Groups E-H are playing in Athens; it is Hungary who have the top seed in group E after finishing fifth last year. Denmark and Norway join them as well as South American silver medallists Argentina.
Sweden narrowly missed out on a medal last year, and they will strive for a better outcome in this competition. Slovenia are also in the group, and the two will play Greenland and Bahrain in the Ano Liosia Olympic Hall.
Group G features bronze medallists Serbia. Iceland will be part of the group as well, and South American bronze medallists Chile and Morocco have tall tasks ahead of them with these two in the group.
In group H perennial African powerhouse Egypt are the top seed, but they will have to contend with playing a Greek team who have home advantage. NorCa champion Cuba and Asian semi-finalists Saudi Arabia complete the group.
After the end of preliminary play, the top two teams in each group will advance to the main round, while the bottom two will play in the President’s Cup. The two host nations will split both events. When all matches in the main round are completed, the top half of each of the four groups go to Berlin to play in the quarterfinals on 29 June, followed by the medal round on 1 and 2 July.
