Well-made CNC machines are a controlled export item in the U.S. if they have the ability to precisely machine certain materials to create certain parts. See recent news stories about Haas CNCs churning out Russian weapons.
Multiple axis CAM software is also export controlled.
The folks who make the hobbyist machine I linked have a page on this:
I find that quite fascinating. So it's illegal to export a high-quality CNC machine from the US. But, apparently, it's legal for China to sell a clone of that machine to those exact same people who wouldn't be allowed to buy an original from the US.
