We also can’t blame subsidy. All countries subsidize their industries.
This video on the auto industry covers a different industry but has a lot of the same rhymes as far as China’s strategy:

The gist of it is that China does the following:
1. Treats low margin industries like mining and utilities as areas to focus investment and come up with incremental improvements, making those available to all companies. The West, by contrast, allows private companies to handle those industries, who logically don’t bother investing in them since their investors consider those basic industries to be low-value segments of the production chain. But now we see those advantages in China where investments have been made (e.g., the best battery chemistries and mining, the cheapest power (when was the last time your local utility company focused on reducing pricing?)).
2. Because all companies in China have access to the same excellent infrastructure, they must compete furiously on quality of their products.
3. China allows foreign competition so long as they operate in China (see: Tesla) further insisting that their domestic products be globally competitive and that foreign products sold in their country benefit their local ecosystem.
There is (was): attracting the best minds around the world to a free and stable society. Trump voters threw it all away because they couldn't stand non-whites coming to America and doing better than old stock Americans.
There's nothing special about anything we design in the US other than time and money commitment to create it. China did have some espionage of course going on, but the vast majority of shit isn't some secret. And with the US shitting on China with restrictions, we increasingly caused them to invest time and money into things they otherwise would have passively accepted as coming from the west. ASML sees the writing on the wall for themselves in particular.
The US has generally resorted to propaganda rather than addressing the self-inflicted structural conditions responsible for the erosion of our dominance. China also conducted a broad, sustained, large-scale campaign of IP theft across almost every industry.
Obviously there is no natural law preventing China from innovating (We have treated political liberalism as a prerequisite to innovation in a way that was always partly self-congratulatory), but it's also obviously true that the speed of the gap closure is due in significant part to theft.
That doesn't change the fact that they are now a legitimate competitor who has gotten a lot of things right (and among these, some things that we get very wrong) and probably actually leads in some areas.
China can certainly design an inflatable barbecue. China can certainly biuld an inlfatable barbecue. But will the chinese people ever want and buy an inflatable barbecue? ... never. That is why the US will remain the premier consumer economy.
