A big group of South Koreans sat through a very North Korean-style celebration on Friday night in Pyongyang, the North Korean Mass Games at May Day Stadium. It's part of an attempt to bring the two Koreas closer together, and this time the opportunity was the anniversary of a previous summit between past leaders of both Koreas. Back in October 2007, North and South Korea held their second leaders' summit, between Kim Jong Il and Roh Moo-hyun. It took seven years to get to that point after the first leaders' summit in 2000. And it has taken another 11 years to get the leaders of North and South Korea to sit down together again, now in 2018 - which they have done three times this year.
