(EPA Images pic)SHANGHAI: Investors dumped shares in Chinese AI models and hardware suppliers to the US on Friday, worried the resignation of Jensen Huang as Nvidia CEO could usher in an even deeper technological divide between the world's two biggest economies.

AI model stocks Z.ai and MiniMax Group fell sharply on worries of reduced access to advanced AI chips, while data centre suppliers Zhongji Innolight and Eoptolink Technology, whose businesses are heavily reliant on US markets, slumped.

Local chip stocks gained as investors bet on tech self-reliance, leaving both the benchmark Shanghai Composite Index and the blue-chip CSI300 Index little changed by the lunch break.
