Comment 1 Alex Crawford 2019-01-05 00:40:33 UTC 
AWS China isn't supported. We can remove the option from the installer.
Comment 2 W. Trevor King 2019-01-06 05:13:54 UTC 
There's some WIP in [1], but we may hold off until we have a more reliable approach based on RHCOS build metadata.  For installer releases, which pin to a single RHCOS build, the simple approach is fine and I'm taking that route for v0.9.0 [2].

Comment 3 W. Trevor King 2019-01-24 08:49:46 UTC 
I think comment #2 is sufficient for closing this bug, now that we have a few releases under our belt with that approach.  The only way folks could hit the cn-north-1 issue would be if they manually configured that region in their install-config.

The above paragraph assumes this issue is "installer's region select widget lists unsupported regions".  If the intention was to add support for cn-north-1, that would be an issue with the RHCOS component, not an installer issue.
