There is some decent Chinese stuff. Sometimes it's hard to know though with the flood of crap. For example Anker seems consistently decent, but anything that sounds like Qihoon or Xiyomao or whatever random brand word they pop into existence on the other hand...

they keep the good stuff for themselves.

Do they? If anything, I believe China's been exporting the high-end luxury items because they have absurd margins in western markets. Meanwhile, the good-enough goods stay at home, because it isn't worth the time or effort to sail them across the ocean and market them.

I guess Temu and its peers have changed that, to a degree. But so much Temu crap just gets bought up by local American drop-shippers, marked up to American prices, and rebranded as western equivalent merch that it feels like much the same.
