If we look at 2022 financial results of Chinese SME, we can see many of them, including the biggest ones, achieved >50% revenue increase, and Q1 2023 has started great.
This was unbelievable just few years ago and would had never been possible without the US threats. This gives the measure of how much short-sighted US policy is.
Since the 2018 Huawei ban under Trump, and continuation of the same policy by Biden administration (because neocons ruled US foreign policy then, and rule it even more now because current president just reads prepared scripts), US has literally enabled a diverse, healthy and strong Chinese SME market out of thin air. Well done US hawks! Chinese government would not have been able to do better.
The US has long complained about China's industrial policy. The irony is that the US sanctions have become a much more effective semiconductor industrial policy ..... for China. Chinese government has announced and implemented a series of policies and regulations to promote and develop semiconductor industry since 2000. The direct results were lackluster; much of China's progress in the industry since then have been accomplished by the market and private companies (Huawei, SMIC, etc.). One of the biggest reasons is that Chinese companies preferred to work with more established international companies, for good reasons. Again, Huawei and SMIC were quite representative here.
The US sanctions are now existential threat to Chinese companies in the semiconductor industry and the broader IT industry, forcing them to work with each other. To be sure, there are and will be short-term setbacks, delays and cancellations, but if you are a long-term observer of Chinese tech industry like me, you know that China will always come through and achieve higher than if there were no sanctions in the longer-term. This is no copium, but backed by numerous precedence. In fact, I would argue that China is probably the only country in the world that can accomplish such and develop and sustain an independent and advanced semiconductor industry. Some argue that Japan currently has the most self-sufficient semiconductor industry. But Japan misses one critical ingredient: market.
