A South Korean art troupe performed in the Democratic People's Republic of Korea earlier this week, as part of a friendly gesture between the two sides amid a diplomatic thaw. This comes after a DPRK delegation staged its own performances in the South, during the Winter Olympics in February. Shane Hahm has more on the reaction from Seoul.

SHANE HAHM SEOUL "A South Korean artistic delegation consisting of nearly a dozen musical acts, taekwondo athletes and their support staff are back home after performing for audiences in the DPRK capital of Pyongyang. It's the first time a South Korean act has performed across the DMZ since 2005. Audiences here have seen snippets of the concerts through news reports. But a local broadcaster that accompanied the group to Pyongyang is broadcasting an edited version nationwide tonight on tape delay. That's why I'm out here at Seoul Station to get a sense of how South Koreans are responding to this latest cross-border exchange."

CHOI JONG-SU SOUTH KOREAN RESIDENT "As someone from the same heritage, seeing the two sides interact was emotional and made me proud. I was very happy to see the good relations. It made me think we can do better in the future."

KIM HYUNG-HEE SOUTH KOREAN RESIDENT "Sure it was a big event on a national scale. But I feel like we may be getting too ahead of ourselves. I can't say I'm completely happy about it."

Over the past couple of years, there have been virtually no cross-border exchanges, diplomatically, economically, or on a humanitarian level. But we've seen an easing of ties this year with, of course, the show of unity at the PyeongChang Winter Olympics in February. Now all sights are set on a scheduled summit between South Korean President Moon Jae-in and DPRK leader Kim Jong Un on April 27 at Panmunjom.

Negotiations are on-going between working-level officials from both sides to discuss agenda items and other logistical matters in what will be the first inter-Korean summit in more than a decade.
