Group One features 12 teams, 11 of which competed at the same level in 2016 - Argentina, Belgium, Brazil, Bulgaria, France, Iran, Italy, Poland, Russia, Serbia and the United States.

They will be joined by last year’s Group Two winners Canada.

The 2017 Group One finals are due to take place in Brazilian city Curitiba from July 4 to 8.

Group Two also feature 12 teams, 10 of which were ranked 14th to 23rd in the 2016 edition - China, Czech Republic, Egypt, Finland, Japan, The Netherlands, Portugal, Slovakia, South Korea and Turkey.

They have been joined by last year’s Group Three winners Slovenia and Australia, who finished 12th in Group One in 2016.

The Group Two finals are set to be held in Gold Coast in Australia on June 24 and 25.

Group Three similarly features 12 teams with Chinese Taipei, Germany, Greece, Kazakhstan, Mexico, Montenegro, Qatar, Spain, Tunisia and Venezuela joined by Austria and Estonia.

The Group Three preliminary round will be played over two weekends in four-team pools.
