“[China carries out] almost three times as many as the rest of the world put together, according to the most conservative estimate by Amnesty International. In 2008, the group confirmed 1,718 executions through news reports and public documents, but many others are not reported. Some analysts say the figure may be above 6,000. The exact number is a state secret.”
Many executions are done on the road using vehicles such as those designed by Jinguan Motors:
“Makers of the death vans say the vehicles and injections are a civilized alternative to the firing squad, ending the life of the condemned more quickly, clinically and safely. The switch from gunshots to injections is a sign that China “promotes human rights now,” says Kang Zhongwen, who designed the Jinguan Automobile death van in which “Devil” Zhang took his final ride.”
