The International Olympic Committee says up to 17 countries have expressed interest in hosting future Youth Olympic Games (YOG), including the United States and others from Africa and Latin America. The inaugural winter games will be held in Innsbruck, Austria in 2012 and the next summer games in Nanjing, China in 2014. Lillehammer, Norway, which hosted the 1994 Winter Olympics, is the only city which has expressed an interest in hosting the 2016 winter games, the IOC said, and has until November to submit a formal bid. The IOC's Olympic Games Executive Director Gilbert Felli said Saturday that an African and Latin American country as well as “some cities in the United States” have expressed interest in hosting the event in 2018 and beyond, but would not name them.
