薬殺刑
China commonly employs two methods of execution. Since 1949, the most common method has been execution by firing squad, which has been largely superseded by lethal injection, using the same three-drug cocktail pioneered by the United States, introduced in 1996. Execution vans are unique to China, however. Lethal injection is more commonly used for "economic crimes", such as corruption, while firing squads are used for more common crimes like murder. In 2010, Chinese authorities moved to have lethal injection become the dominant form of execution; in some provinces and municipalities, it is now the only legal form of capital punishment. The Dui Hua foundation notes that it is impossible to ascertain whether these guidelines are closely followed, as the method of execution is rarely specified in published reports.
