Are there? You can’t open a business in China without it being majority Chinese owned. There are plenty of companies doing their manufacturing in China, but every example I know of the wforeigb company contracts the Chinese company to do the manufacturing. Often they’re even further removed, such as Apple who works with a Taiwanese company who just happens to have their manufacturing in China.
But still, not sure if they would give up the low cost of manufacturing for this. Frankly, the regime makes that possible.
