 == Qualified teams == 

 I think Russia qualifies because 1) it scored 12 points and 28 * 3 / 7 = 12 (number_of_all_games * three points if win / number_of_teams) and 2) there will be games United States vs. Latvia; Belarus vs. Germany; Latvia vs. Belarus and Germany vs. United States — so I'm not sure that all four teams (Belarus, USA, Germany and Latvia) scores 12 points in 4 games for each team and overtake Russia.
