I get all my graphic cards from china because it's the closest foreign country to mine, and my suppliers have told me what was going on with crypto miners in China, it was like a war on drug, the government hate the sight of Asic miners and only those selling to other foreign countries are left to do their businesses, you can't be in china and be mining Bitcoin.
That sounds bad for those who are miners, and that also means they have to evacuate or migrate to another country if they want to continue mining. In terms of technology, it is arguable that China is one of the leading suppliers of some technological parts like what you've said graphic cards. Years ago, I have also ordered from them a raspberry pi to help my former classmate about his robotics competition. For us living in Asia, China has become a primary source of those techs and aside from we didn't have to spend so much for shipping fees, they also offer good quality products depending on which supplier you chose. At that time also they are the ones who heavily supported crypto and mining industry, it's just funny how the tables turn and now they are against the very idea they supported.
