The US Department of Defense has updated its list of companies believed to be aiding China's military, including major players like Alibaba, Baidu, and BYD. This move, which follows a recent meeting between US and Chinese leaders, reflects growing security concerns amid escalating geopolitical tensions. The list, known as the 1260H or CMC list, now includes various technology firms crucial to enhancing China's military capabilities. Notably, companies such as WuXi AppTec and robotics firms like Unitree are also on the list. While the Pentagon asserts these companies qualify as 'Chinese military companies,' the firms have vehemently denied any military ties and plan to contest their designations. The updated list does not impose immediate sanctions but will restrict US defense contracts with these firms starting this month and prevent purchases from them via third parties by 2027. The Chinese embassy in Washington condemned the list, calling for a fair environment for Chinese companies, while US lawmakers view the list as a warning regarding national security.
