First report was written by a CISIS analyst. I don't trust ANYTHING coming directly from CISIS when it comes to China after the whole 2 Micheals turned out to be a bunch of BS. Secondly I would need two backup reports for any Bloomberg article that involved US Poilics, China, or me being on fire before I would believe it.
The third link and its base source was interesting. Here in Canada I have not heard of any restrictions and, outside of the hobby, I haven't heard of component prices or availabilities and this was something that flew under my radar. I knew about the Russian use of Chinese parts, but this is the first I have come across the fact that China is also restricting parts. Thanks.
