A Chinese expert spoke out on Saturday at a Geneva conference against a rumor claiming China secretly performs 100,000 organ transplants a year, equal to the whole world's total.

Professor Wang Haibo said at the 14th Congress of the International Society for Organ Donation and Procurement that the rumor is "insulting the intelligence of transplant and medical professionals".

"I believe not one organ donation and transplant professional with a lucid mind believes this ridiculous accusation," said Wang, director of China' Organ Transplant Response System.
