society concept. Xiao's policy includes improving the quality of appeals by mandating that the SPC, rather than simply the high people's court, review capital crime cases; increasing use of the "death sentence with two years' probation"; and requiring "clear facts" and "abundant evidence" for capital cases. The abolition of the death penalty in Hong Kong since 1993 is a major reason why China does not have a rendition agreement with that city. , a proposed extradition bill has sparked massive protests. The list of capital crimes includes counter-revolutionary crimes, such as organizing an "armed mass rebellion"; endangerment of public security, such as committing arson; and crimes against the person, such as the rape of a person under the age of 14. During the 1980s, "economic crimes" such as bribery, drug trafficking, and embezzlement were added to the legal code. Capital punishment in China can be imposed on crimes against national symbols and treasures, such as theft of cultural relics and (before 1997) the killing of giant pandas. Executions under the pretense of political crimes are extremely rare and
