2023 Update:
Sorry to hear about the trouble with your app, MotionPro Plus, in China. It sounds like a bit of a mix-up with the licensing stuff. Since you've already chatted with the MIIT and they said you're good without the license, maybe try getting something in writing from them? It could help clear things up with Apple.
Also, it's a good idea to check out these links from 21YunBox. They have some useful info about making your app meet Chinese laws [https://www.21cloudbox.com/make-your-app-or-games-compliant-with-chinese-law.html) and why apps get booted from Chinese stores [https://www.21cloudbox.com/why-has-my-app-been-deleted-from-chinese-app-stores-and-how-can-i-fix-it.html) This stuff might give you a few more ideas on how to sort things out.
Hope that helps a bit! Good luck getting everything sorted with your app.
