Let's see:
The US takes measures vs Huawai =>
1) destroying or severely containing the company =>
2) reverse tide on China's tech rise =>
3) hamper BRI =>
4) foil plans re currency.
Well well. The US can do all these things with a "surgical strike"! Seems absolutely terrifying, but if you examine this scheme, there's a lot of holes.
Take the first step of this sequence, for example. Huawei is not exactly dead yet. It's handset business is affected, but I see no indications that 5G rollout has been hampered in any serious way. Its cloud services should be completely unaffected, and only part of it's product line in servers will be impacted. But Huawei is a resilient company and it is already entering new lines of business to compensate. The talent, organization, and good morale of the company will continue to serve China well.
But suppose Huawei was actually destroyed, as you say. The second step in the sequence says China' tech rise is reversed. There's no logic in this at all. The number of researchers in china won't drop. China has more people involved in R&D than the US already for several years, the the gap is only growing. I believe the university system is expanding again, after reaching a plateau about a decade ago. If Huawei is the top in 5G, the Pentagon says the Chinese military is beginning to field some technologies which the US does not have. Moreover, China is spawning tons of tech startups, and the country in 2018 surpassed the US in the amount of Venture Capital utilized for the first time. Huawei has been the big story in 2019, but in the last couple of years, it was all about BAT (Baidu, Alibaba, Tencent), mobile payments, sharing economy, self driving cars, etc. Huawei has played a good role, but China's tech rise is not the result of one company. Rather, Huawei is the result of China's tech rise.
The third step in the sequence says that China's loss of momentum in "tech rise" will hamper the BRI. I'm not sure why this should follow either. Cellular networks built with Nokia or Ericsson equipment can be used to develop the connectivity China and everybody else wants. And of course, none of this will affect the fiber optic technology for internet, or the pipelines, railroads, roads and power plants. GE and Siemens are being used for the latter in many cases, and it turns out "Western" watts can turn the lights on just as well. Perhaps there will be a bit less Chinese money for the initiative, but political attitudes and interference are playing a much bigger role in holding things back now, and not lack of funds, equipment, or materials. Moreover, the BRI is taking on a life of it's own, as quite a few players see benefits. This includes not only recipients of projects, buy players taking part in building them (Russia, UAE, Switzerland, Japan, to name a few).
I won't bother with the fourth step, as it's too far into fictionland, but I think it's clear the consequences of this "surgical strike" will not be the ones intended, assuming
@Arkboy is right about American reasoning. None of these hopes will be realized.
