There's no question that the Chinese are doing sketchy things, and there's no question that US companies do it, too.
The difference that makes it concerning and problematic that China is doing it is that with China, there is no recourse. If you are harmed by a US company, you have legal recourse, and this holds the companies in check, restraining some of the most egregious behaviors.
That's not sinophobia. Any other country where products are coming out of that is effectively immune from consequences for bad behavior warrants heavy skepticism and scrutiny. Just like popup manufacturing companies and third world suppliers, you might get a good deal on cheap parts, but there's no legal accountability if anything goes wrong.
If a company in the US or EU engages in bad faith, or harms consumers, then trade treaties and consumer protection law in their respective jurisdictions ensure the company will be held to account.
This creates a degree of trust that is currently entirely absent from the Chinese market, because they deliberately and belligerently decline to participate in reciprocal legal accountability and mutually beneficial agreements if it means impinging even an inch on their superiority and sovereignty.
China is not a good faith participant in trade deals, they're after enriching themselves and degrading those they consider adversaries. They play zero sum games at the expense of other players and their own citizens, so long as they achieve their geopolitical goals.
Intellectual property, consumer and worker safety, environmental protection, civil liberties, and all of those factors that come into play with international trade treaties allow the US and EU to trade freely and engage in trustworthy and mutually good faith transactions. China basically says "just trust us, bro" and will occasionally performatively execute or imprison a bad actor in their own markets, but are otherwise completely beyond the reach of any accountability.
