The Pentagon briefly posted a similar expanded list in February, then withdrew it without explanation before Trump's China trip.

The Pentagon's updated 1260H list now names 188 Chinese companies it says support the military, including Alibaba, Baidu, BYD, Unitree, Nio, and CXMT.

Alibaba, Baidu, and BYD were on the list of companies believed to be aiding the Chinese military and operating in the U.S.

US-China relations: Pentagon's update on Monday comes months after it briefly released -- then withdrew -- an earlier version of the list without explanation.
