China Snubs US Congress AI Visit, Revealing New Tech Caution

Analysts say this "cold shoulder" denied American officials a rare look inside one of the world’s fastest-moving artificial intelligence (AI) industries. The snub highlights Beijing’s increasingly selective approach to AI diplomacy. It also reveals a paradox: while the US and China continue to talk about AI safety, the channels that once helped them understand each other are closing.
