Discriminatory
In China, the death penalty targets poor and marginalized groups including ethnic minorities, migrant communities, political dissidents, and so called "separatists". Since the “war on terrorism” began, Muslims in the Xinjiang Uighur Autonomous Region have been the target of intense crackdowns, and political dissidents may be labeled as 'terrorists' and sentenced to death, regardless of whether they have used or advocated violence, and regardless of whether they have been implicated in any crime.
Organ Trafficking
Amnesty International is very concerned about reports of the sale of organs harvested from executed prisoners without permission. While officials deny the practice, accusations have been made that prisoners are given blood thinners, and executed in a manner to preserve the organs, which are reportedly harvested right away and taken directly to hospitals. These reports are very disturbing, and would constitute very serious human rights violations.
