> To keep this in context, the current Hong Kong SAR government is democratically elected[6] according to the provisions of an international treaty signed by the PRC and the UK which took effect in 1997

No, this's misinformation. The HK government isn't democratically elected. The CEO of the HK government is selected by a committee appointed by the CCP. See https://en.wikipedia.org/wiki/Election_Committee_(Hong_Kong)

Quote: The Election Committee is a Hong Kong electoral college, the function of which is to select the Chief Executive (CE).
