China's industry regulator has flagged a potential 'backdoor' risk in Anthropic's Claude Code, with some reports suggesting the issue may be related to a hidden china-detection feature. The nature and implications of the alleged backdoor are unclear, with some outlets framing it as a security concern and others implying it may be a point of contention between companies. The situation has reportedly led to some entities, such as Alibaba, taking action to restrict use of the Claude Code.
