from what I heard , Iran has registered to participate in Alpine, CC skiing, SkiMo, Skating (they didn't mention which discipline ) and ... (this one will be surprising ) ... Curling
Curling is not a sure thing yet, the NOC has to approve it. the team is very new. I mean very very new, only few months ago they gathered few people to start the sport you can't lose 100-0 in Curling, right ?
anyway it will be first time ever Iran participating outside of FIS disciplines. ( I didn't count Ski orienteering in 2011 which was the same as CC)
nobody cares about winter sports here. therefore finishing last won't have consequences. they can afford sending very weak teams. (which is not the case for the main Asian Games)
