Is it possible the Newsweek list is wrong?
The EO and Annexes are not on the Federal Register website yet but on the Whitehouse website it has EO[1] and Annex I[2] and Annex II[3].
I do not see Russia or Ukraine mentioned in any of those so I would assume both get the base "10 percent" under section 2/3.
