But that attempt will fail.
No matter what happens, the Chinese government will not allow its hi-tech giants to be destroyed.
They'll be supported until American technology has been completely removed.
That is easier said than done. Huawei smartphones, 5G, cloud, AI which one of them don't need server chips, FPGA, Kirin, Tiangang, Kunpeng, and Ascend. No one knows how much chips Huawei has stockpiled but it is pretty sure that Huawei smartphones would run out of chips in the high end within a year or less. Some analysts even believe that 5G base stations chips would be run out by first half of 2021.
I don't doubt the Chinese government support of its high tech sector. However, for companies such as YMTC which is relative young, any sanction would be devastated. Even SMIC might find it difficult to survive without massive injection from the Chinese government. Huawei might be forced to enter into some new industry for survival. In the meantime, 5G expansion would be delayed in China, Huawei investment in chips would lag as it focuses to become IDM.
The game is not just to survive but to advance and to close the gap between China and the US. However irrational is Trump, his administration has seriously disrupted China's technology progress and advancement. The success would be define by your ability to retain best talents and continue to invest and keep up with the latest tech even though you can't produce and use them. And Americans don't need to destroy your high teach giants but just need to weaken them like they have done to the Japanese tech giants in the 80s and 90s.
