BEIJING: Nvidia CEO Jensen Huang called China's open-source artificial intelligence a "catalyst for global progress" and hailed the country's innovation in the sector as he addressed an expo in Beijing on Wednesday (Jul 16).

The approvals mark a major reversal after April’s sweeping restrictions, imposed by the Trump administration, barred companies from selling certain advanced semiconductors to China. Those rules left Nvidia facing a $4.5 billion inventory write-down, as it had no alternative buyers for its H20 chips.
