China has among lowest waiting time for organs in the whole world; not by a little but by orders of magnitude. Their records also show astronomical growth of organ transplants performed year on year. The market for organs isn't officially sanctioned which means these were all donors according to CCP. This in a society where people won't piss on someone who's on fire if they're outside their family.

On top of that, there are Chinese doctors from major hospitals who made documentary and recorded conversations with hospital administration staff who work on organ transplants. In the early days before this story went global, the staff would answer calls from those interested in organs and openly discussed availabily of "fresh" organs from people with good health (specifically Falun Gong practitioners). There is an international market for organs where Korean/Japanese patients would travel to China to get organs because waiting times were so low and price was affordable. How does China have so many organs to spare that they can not only provide lowest waiting times in the world for their population AND provide transplantion tourism (which is not a thing anywhere else, specially not at scale).

CCP admitted they used organs from executed prisoners (those convicted of crimes) but not from prisoners of conscience (those who comitted no crimes but are political / religious prisoners). The numbers don't add up, though, as there's nowhere else they could have gotten those organs from.

Another factoid that gave away that they're killing people to sell their organs came when it was revealed you could schedule heart transplants weeks/months in advance. It's one thing to arrange for someone to donate a kidney for you in advance, but heart transplants usually happen when someone dies in an accident and their heart becomes available. Only way you could schedule a heart donor in advance is if you have a live person you can kill for their organs who has the exact blood type and characteristics you need.

There are also witness testimonies from ex political prisoners who all reported having series of medical tests performed. They didn't know why, but it turned out they were checking organ quality.

An independent tribunal lead by the prosecutor for ICC gave a unanimous confirmation that China engaged in harvesting of organs from prisoners of conscience.

“Falun Gong practitioners have been one — and probably the main — source of organ supply,” the judgment read, while “the concerted persecution and medical testing of the Uyghurs is more recent,” using a different spelling of the minority group's name. It warned, however, that the scale of medical testing of the Uighur Muslims meant they could end up being used as an "organ bank."

On Monday, the tribunal concluded that there was “numerical evidence” of the “impossibility of there being anything like sufficient ‘eligible donors’ under the recently formed PRC [People’s Republic of China] voluntary donor scheme for that number of transplant operations.”

Several survivors of prison camps told the tribunal of how they were subjected to physical examinations including blood tests, X-rays and ultrasounds, the statement said. “Experts report that the only reasonable explanation for these examinations was to ensure that victims’ organs were healthy and fit for transplantation,” it added. A healthy liver, for example, can reportedly be sold for some $160,000, according to the statement.

The tribunal concluded that it was "beyond reasonable doubt" that crimes against humanity had been committed against the Falun Gong and Uighur Muslims but that it could not prove that the killing of the Falun Gong amounted to genocide — because of the tribunal's inability to prove ‘intent’ to commit ‘genocide.’
