These types of "computers" are pretty simple electronics. All the complexity lives inside the "System on chip" - the engineer then picks a few supporting chips and makes sure the signal routing is matched. I wouldn't be surprised if the whole thing is based on a reference design from the SoC designer.
In this case, the west basically already competes - this is pretty similar to the raspberry pi zero. There's plenty of Western designed SoCs - which is where the complexity and IP lie.
For example, the Pi Pico comes with nice SDKs, comprehensive documentation, and can be flashed with a simple file drag and drop as they made it show as an USB drive.
So I'd say the West is still leading on this...
