The Biden administration added 16 entities to its restricted trade list on Wednesday, including a Chinese company whose TSMC-made chip was illegally incorporated into a Huawei artificial intelligence processor.

The US Commerce Department added 25 companies based in China, as well as two in Singapore, to its Entity List. Being placed on this list means that these companies can no longer receive US goods or technology without a special license,

The moves are part of the Biden administration’s last-gasp efforts to clamp down on China’s harnessing of AI for its military and tech sector.

The Biden administration added more than two dozen Chinese entities to a U.S. restricted trade list on Wednesday, including Zhipu AI, a developer of large language models, and Sophgo, a company whose TSMC-made chip was illegally incorporated into a Huawei artificial intelligence processor.
