The competitions were originally scheduled to be played in Tyumen, Russia on February 15 and 16.
The International Federation of Associated Wrestling Styles (FILA) decided to postpone this event, because it coincided with the Sochi 2014 Winter Olympics.
The Iranian wrestling officials submitted a bid to host the competitions.
FILA president Nenad Lalovic has accepted to change the place of the event and it will be held at the Azadi 12,000 seat Stadium in Tehran, Iran on May 15-16.
