America puts China on notice before trump-xi talks? DOJ probes suspected NVIDIA chip diversion

US authorities are scrutinising suspected efforts to divert advanced Nvidia AI chips to Chinese buyers in violation of export controls, while lawmakers from both parties push for tighter restrictions. The allegations have also fuelled concerns about overseas data centres being used to access restricted processors remotely. Beijing has rejected claims surrounding an alleged Chinese intelligence connection, while the company at the centre of the diversion suspicions has denied wrongdoing.
