China has promised, yet again, to no longer use the organs of executed prisoners for transplants, beginning next month. The country has made the promise in the past, but high demand and chronic shortages have meant the government has continued to turn to death-row inmates for organs. According to human-rights groups, the government has done this without the prisoners’ consent, or that of their families. Only 0.6 out of every million people in China donate organs. In Spain, for example, 37 out of every million do.
