@manqiangrexue, the US is perfectly free to not sell its products to China or Huawei if it wants to. But they have gone way beyond that. Strong arming other countries not to buy Huawei's products, when that failed (even their lapdog the UK balked at it), they now threaten any suppliers of Huawei who also deal with the US market (not just US companies) that they will be sanctioned too.
They are leveraging their market power to kill Huawei. If this was economics you would see what it is. It is an abuse of monopoly power or a dominant market power.
This is playing dirty no two ways about it. Huawei was chosen not for any security concerns or any hogwash like that, it was simply because it is a Chinese tech champion.
I said this before but Trump, when he was a real estate developer in New York, surrounded himself with gangsters. His construction projects were one of the few where workers never went on a labor strike because of that. He's got a mobster mentality. All his talk about wanting a fair deal is hogwash. If he wanted that he could have renegotiated the import-export tariffs first on a fair basis. But, like I said, he has a mobster mentality. So, just like any mobster, his idea of a negotiation is you enter on someone's establishment, break some things with a crowbar, and then impose your conditions. This is something straight out of the Sopranos or the Godfather.
The fact they directly went for the Huawei founder's daughter is also something straight out of a mobster's playbook. You would think there are other ways to do a lawsuit.
