Huawei has been blacklisted for trade in the United States. The impact is that Google announced they will cease to provide Huawei phones with security & Android updates, and the phones will not be shipped with Google Play Services.
You might still be able to receive updates if Huawei launch their own OTA update system, but switching to that means that all your Google Play Services apps (including the play store) will likely cease to work. You could potentially side-load the play store, but it will be interesting to see if there are any certification issues with play Store access under such circumstances.
China hasn't really killed people left right and center - they've imprisoned them. If anything, they've only killed people in their own country so you could say they've killed people in the center.
USA, on the other hand, has killed people left right and center - they killed people in Iraq, Afghanistan, Pakistan, Libya, Syria, Yemen. Left right and center!
