"We are sure already that this will be a spectacular event," Joel Delplanque, the International Handball Federation (IHF) first vice-president and IHF representative at Kazan 2018, said.
"Kazan is the sports capital of Russia and is well-known everywhere, and we have spoken with everyone on the Organising Committee in detail and they are ready.
"Kazan 2018 will be a new step for the IHF with 16 teams in both the men’s and women’s competitions - 32 in total.
"New countries like Greece, France, Mexico, Paraguay, New Zealand and Vietnam - it really is a worldwide event.
"We are working hard with the International Olympic Committee to include beach handball inside the Olympic programme.
"Of course, beach handball will be in the Olympic programme next October with the Youth Olympic Games taking place in Buenos Aires, Argentina.
"Beach handball will also be on the programme for the ANOC (Association of National Olympic Committees) World Beach Games in San Diego, USA next year and were also preparing a showcase event during the Tokyo 2020 Olympic Games.
"So Kazan is not only a great sporting event, but a political event too.
"Thank you to the Organising Committee for preparing everything and we are sure everything will run in the right way."
