You'd think? The US is the only nation that is in a position to do anything about it. While sanctions won't compel the CCP, it could hurt them enough to prevent further cementing their hegemony.
> Just try US sanctions and pushing the EU, Australia, Japan, Canada not to conduct any business with China.
You dont to sanctions to countries that provide most of your goods without a viable alternative. Sanctionning Iran does not change your daily life. Sanctionning China would suddenly make a large impact as to what you can actually buy and at what price.
The way to do that is to simultaneously open up trade with anybody else. Literally offer a free trade agreement with anybody that also sanctions china.
Taiwan can't compare with China in terms of production capabilities right now. And other countries in Asia don't produce the same goods as China either.
Economic force is a completely different matter. It's basically orthogonal to nukes. Tbh I doubt that would work either, and it would hurt the West tremendously. But it's at least something that is not totally absurd on its face.
