The U.S. Defense Department has added dozens of Chinese companies, including games and technology company Tencent, artificial intelligence firm SenseTime and the world’s biggest battery maker CATL, to a list of companies it says have ties to China’s military.

In recent years, Washington has sought to restrict sharing of advanced technology, including semiconductors and AI, deeming it to be a threat to national security.

The U.S. Defense Department updates its list of “Chinese Military Companies,” or CMC list, annually. With the latest revision, it includes 134 companies. The National Defense Authorization Act of 2024 bans the Defense Department from dealing with the designated companies beginning in June 2026.
