AWS Transit Gateway now supports the ability to establish peering connections between Transit Gateways in AWS China (Beijing) Region, operated by Sinnet and AWS China (Ningxia) Region, operated by NWCD. Transit Gateway is a service that enables customers to connect thousands of Amazon Virtual Private Clouds (Amazon VPCs) and their on-premises networks using a single gateway. With AWS Transit Gateway, customers only have to create and manage a single connection from a central regional gateway to each Amazon VPC, on premises data center, or remote office across their networks. 

The ability to peer Transit Gateways between different AWS China Regions enables customers to extend this connectivity and build networks spanning multiple AWS China Regions. Traffic using inter-region Transit Gateway peering always stays on the AWS network and never traverses the public internet, thereby reducing threat vectors, such as common exploits and DDoS attacks. Inter-region Transit Gateway peering encrypts inter-region traffic with no single point of failure.
