 On the eve of a state visit to the United States by President Hu Jintao, the 800-member British Transplantation Society also criticised China's use of death-row prisoners' organs in transplants, on the grounds that as it is impossible to verify that organs are indeed from prisoners who have given consent; the WMA once again condemned the practice on similar grounds.A BBC news report by Rupert Wingfield-Hayes in September 2006 showed negotiations with doctors in No 1 Central Hospital in Tianjin for a liver transplant.In February 2017, CGTN quoted former vice health minister Huang Jiefu as saying "From January 1, 2015, organ donation from voluntary civilian organ donors has become the only legitimate source of organ transplantations", and Francis Delmonico interpreting this as a ban on "the use of organs from executed prisoners" in January 2015.
