If this is happening, I hope Apple says no to the CCP when they inevitably ask Apple to do the same.
Could Apple use that new CSAM-hash-comparison feature to accomplish something similar?

Nevermind - it looks to me like this mechanism is just for letting Apple know if they should pop open an encrypted image stored on their Cloud.
In the case of China, they should already be able to do that with impunity since they control the regional iCloud and keys
EDIT 2:
I'd also not be surprised if this was false however - I don't own a Huawei phone and I'm not located in China, so I can't verify this at all.
