This is the least surprising thing ever and was highly suspected when DeepSeek released their original model.
We've also seen this with sanctions on Russia but they still somehow bought a bunch of TI chips for missiles [1].
As many here know, the US restricts the export of certain technology to China because reasons. This includes lithography machines from ASML, a Dutch company, who have a monopoly on the latest EUV processes. It's geopolitically interesting that the big buyer of ASML products are TSMC in TAiwan as well as Samsung in South Korea (and possibly Japan?).
I expect this will become a national security issue for China and long-term you will see China try and replicate the best lithographic processes and chips such that the gap will greatly narrow. This will take years and involves a lot of depenedent industries but of anyone China has shown the willingness, ability and resolve to pursue decades-long infrastructure and national security projects.
In the meantime, bans on GPU exports to China will continue to be circumvented (eg [2]) and honestly there's no real reason for those export restrictions anyway.
