Nanjing, capital city of East China's Jiangsu Province, will host the second edition of the summer Youth Olympic Games, the International Olympic Committee (IOC) said Thursday.

Nanjing received 47 votes to edge out runner-up Poznan, Poland, which received 42 votes.

Some 3,600 athletes ranging in ages from 15 to 18 are expected to compete in Nanjing, which will feature 26 different events.

Nanjing became the first Youth Olympic Games host city directly elected in an IOC Session, given previous hosts Singapore (2010 summer Games) and Innsbruck (2012 winter Games) were selected via postal vote.

The IOC established the Youth Olympic Games in an effort to shore up dwindling support for the Games among younger people and to fight obesity among teenagers.
