I tend to agree with you. I dont think that other nations will join the US in tech sale restrictions to china. They tend to need china more than the US does, and what would they gain with it?
But i can see the US adding more of its own restrictions to tech exports to china.
But the US adding more technology restrictions is illogical and self-defeating.
It forces companies in China (and in Europe/Asia) to develop alternatives.
The majority (circa 60% ) of microchips in the world are either:
1. Consumed by China
2. Or used in products that are exported from China
And China already spends more on R&D than the USA, as per the National Science Foundation reports to Congress.
So after 3-10 years, you can expect Chinese companies to have removed all US technology content.
