The U.S. government has issued a sweeping global advisory urging technology firms and governments worldwide to avoid using Huawei's advanced AI chips, citing serious concerns over export control violations. The warning targets Huawei’s Ascend series—including the 910B, 910C, and 910D chips—which are believed to be manufactured or designed using American technology.

According to the U.S. Commerce Department, any entity using these chips could be in breach of export regulations unless they secure a special license—an authorization that is notoriously difficult to obtain. This move underscores Washington’s intensified effort to restrict China’s progress in high-performance computing and artificial intelligence.

The advisory arrives at a time when Huawei is positioning itself as a strong competitor to U.S. chip giant Nvidia, particularly in China's domestic market. Huawei has begun delivering AI computing clusters that it claims outperform Nvidia's offerings in both capability and energy efficiency.

U.S. officials are reportedly alarmed by the rapid expansion of Huawei’s chip deployments, especially in nations where American tech plays a significant role in infrastructure projects. The concerns have only grown amid increasing collaboration between Chinese tech firms and countries in the Middle East and Southeast Asia.

Further amplifying the tension, the U.S. recently walked back a key regulatory measure known as the Artificial Intelligence Diffusion Rule, citing delays and inefficiencies. Officials have promised a more robust replacement policy that will reinforce the nation’s export control strategy.

These latest developments make it clear: the U.S. is doubling down on its efforts to control the flow of advanced semiconductor technology and maintain its edge in the global AI race. Companies doing business with Huawei—knowingly or unknowingly—could soon find themselves in Washington’s crosshairs.
