I'm a bit reluctant to merge this until we have the data available. It will just create confusion for people who expect to see the data but instead won't get anything.

@cristim agreed

cfn-lint started picking up EC2/RDS/DAX instance type information from pricing for AWS China regions this month: https://github.com/aws-cloudformation/cfn-python-lint/pull/1635#discussion_r471975612 so I think it's worth reconsidering this now

@PatMyron do you happen to know the latest on this? I think it would be cool to add pricing for China and can merge this in.
