Environment
- Platform (select one):
- Claude CLI version: 1.0.35
- Operating System: Windows WSL（Ubuntu 22.04）
- AWS Region tested: cn-northwest-1 (Ningxia), ap-northeast-2 (Seoul)
Bug Description
When I invoke claude from my WSL Ubuntu in China (using Bedrock), I immediately get:
API Error: 400 Access to Anthropic models is not allowed from unsupported countries, regions, or territories.
Please refer to https://www.anthropic.com/supported-countries for more information.
However, if I launch an EC2 instance in ap-northeast-2 and run the exact same steps there, Claude works fine. Even on an EC2 in cn-northwest-1 it fails with the same unsupported‐region error. My understanding is that Bedrock’s Anthropic models should be reachable from China regions (via the public AWS endpoints).
Steps to reproduce
- In WSL Ubuntu 22.04 (or EC2 in cn-northwest-1):
a. Install Node/NPM & AWS CLI
b. aws configure (with valid credentials)
c. export CLAUDE_CODE_USE_BEDROCK=1
d. export AWS_REGION=cn-northwest-1
e. run claude, then type “Hello”
- Observe the 400 “unsupported country/region” error
- Repeat steps on an EC2 in ap-northeast-2 → no error, Claude responds normally.
Expected behavior
I should be able to call Claude via Bedrock in any AWS region—even cn-northwest-1—without hitting an “unsupported region” error.
Questions / Additional info
• Do I need to explicitly configure a proxy or custom endpoint for China regions?
• Is there a Bedrock-CLI setting in @anthropic/claude or the AWS SDK that I’m missing?
• Could this be a networking restriction from my local environment (China)…or something baked into the CLI?
