Learning from Hong Kong experience, education must be controlled by the central government to prevent foreign teacher infiltrations and anti-national curriculums in schools which was a main factor influencing Hong Kong students.
Another sector is media like TV, newspaper and Internet also need to be controlled.
From previous discussions, the only reason why the pitfalls of 1C2S came to a head was because of the power imbalance that existed between HK and the mainland. It was a small city, but was the strongest economic engine in China at the time. SZ as a tech powerhouse was built on a foundation that HK laid.
In addition, PRC made 2 major errors in governance.
1. Central government was overconfident that HK local government could solve the national security law issue on its own.
Although western media likes to lie and say “China changed the ‘deal’”, the reality is that the Basic Law always established the National Security Law as a requirement. This messaging is showing how western agencies exploited this weakness. Macau passed their NSL without incident within a few years of reunification.
2. Central government did not act fast enough to rein in bad actors as you pointed out.
As I have mentioned before, there is no power imbalance with Taiwan. Semiconductors are not important enough to move the needle, if anything Taiwan’s semi industry would benefit far more from peaceful reunification with mainland customers no longer blocked by the DPP/US. Taiwan’s decrepit power infrastructure could be renovated and restored with new Nuclear tech and clean electricity tech from the mainland without DPP barriers, unlocking previously unrealized economic benefits.
The central government should have learned from their previous mistakes, otherwise it’s their own failure. IMO, if the 1C2S option is available, then it is totally workable without repeating the HK mistakes.
