Low quality Chinese plastics are known to contain heavy metals like lead or cadmium. I would never trust a random Chinese manufacturer that isn’t vetted by a much larger organization that I can actually sue for negligence, etc.
China themselves are doing a much better job on this front than some random lawsuit would. For instance the baby milk scandal from China [1] was globally publicized largely because it led to the death of 6 infants. China's prosecution of the company included complete dissolution of the company, 3 death penalties for the heads of the company, life imprisonment for middle men, and even prison terms for some wives who were not even involved in the business. Compare this against what happened to Bayer who knowingly sold HIV infected blood products, infecting tens of thousands with HIV and subsequently AIDS. [2]
There's a reason the "shocking" examples they give in this article are now things like "kids’ shorts with drawstrings longer than regulation length, which cause a trip hazard." China is an export economy and takes this stuff pretty seriously, which is why I also think articles like this are mostly about manufacturing consent for future actions. We gotta get ready for the next war - Ukraine and Israel are getting so boring!
This reply amounts to "China bad!" Sadly the average American or Westerner can't really be trusted to be objective or rational when it comes to China, ironically because of American propaganda.
under what circumstances would you actually for real sue someone? this seems like a thing that is almost certainly NOT gonna happen, even if they did insane shit.
