Anthropic report alleges PRC AI labs misused user data via Claude; US-China law enforcement friction

Anthropic's September report documents alleged violations of PRC law by Chinese AI firms, including DeepSeek, Xiaomi, and Moonshot, which reportedly fed user-model conversations into Claude. The report raises concerns about data misuse and potential state-linked activity, but the claims are unverified and the firms have not responded. This adds to US-China tech tensions and could prompt regulatory or law-enforcement actions, though the immediate market impact is limited.
