Thank you for post!
Microsoft Azure China is a separate cloud service operated by a local partner in China, 21Vianet, and is subject to Chinese regulations and compliance requirements.
I would suggest to refer to the Azure China documentation or contact Azure China support to check if there is any information available on OSCCA certification.
How ever please refer the below third-party document for more information
