AWS Transit Gateway now supports the ability to establish peering connections between Transit Gateways in both AWS GovCloud (US) Regions. 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 Regions enables customers to extend this connectivity and build global networks spanning multiple AWS Regions. Traffic using inter-region Transit Gateway peering is always encrypted and stays on the AWS global network. For more information, see the AWS Transit Gateway product page and documentation.
