US AI rivals push for model export curbs, deepening China AI stock selloff

China AI Stocks’ Pain Grows as US Rivals Push for Model Curbs

Anthropic and Google are lobbying the US government to add AI model weights to export controls targeting China. If adopted, Chinese firms would face tighter access to frontier models like Claude and Gemini. The news deepened a selloff in China AI stocks—SenseTime and Baidu fell further, with the Hang Seng Tech Index now down over 20% from its 2026 high. The post doesn't spell out a timeline or likelihood for the proposal; it's still at the lobbying stage, but markets are already pricing in the risk.

Why it matters: Anthropic and Google pushing for model weight export controls is a concrete policy signal with direct market impact. Bloomberg exclusive, strong sourcing. Deduction: the article doesn't give the proposal's specific progress or timeline — still at the lobbying stage.
