The US Commerce Department has issued new guidance to close a loophole that permitted the export of advanced AI chips, including Nvidia's Blackwell processors, to overseas subsidiaries of Chinese firms without requiring a license. This move comes in response to concerns about national security and the potential for these chips to be used in ways that could benefit Chinese technology development. Previously, the AI Diffusion rule, which mandated licenses for such exports, was not enforced, leading to fears that hundreds of thousands of chips may have been exported to Chinese entities. Chris McGuire, a former State Department official, emphasized the seriousness of the loophole, stating that it allowed Chinese companies to acquire these chips legally and at scale. He also pointed out that another loophole remains unaddressed, which does not require TSMC to conduct enhanced due diligence on AI chip orders, indicating that further regulatory action may be necessary.
