Not even in US this phenomenon is very strong. US protects its corporations with political and military means all the time, so I am not sure what separation you are talking about. In words there mightbbe some pretense for separation, but actions show otherwise.
To me from Western Europe the state and corporations are... comparable to families and sports clubs. Nobody would want to merge them for tons of reasons including personal freedom (here: separation of public and private spheres), effectiveness, responsiveness, avoidance of conflicts of interest etc. But coordination makes sense.
Something I have noticed about large Asian companies is that there is much less in-fighting between parts of the organization, which can make up for other disadvantages they may have. In large Western corporations it seems to be everyone against everyone in mid-level management. At the lowest level it mostly looks like inexplicable inefficiencies and stupidities.
Not true. My observations are opposite, however, I am not disapproving what you said, but I don't think there is a conclusion to make.
However, if you prove yourself as a capable strongman that doesn't take objections, then in Asian companies, under the certain circumstances/directives, I believe you can have much more dictating power over your subordinates, which can go to great extent to have them sacrifice all other aspects of their life except work.
For example, Tencent carries out a stunt to have its staff run a 24 hour 2 shifts schedule to deliver PUBG on the mobile devices, to beat its competitors on speed, which I don't think is possible in Western countries.
Freedom for the government to do what it wants with the help of corporations, and for individuals to decide to join those activities and participate freely.
In East Asia, the Japanese model, that later adopted by both South Korea and China, relies on the exact opposite. The government directly involves in guiding and shaping the economy. And they are smart in doing so, with the corporations being their vehicles to implement its policy and they are ones to picking the winners. So it is not like Planned Economy like the Soviets did, instead they are trying to embrace and take advantage of the market to better advance its objectives. Instead, here in US, corporations are more sensitive and faster than the government to propose new economic initiatives, while government just sits aside as the shepherd to prevent disasters.
If you ever being able to read material from CJK countries, the government in general has a much bigger power and responsibility, and when problem happens, the societies' instinct is to push the government to act on it.
But Huawei might be still a special case among of these. It is a weird company though, which doesn't need to respond to its share holders and yet participating actively in open and competitive markets.
