The actual products or the volumes being shipped were not mentioned by the CEO
Well no, he wouldn't, otherwise Trump will make sure they are added to the list...
Micron has begun to supply a "subset" of DRAM to Huawei in the past fortnight after discovering those products are not covered by the sanctions that prevent Chinese firms buying components from US suppliers. Back in May, US President Donald Trump declared a national emergency and signed an executive order to prohibit …
To be fair, most of Micron's drop was due to prices dropping for DRAM and NAND which started before the whole China thing. If they listed those amounts in bytes the decline would be far smaller.
Trade between China and the US will be permanently impacted on both sides by this, with China finding alternative suppliers for farm products and ramping up efforts to make stuff like DRAM/NAND themselves (they already do, but at low volumes) and US companies moving at least some production out of China (but to other cheap countries like Vietnam, it isn't coming back to the US)
As I've said before, once this starts hurting the US economy badly enough Trump will be forced to cave. China will not blink, because they know Trump put himself over a barrel by starting the trade war when he has to face an election soon.
The fact both sides will permanently lose markets with each other is why trade wars are always a bad idea, unless the things being traded are not available elsewhere. Trump is simply too uneducated to know this. He'll be forced to cave, but will claim victory when things go back to the way they were, like he has for USMCA, his replacement for NAFTA which is almost identical to NAFTA in every way.
There is one certain way to drive innovation in a county, and that is to attempt to cut it off its access to technology. Whether from wars or political blockades, the targeted nation initially suffers, but quickly develops its own technology, and often ends up with products better than it had access to in the first place.
And it's not going to take them all that long in the doing. While the total quality of the engineering labor force is rather uneven, they have at least as many, if not more, good to excellent engineers as all of the US. Something that gets missed in these sort of political-economic calculations.
