This has been seen elsewhere too and contacting someone at chinanet has been difficult. Your DNS may be filtered if it supports recursive lookups from chinanet. Forgetting for a moment the potential problems with doing that, its been suggested that chinanet is filtering DNS as a means to prevent their users from pointing at your DNS to get to sites that they may deem inappropriate (censorship).
Does anyone know of any good contacts at China Telecom, or know if there's some explanation for this?
This is a problem. If you have someone on staff that can speak Chinese, that might be useful. I haven't heard of email to the public addresses resulting in any meaningful response. I can't point to a specific contact at the moment, but I have been peripherally involved in this problem and if something definitively useful comes out of it I can follow up with you in private email.
