Anthropic Tightens Ban: Anyone in China or Controlled by Chinese Capital Is Barred from Using Claude

Anthropic updated its Supported Regions Policy on November 10, effective November 12, tightening access to Claude.ai, Claude Code, Cowork, its API and developer platform, and Claude models delivered through cloud providers and authorized resellers. The new rules bar individuals located in unsupported regions, entities registered or headquartered there, and any entity directly or indirectly majority-owned or controlled by such individuals or entities—regardless of where those users or staff are located. Mainland China, Hong Kong, Macau and Russia are absent from the supported-regions list, meaning Chinese users and China-controlled firms lose access even when operating elsewhere. The change matters because it extends restrictions from geography to ownership, potentially cutting off a broad set of Asia-based developers and enterprises that build on Claude through the API or cloud partners. What to watch next is how affected teams migrate workloads to alternative models and whether cloud resellers clarify enforcement for entities with mixed ownership.
