# Anthropic accuses Chinese labs of routing users to Claude for training data

Anthropic alleges Chinese labs fed sensitive data from armed forces and defense companies into its Claude model.

Anthropic alleged on Sept. 10 that some Chinese labs routed users to its Claude model to capture exchanges for training data, and that in some instances users from China's armed forces and defense companies entered sensitive surveillance data and weapons plans into the American model.[^1]

That came as Anthropic itself faces pressure from the U.S. government. The Commerce Department temporarily imposed export restrictions on its most advanced models, and the Defense Department sought to blacklist Anthropic as a supply-chain risk, a move a judge later ruled illegal.[^5]

The company also said this week that its Claude model participates in 26% of its research and development of new models and can complete most of a task from general instruction, under human supervision.[^7]
