A US federal judge has ordered the Department of Defense to shield Alibaba Group Holding Ltd. from a law while she considers whether the measure is constitutional, according to Kate O'Keeffe reporting for Bloomberg.

The reprieve matters because of what the law had already done. According to the Bloomberg report, the measure prompted all of Alibaba's lobbyists to drop the Chinese e-commerce giant as a client. The judge's order gives the company a temporary shield from the law's effects while the underlying legal question — whether the measure passes constitutional muster — remains unresolved.

The dispute lands against a backdrop of heightened US-China friction over technology and artificial intelligence, an area where American policymakers have increasingly moved to restrict or scrutinize Chinese firms. That tension is part of why a court fight over how one such law applies to a company the size of Alibaba draws attention.

The available reporting does not specify the full details of the law, the court, or the timeline for the judge's ruling on constitutionality. What is clear is that, for now, the Pentagon has been directed to hold off on applying the measure to Alibaba.

Why it matters: The case tests how far US national-security and technology laws can reach into the operations of major Chinese companies — and whether those laws will survive constitutional challenge — at a moment when Washington and Beijing are jockeying over the future of AI.
