Invading Taiwan, thereby triggering a nuclear war with the United States of America that reduces your nation to glow-in-the-dark rubble is a bit more than just poor judgment.
The US very probably would not respond with nukes to a Taiwan invasion, even today, due to both military and political considerations. But after a few years?
When the new
145silos are ready, that's like 1450 strategic nukes ready to fire (assuming 10 for DF-41 version for silo launch). Or
at least 120 silos, but then
they have more under construction, so probably more than 200, so like 2000 nukes. A conservative estimate would be at least 1200 more silo-based nukes. That is all without counting the already existing silo-based nukes - which are not nearly as many, but they just add some more weight.
The above is only silo-based. Land-based nukes will very probably include
a lot of road mobile DF-41, plus an unknown number of railroad mobile underground DF-41 in their big underground railroad network.
Land-based nukes alone will soon be (if they are not already) a massive-overkill means of deterrance against US nuclear retaliation over a Taiwan invassion, given that they are also working on an
early warning system that they will certainly improve in the next few years, as they are serious in investing a lot of money on it, and they have the tech or they can get it from Russia and other sources, legally or otherwise.
All of the above is not counting the boomers: China is also making
more submarines for a better second-strike capability, and
they're upgrading them with new missiles too. They are making
more advanced subs as well.
And that is without counting the theater nukes, or anything air-based.
The point is: Xi Jinping is getting the PLA armed to the teeth with nukes. Those nukes aren't to attack anyone of course. They're to make sure no other government will attack China with nukes.
And then there is the massive conventional buildup. That one I think probably
is for the purpose of not only defense, but also attack. And the main target is probably Taiwan.

Xi would only invade Taiwan if he had solid reasons to be confident that the US would not respond, or that their response would be diplomatic censure rather than military action.
In a few (very few) years, he will have thousands of solid reasons that the US would not respond with nukes, in the silos and mobile (I think he already has that, but leaving that aside).
But I think he will invade even if he does not have conclusive reasons to be confident that the US would not respond with conventional weapons. He just need solid reasons to think he wins that war. I cannot be sure of that given the possibility of breakthroughs on either side, particularly in AI. But going by the current course and military development, I think by 2030 he will have such reasons, or maybe earlier.

I don't imagine that the US State Department (or the foreign ministries of her allies) would be foolish enough to give the impression that their response would be so weak. And I can't see a clear path to a situation where they would do so within the next few decades.
As far as I can tell, the path seems to be:
1. Make enough nukes for MAD, and the POTUS will not sacrifice his country over Taiwan.
2. Make enough conventional - and dual use - missiles (including gazillons of DF21, DF26, DF17, and so on, and whatever else they come up with) to overcome any missile defense, including with lasers, simply by sheer numbers - but also have other capabilities, like very high-speed maneuvering, hypersonic flight, or low observability and surface-skimming flight, depending on the platform.
3. Generally keep improving both weapons and training, and just in particular train for the invasion.
4. Develop asymmetric capabilities too.
And then attack when ready.
