The north and south have used culture and sport as a gesture of reconciliation before: during the Sunshine Policy period from 1998 to 2008. But let's start with the plans for this year's games in PyeongChang. 

Among the delegation sent by Pyongyang to the Pyeongchang Olympics, the art troupe Moranbong is expected to be a great sensation. Founded by Kim Jong Un in 2012, the all-female band features western music and outfits. At one of their first performances in 2013, the band played to a backdrop of Snow White, as well as other Disney characters. This will be their first performance in South Korea.

Another highlight of the delegation is the cheerleader group. They are no stranger to the public in the South. They made a big impression when 300 of them made their first appearance at the Asian Games in Busan in 2002. In 2005, Kim Jong Un's future wife Ri Sol-Ju was among the group who attended the Asian Athletics Championships in Incheon. Another cheerleader was Cho Myung Ae, whose good looks won her a huge following in the South. She appeared in a television commercial with South Korean pop star Lee Hyo-ri. The theme song of the commercial "there will be one day" became a big hit on the Internet.

This year's Winter Games in Pyeongchang will be the cheerleaders' fourth visit to the South. And that's not the only way that sporting events have been used for reconciliation. The two Olympic teams marched behind the unification flag at the opening ceremonies of the 2000 Olympics in Sidney, the 2004 Summer Games in Athens, and the 2006 Winter Games in Torino.
