I don't believe the Chinese did. The Chinese government has what 5 million people in concentration camps and they claim that they don't
China is extremely behind in technology so that is why they are always sending immigrants to the US. They pretend to be US citizens get jobs at apple and boeing and then they send everything back to china in a usb drive.
China is known for faking GDP statistics, and they build massive empty cities to fake economic growth
They jail anyone who is skeptical about china's claims, if I was in China right now I would probably be in jail for questioning the governments moon landing.
