TBH UK never had the chance because PRC saw through their games. TLDR UK wanted to maintain influence post handover for their investments, but like most other colonies on the fading empire they had no leverage, i.e. negotiate to turn HK into self administered territory (like Singapore)... along with UN decolonization rules meant engineering pathway for HK independence. PRC keked and said fuck off and promptly removed HK from UN list of non-self governing territories. There's a reason UK/Patton had to jam in HK liberalisation efforts last minute to increase UK influence post handover and not before... because if they did it before, i.e. pre 90s there would be so much anti colonial and pro CCP sympathies that political freedom in HK could be contrary to British interests. HK was just another Suez, symptom of UK weakness, not any one man.
