No, it's constantly accused of such by the Falun Gong (a religious cult that officially believes that David Copperfield is a real wizard), and a lot of western governments looking for something to attack China with amplify the accusation without any evidence. A good way to do that is to cite the conclusions of an "independent tribunal" that no one had heard of, whose only concerns are spreading the consensus about the evils of China and the Chinese, and who are mysteriously funded.

Western governments attack enemy regimes by funding religious cults (with associated militias) like MEK and Falun Gong (which are allowed to have multiple OTA TV channels while the Chinese government are banned from most of the internet.) They also fund fundamentalist Islam in northern Africa, and neo-Nazis in central Asia and eastern Europe.

It's important to dismiss "strong suspicions" from semi-anonymous sources and ask for actual evidence, circumstantial or not. Propaganda is supposed to be what we dislike about China. We shouldn't help spread innuendo if that's actually a value we have.
