Because the EU respects the One China policy (like virtually every UN member) and because the EU does not have hundreds of military bases surrounding China.
Doesn't seem like USA is respecting anything.
The US’s position is that it’s up to Taiwan to decide its own fate. And will not allow china to invade and force Taiwan to join China.
This has been the same position for the last 70 years. Taiwan has been an ally of the US long before the CCP was created.
I guess except for when the US sold the UN seat to China because it’s convenient to them at the time?
