On top of that, the British only introduced a pretty limited form of democracy to Hong Kong shortly before it was supposed to relinquish control over the territory
On top of that, the Chinese dictator crushed democracy with military and police force in violation of the unification agreement – proving 100% it absolutely can not be trusted.
The PRC saw this as an attempt by the British to continue interfering with the right for Chinese self determination.
The Chinese have no rights whatsoever in the PRC regime because the Chinese cannot chose their own leaders and determine their own country’s destiny. By “right for Chinese self determination” you actually mean the DICTATOR’s right (one single individual!!) to prevent one billion Chinese citizens from running their own country as they see fit.
Ukraine needs to bring in a South Korean resettlement team and tell the North Koreans all they need do is surrender and get their free tickets to South Korea.
