Here’s another hint. In the ongoing dispute between the US and the People’s Republic of China—the latest example of which is the lack of US visa renewals for PRC journalists—Hu Xijin, Editor-in-Chief of Chinese and English editions of the PRC State organ Global Times, had this:

From what I know, given that the US side hasn’t renewed visa of Chinese journalists, Chinese side has prepared for the worst scenario that all Chinese journalists have to leave the US. If that’s the case, Chinese side will retaliate, including targeting US journalists based in HK[]

Including targeting US journalists based in HK.  So much for Hong Kong’s semi-autonomy. It’s plainly a fully absorbed satrap of the PRC.
