Alibaba Bans Employees from Using Anthropic's Claude Code Over Security Concerns

Jul 3, 2026

Alibaba Group Holding bans its employees from using Anthropic's Claude Code starting July 10, 2026, citing security risks from embedded backdoors that track Chinese users. The decision reverses a policy allowing up to $1,400 in monthly reimbursements for external AI tools, directing staff to use its Qoder platform instead. This follows Anthropic's accusations that Alibaba-affiliated accounts conducted a massive model distillation campaign, highlighting growing US-China AI fragmentation.
