China is a huge country with a much bigger hardware industry than the US. Seems to me it's normal not everyone there is working with the same technology. It's just a massive number of different companies doing different things.
That being said, RISC-V is gaining a lot of traction. I wouldn't be surprised if it starts to become a real challenge to ARM in the next five years. You just need mature tooling and better cores. Probably also need a wider variety of smaller cores for embedded applications available at the right price points.
