Israeli security firm Lava identified 32 Nvidia Blackwell Ultra B300 chips inside China Telecom’s network. These chips are subject to U.S. export bans and may only be sold to whitelisted buyers who promise not to re‑export them to sanctioned parties, including China. The presence of the chips raises questions about how they entered the Chinese data centre despite the controls.

## The facts

- 32 Blackwell Ultra B300 chips were found
- China Telecom is a state‑owned telecommunications provider

## Why it matters

It shows that export controls on high‑performance AI hardware can be bypassed, potentially giving Chinese firms access to advanced computing power.
