On North side of DMZ, it's change in the air

Lt Col Hwang Myong Jin has been a guide on the northern side of the Demilitarized Zone that divides the two Koreas for five years.

He says that since the summits between North Korean leader Kim Jong Un and the presidents of South Korea and the United States, things have quieted down noticeably in perhaps the last place on Earth where the Cold War still burns hot.

"A lot of things have changed. Listen to how quiet it is," he said as he stood on the balcony of a large building overlooking the blue and white barracks and concrete demarcation line that mark the boundary between North and South.

"The South used to blast psychological warfare propaganda at us," he said. "But since the summits, they have stopped. Now there is a peaceful atmosphere here."
"It's not that we want tourists to come, but people want to see," he said. "There are dangers."
