The risk is that other EU countries would adopt similar policies and create long-term problems for Taiwan and its 24 million citizens to freely determine their future.

More like create problems for the US to freely determine Taiwan's future

Serious question though, can it still count as self-determination? Afaik the pro-reunification/pro-PRC side has been suppressed for decades, especially at the start of the occupation, and Taiwan is constantly bombarded with anti-PRC propaganda, all thanks to the US

If we pretend history doesn't exist and we do what libs did e.g. in Gaza assuming it all started on Oct 7, then sure, people want to separate from the PRC, they should do it

But this ignores how they got into that position and what "independence" entails (becoming another Ukraine). You get pushed into a direction and then you're made to think you got there of your own accord
