The group classification for the Olympic qualification tournaments is a disaster for the European teams, except for Russia. They can book their tickets to Tokyo in every situation.
I took the World Cup 2015, Olympic Games 2016 and the World Championships 2018 into account. There is some confusion if the VNL 2018 will count for the World Rankings.
These will be the groups when the VNL doesn't count for the World Rankings (likely): A: SERBIA (1), TURKEY (12), CAMEROON (13), BELGIUM (24)
B: CHINA (2), PUERTO RICO (11), GERMANY (14), TRINIDAD (23)
C: USA (3), DOMINICAN REPUBLIC (10), BULGARIA (15), KAZACHSTAN (22)
D: RUSSIA (4), ARGENTINA (9), THAILAND (16), CUBA (21)
E: BRAZIL (5), KOREA (8), KENYA (17), CANADA (20)
F: NETHERLANDS (6), ITALY (7), MEXICO (18), AZERBAIJAN (19)

Horrible for especially Netherlands. Finishing 4th at both the OG as the WCH and then placed in a group with Italy ...
