> Why aren't they being prohibited from using other Chinese consumer electronics, like Lenovo, Xiaomi, etc?

I suppose it depends which "approved devices" list you're using. If I look at the US Department of Defense's approved products list I see Korean brands like LG and Samsung but I don't see Lenovo or Xiaomi:

I've done some consulting for a company fulfilling a defense contract and they had to switch their entire desktop anti-virus solution because they were using foreign made software and DISA was not happy about it. The origin of hardware/software is very much a concern for the US gov't.
