Chinese tech giant Alibaba is barring its employees from using Anthropic's Claude Code, an AI-powered coding assistant, starting July 10. According to reports aggregated by NewsCord, finance.biggo.com, incrypted and The Tech Buzz, the company is imposing a full ban and moving its developers onto an in-house tool instead.
The move is being framed largely around security. The Tech Buzz reports that Alibaba is acting over security fears, and the shift lands alongside a separate technical concern: Let's Data Science reports that Claude Code has flagged a potential "session leakage" issue, a term that broadly refers to data or context from one user session being exposed where it shouldn't be.
The timing also coincides with tighter controls from Anthropic itself. According to the Financial Times, as reported by Moneycontrol, Anthropic is cracking down on Chinese firms that have been accessing its Claude AI through overseas workarounds designed to get around access restrictions.
Taken together, the sources point to two forces pushing in the same direction: a major Chinese customer walking away from a leading American AI coding tool, and the American developer tightening who can use its models from China. The reporting does not detail the full technical scope of the session-leakage concern or the specific workarounds Anthropic is targeting.
Why it matters: the episode shows how AI coding tools are becoming both a security question and a geopolitical fault line, with companies increasingly choosing home-grown alternatives over cross-border reliance.
