Anthropic Tightens Claude Usage Restrictions: Mainland China and Hong Kong-Controlled Enterprises Also Barred From Using It Overseas

On November 11, Anthropic's official website indicates that the company's new "Supported Regions Policy" will officially take effect on November 12, clarifying that Claude.ai, Claude Code, Cowork, API, and Claude models provided via cloud platforms and authorized distributors are all subject to regional access restrictions.

Under the new rules, individuals in unsupported regions cannot use the relevant services; companies registered or headquartered in unsupported regions, as well as companies where individuals or entities in unsupported regions directly or indirectly hold a majority stake or control, are ineligible to use the services even if the relevant personnel are in supported regions.

At present, neither mainland China nor Hong Kong is listed on the supported regions roster. Anthropic stated that this update mainly serves to clarify the scope of application for existing regional restrictions.
