Great firewall of China & AWS China?

We have a need to solve the AWS & China problem. Namely, China has a habit of seemingly randomly blocking all or most AWS traffic.

We are investigating setting up a Chinese company in order to satisfy their laws, and starting to figure out the high level technical details around manageably replicating our infra into an AWS China account (they are a completely different entity to AWS as we know it, but offers a large % of the same services).

Have you had any dealings yet with convox within the AWS China region(s)?
