It's all politics.

From my point of view, I see this problem as a political conflict far from scientific development, which began after the decision to ban the entry of Apple devices into China.

Both the Chinese Government and Apple claim that the reason for Apple not being on the list of approved devices for state purchase is that Apple did not apply to be on the list. whether this is true or not, both are claiming that there is no ban.

At the scale of a small company, standardising on devices makes sense, so may be even more so for a state. Choosing a standard platform would have advantages, rather than allowing people to choose any device and requiring that IT departments ensure that they are supported.

If AI / 5G will dominate the 'fourth industrial revolution' then shutting out competitors makes sense - whether implicitly by trying to get proprietary standards accepted, or by having loss-leaders to build market share (with investors hoping that in the end a profit will be made, or at least that an IPO will allow them to cash in), or explicitly, by standards (with certification required), or straight denial of certain products.

This story has been around a long time, before the first industrial revolution. Sometimes it has played well, sometimes it has resulted in isolation and loss against the wider world.

Many thanks for your answers. There must be a political and technical reason but given AI and telecommunication across the web being key to all us, its time both sides find a way to keep the peace.

It's all politics.

For many years of the last century we lived a cold war between the USSR and NATO, now we live the second cold war, facing China and the United States, like all war, there are casualties and attacks and battles and this is a hit of Google (USA ) to huawai (CHINA)

There is no right wrong answer here. Its strategic anticipation and negotiation tricks and tactics. All available stories are just propagated perception.

For reality, this question need to be asked in different way like really who controls the google and Huawei from backened and how it impacts the future for those companies and govt bodies? Try unfolding it continuously, you may reach somewhere where there is huge battle on.
