Re: @FozzyBear - You're wrong.
"Using national security concerns to grab a high-ranking executive outside the US borders is not the right way of doing it. "
Not sure where national security concerns come into this one. I get as sick as anyone else about the US government's delusion that US law applies anywhere else in the world but the US, but that doesn't appear to be the case here.
The allegation is that US made products were sold to Iran by Huawei, which is a crime in US law which was committed on US soil.
The sale was allegedly committed using HSBC Holdings Plc for the financial transaction, which is using the US financial system to sell goods to a sanctioned entity, which again is a crime in US law committed on US soil.
If Huawei lied to HSBC Holdings about the destination of the goods being sold, that is financial fraud in US law, again commited on US soil.
You see the pattern here?
The arrest of a senior Huawei executive is probably due to the fact that when ZTE were caught doing the very same thing (and fined a couple of billion dollars for doing so) they allegedly lied about disciplining the senior executives who were responsible for running the operation. The detention and extradition request is a way of ensuring that this does not happen again.
It would be naive to ignore the political implications of this detention, but in this case at least, US law does appear to have been legally applied.
