I live in a Chinese dominated country. I can tell you this is because of the absurd nationalistic view that the Chinese hold. For example, I know atleast 5 co-workers who sold their iPhones to get a Huawei when the sanction was made. Part of the reason was Huawei phones' prices (even new ones) drastically dropped when the announcement of no more Android support was made, so these guys (and girls) got it at a super go…
Nothing absurd about it. The US government is trying to coerce the Chinese government. Great time for them to feel nationalistic.
> I tried to understand why, so I threw many arguments at them such as Huawei was actually caught sending data back to 3rd party servers in China and I even tried explaining maybe the sanction is on them because they broke the law/agreement w/ the US.
The core of that argument rests on the idea that Chinese people should accept that the US can dictate how they deal with Iran. And that the US can choose how to enforce compliance to that law. Both of those assumptions are flaky at a basic Chinese-people-should-agree-with-this level.
International rule of law would be nice, but the US doesn't particularly constrain themselves by rule of law in the international sphere - they've invaded a lot of countries on flimsy pretexts. That is much worse than trading with people. After that example, why should the Chinese worry about international rules that are inconvenient? For all the fact that their government is brutal and terrifying it hasn't invaded anywhere in the middle east in the last 20 years.
