READ MORE As XDA Developers points out, the US's National Defense Authorization Act (NDAA) classifies "Communist Chinese military companies" as "any person identified in the Defense Intelligence Agency publication numbered VP-1920-271-90, dated September 1990, or PC-1921-57-95, dated October 1995, and any update of those publications for the purposes of this section" along with "any other person that–(i) is owned or controlled by the People’s Liberation Army; and (ii) is engaged in providing commercial services, manufacturing, producing, or exporting". The US hasn't elaborated any further on how Xiaomi - a company which specialises in consumer electronics - fits into this, or what evidence they have to back this up.
