The US and China must unite to fight climate change, not each other | Bernie Sanders [ The guardian Bernie op-ed]

I didn’t read it yet is it good lol 
The more I thought about it, the less it made sense; at least how it was built up in my head.
They were just purchasing the chips, and now the USA is trying to block those purchases AND encroach all around the SEA sea while positioning China as aggressors.
Do no Chinese firms have schematics for the chips to be made in Taiwan? Or will this just force China to design their own based on the current top-of-the-line?
I'm not against it, I'm merely posturing questions to learn.
China is still using deep ultraviolet (DUV) chip etching which has a resolution of 193 nanometres, whereas the latest technology is extreme ultraviolet (EUV) which has a resolution of 13.5 nanometres. In practice it means they're about four years behind the other chip manufacturers.
An EUV machine costs about $200 million and that's the one banned for export to China.
Having the schematics isn't really enough - you also need the production lines and extreme tolerances to reliably build the machines.
Some chips are also export banned so Chinese firms have just been buying cloud time on the chips instead.
Longer term it is expected that China will develop a fully self sufficient semiconductor industry.
Semiconductors are hard.
First you need the lithography machines (ASML). Then you need the process development (TSMC, Samsung, Intel). Then you need the EDA tools (Synopsys, Cadence).
SMEE announced a 28nm-capable lithography machine, SMIC has a gimped 7nm process, and Huawei has EDA tools capable down to 14nm.
However, necessity is the mother of invention. I'm expecting the next few years to see an explosion in specialized hardware coming out of Chinese companies.
