The Pentagon has recently expanded its list of Chinese firms believed to be assisting the Chinese military, with new additions including Alibaba Group (NYSE:BABA), Baidu Inc.

(NASDAQ:BIDU) and BYD (OTC:BYDDY).

The Defense Department on Monday updated its "1260H list," adding companies it suspects have ties to China's military or defense-industrial sector.

While the new additions do not prompt immediate sanctions, they do prevent the Department from contracting directly with these companies starting later this month.

Moreover, the Pentagon will be prohibited from procuring its products or services through third parties starting June 2027.
