China thinks it can do without U.S. technology, that it can go it alone. It may well be right. From Hua Bin at unz.com:
China is banning Nvidia chips in an unexpected second order effect of the US tech embargo

Since Trump and Biden launched the tech and trade wars with China, I have written several essays arguing that Beijing should pursue a full decoupling with the US for national security and economic competitiveness reasons.
It seems that is happening right now. Beijing just banned its big tech companies from buying the Nvidia H20 and RTX 6000D chips. Nvidia developed these two GPU AI accelerator chips specifically for the Chinese market in compliance with the US ban of advanced AI chips to China.
Beijing just threw back the trade embargo playbook in Washington’s face. This is a textbook example of how an ill-conceived coercive policy blows up in the face of the perpetrator. And another case study of how the far more intelligent technocrats in Beijing have outsmarted the short-sighted political functionaries in Washington.
Let’s examine what happened.
Starting in Trump’s first term, the US regime has upped the antes in containing China’s technological rise. It first banned US chip sales to Huawei in an effort to destroy the telecom and mobile phone giant. That failed miserably but as expected, Washington’s default option when faced with failure is to double down.
During Biden’s time in office, he further escalated the tech war by banning AI chips, software, and even lithography machines to the Chinese market as a whole. The explicit aim of the tech bans is to stop China from reaching the US level of AI development.
Intel is small hat and reports back to base.
If you aren’t doing the latest video game or flight sim then you won’t need Nvidia cards.
