Gamelift server inside mainland China, not HongKong

To have Amazon GameLift fleet locations inside mainland China, you need to work with AWS's China regions, which are operated by local partners. Specifically, you would need to use either the China (Beijing) Region, operated by Sinnet, or the China (Ningxia) Region, operated by NWCD.

Here are the key points you should know:

1. Separate Account Required: You must have a separate AWS (China) account to use Amazon GameLift in mainland China. Your regular AWS account won't work for these regions.

2. Limited Features: Some Amazon GameLift features are unavailable in the China Regions. Notably, multi-location fleets are not supported in China Regions.

3. Regional Isolation: Amazon GameLift resources that reside in China Regions cannot interact with or be used by resources in other Amazon GameLift Regions. This means your China deployment would be isolated from any GameLift resources you have in other global AWS regions.

4. Integration: Yes, when you set up your AWS (China) account through the partner (Sinnet or NWCD), you will have access to Amazon GameLift services in those regions. The service integrates normally within the China regions, but operates independently from your global AWS infrastructure.

To proceed, you would need to establish an AWS (China) account through one of the authorized partners and then create your GameLift fleets in the Beijing or Ningxia regions.
