Will apple intelligence work with Chinese Apple ID and US bought iPhone?

Hi, I’m trying to set up Apple Intelligence on my iPhone 16, but nothing happens when I click “Set Up Now.” My device was purchased in the U.S., and I’m currently in the U.S., but I’m using a China mainland Apple ID.

I found on the Apple Support website that Apple Intelligence is not currently supported for China mainland Apple IDs. How to get Apple Intelligence - Apple Support

Will support for China mainland Apple IDs be added in future updates? If so, will Apple Intelligence use ChatGPT or a Chinese AI model in that case?
