Just reading over the Wikipedia page, I see that this is contested, but the argument that it has been happening are much stronger, and the only cited counterargument involves the demand for immunosuppressant drugs, which I would be unsurprised to learn that literally any developed nation has the capability to produce themselves.

Why do you think this is false?

It was literally just made up by Falun Gong cultists because they believe they have superior organs thanks to their magical qigong routines and the organs are used to bolster the health of gommunist officials. You're literally just parroting dumb Epoch Times bullshit.

Wikipedia isn't a source (it is, at best, a summary of elements of a collection of sources), pick an actual source that looks credible to you and I'll do my best to explain to you why it's worthless because this is a crank conspiracy story.
