Must admit, since I left Beijing and moved back to the UK, I haven't really kept up to date with China-Taiwan tensions or HK-mainland shenanigans or kept up in any great detail with wider Asia-Pacific region politics.
With that caveat in mind, I reckon not just the Russian invasion of Ukraine but more importantly the more recent (non-)reaction to Israel's attacks on Gaza, with the global superpowers basically turning a blind eye to genocide, war crimes and a possible huge land grab, will have had the effect of emboldening the Chinese authorities in terms of any plans they might have to physically annexe Taiwan.
Lesson learned from Russia v Ukraine is that while US and other Western allies might provide financial/military aid, and they might provide advisors, they're not going to wade in and commit any ground troops, and any air or sea support will be on the periphery.
So in the event China invades Taiwan... so what? What are the US, UN, UK, etc going to do? Again, while they might provide financial and military aid and advisors, they're not going to commit any ground troops, they're not going to risk destabilising the region any further, bearing in mind US military presence in South Korea.
North Korea (allied with PRC) and the Korean peninsula is a can of worms that they won't want to open.
So there will be lots of condemnation of China, but in practical terms? What? Sanctions? They will kill the US automotive industry stone dead. Ditto lots of parts of the tech sector for which China and/or Taiwan are the major sources of components.
Think back to how much chaos was caused when the Suez Canal was temporarily blocked by that container ship. Or delayed deliveries when shipping had to be rerouted round the Horn of Africa due to an upsurge in incidents of piracy.
Given how many industries rely on 'just in time' supply chains, any sanctions or other disruptions due to military activity will have a disastrous knock-on effect on the global economy.
Ultimately, the global superpowers won't care very much about Taiwan or its people, they will care about the impact on their own economies and their own companies and population.
