Well the big problem with china is that they do not respect international law when it comes to technology theft. But that argument is very weak when it appears that a lot of what they do is out in the open for anyone to replicate.
There isn't one global "international law" for copyright. There are treaties that countries negotiate with each other.
If the USA wanted a copyright treaty with China bad enough, we would negotiate one. China is not breaking any laws here, international or otherwise.
No major power respects nor cares about international law.
Intellectual property is part of WTO agreements but enforcement is domestic.
US companies do it too, regularly, they simply hire and poach staff from competitors.
Proving it to be IP theft is difficult unless you can prove documents being passed. But often all you need is the know-how of the hired talent.
yeah, America is totally out there respecting international law.
"problem" indeed.
That's how you catch up when you're behind.
Now the US is behind in EVs can you guess what they're doing? [1]
