Jedidiah @Jammana In my own opinion the Host should study first the do's and dont's of having this kind of events. Remember this event has so many countries will attend and participate which the Host should also think what's other countries field of interest. They should be open-minded in terms of there rules and regulation by not only thinking of one countries interest.
