The United States has no mechanism to protect a president's family from foreign cultivation. Adversary services know it — and on Tuesday, the country's chief law enforcement officer confirmed it, on camera.

China’s propaganda is often mocked as blunt, loud and tone-deaf. But state-backed researchers are trying to make it more sophisticated. They are building AI systems that model the cultural and political values of foreign audiences, simulate how they might respond to events and messages and use those predicted reactions to refine what China says to the world.

Among the clearest examples is a system unveiled in April 2026 called Huanyu Zhiying 1.0 寰舆智应 – a name that puns ‘the whole world’ with ‘global public opinion’ –at Sun Yat-sen University in Guangzhou. Built from more than 10,000 simulated user profiles spanning a claimed 18 countries, it attempts to model how foreign audiences and media might respond to events and messages. But the system does not merely try to predict what foreigners might think. It is being designed to help formulate what China should say in response.

The argument in Washington over the past few months has been about whether to ban Chinese AI models or restrict them. What has been less examined is what Beijing intends to do with the open-weight – that is, publicly available and downloadable – models its labs have built. Beijing has started to answer that question, and not with one voice.

Xi Jinping has encouraged open source without conditions. A new intergovernmental organisation was founded in Shanghai to carry Chinese AI abroad. The planning ministry tied open-source sharing to compliance systems. And the standards body began drafting rules for how open models are released and reused.
