Martin Urban, a member of the International Ice Hockey Federation competition committee, said the IIHF will continue to place countries in groups based on the ranking from the previous year's results.
There were a few media members inquiring about the possibility of establishing a world ranking for junior hockey based on results of the previous four years to present a more balanced WJC format.
Canada and Russia, which were in Group B of this year's tournament, played in the WJC final.
"The seeding is strictly written in the sport regulations to be fairly based on the result one year before," Urban said. "In junior hockey the teams are always quite different each year. That's why we have stuck to the current system."
The 2021 WJC setup in Edmonton and Red Deer, Alberta:
Group A (Edmonton) - Canada, Finland, Switzerland, Germany, Slovakia
Group B (Red Deer) - United States, Russia, Sweden, Czech Republic, Austria
