Anthropic Tightens the Claude Gate for Chinese Engineers
Anthropic is tightening rules to block mainland China access to its Claude AI, closing loopholes used by Ant Financial (corporate Claude accounts via intranet) and ByteDance (engineers using VPNs), and by Microsoft through Singapore entities. It’s also pursuing transfer-station bans to prevent routed requests. Larger Chinese AI groups avoid these workarounds due to data concerns. Anthropic says access in unsupported regions is prohibited and relies on evolving detection to ban violators.
