[Question] Is AWS China supported?

[kwakiutlCS]

I'm trying to deploy to a S3 in AWS China, but I'm in doubt if it is not supported or I am doing something wrong.

I'm receiving the error
com.amazonaws.services.s3.model.AmazonS3Exception: The provided token is malformed or otherwise invalid.

As far as I can see all the attempts try to connect to an US-EAST-1 endpoint
"Connection released: .[...] ->https://[bucket-name].s3.amazonaws.com:443] [...]"

I'm using version 1.3.3, with IRSA, but also tried with 1.3.2, with different authentications before

thank you for your help
