Keep an old app version in China country due to callkit

We have a concern regarding the behaviour of the App Store when publishing a new version of an app we already have. This app is currently in version 1 without callkit.
Nowadays we are evolving this version to version 2 (same app, same name...) to be compatible with callkit. But according to guidelines we cannot use callkit (we must remove library) in China.
So our intention is to publish version 2 in all the territories except China.
So our question is:
  • when we publish version 2 in all the territories except China, will be version 1 still available in China?

  • if not, what are the chances? We cannot use version 2 and publish it in China since it includes callkit. Should we use another app in that territory?
