I agree with you that China has placed restrictions on foreign company doing business in China and not Chinese companies doing business in China. This is a big issue and I think China should reflect on this. But what I am saying is China at the government layer has not targeted an existing foreign company with billion dollars sales and many employees whose livihood depends on the company and limit it in a fashion that it cannot function. Huawei employes 10000+ people and many local economy depends on the company. What if the company goes under because of US influence right now? People lose their jobs their homes and etc? Would you say that through US actions it has directly negatively affected the civilian lives of another country? I think one has to consider the severity of ones attack. It's one thing to put obstacles and roadblocks, but it's another thing to kill another all together.
China limits all foreign companies from accessing it's market. The true reason is to provide a safe heaven to allow local companies develop it's own technology and capability before killed off by foreign companies. During 80s when China is start to open up the market, China has literally no private enterprises with good capability on it's own. Foreign companies from US and Europe have too advanced of technology and scale simply because they have been developing much longer while China was being war ravaged. These companies would easily take over the china market and kill any local enterprises. Look at the affect of the ban, China now as pretty good technology on it's own and local companies with the scale that can compete with foreign companies. Foreign companies now entering China find difficulty partly because of the regulatory environment but also because of local competition is much stronger. I would argue that Apple sales decrease in China is not mainly from regulation but competition from Huawei xiaomi and oppo. Now contrast this with Europe and Canada, especially in the tech market, no one has home grown technology companies that are big enough to compete with the US. Many homegrown companies went away because of it cannot compete with the US. Is would surely damage local economy right? I think the advantages and disadvantages to free market must be carefully balanced.
Which foreign company has China destroyed using it's foreign policies? What China is doing is limit foreign company access to it's market. The equivalent would be US saying Huawei cannot sell in the US, which is totally fine. But this case is not. Huawei is stricted from doing business with any US entity. This order is essentially designed to completely destroy Huawei and damage Huawei in other countries whom might not side with the US or shares US concern. Keep in mind that in the situation where Huawei buys a component from a company not under US control, say a chip from TSMC, if said component contains any US IP or made component, Huawei still cannot buy it. In the world of technology, this is crippling. Regardless of which political camp people are on, I think this case demonstrates regardless how much US companies sell themselves as global and trusted, they are still US companies and beholden to US politics, and can be used as weapons in advancing US political agenda. Second, this also demonstrates as digital technology becomes as fundamental as electricity, water and air in each of the world's society, a lot of it is monopolized by the US and you are under the hands of the US to use said technology. I think it's very important for each Nation to develop it's own digital technology and true open source systema(hint Android for it to be truely useful is not as open as people think). I think technology people should focus on providing every person on Earth equal access to technology to improve everyone's lives.
