South Korea will hold a ceremony later this week to mark the one-year anniversary of the historic first summit between President Moon Jae-in and North Korean leader Kim Jong Un.

There's just one catch: North Korea's attendance is uncertain.

The Unification Ministry in Seoul said in a statement late Sunday that the event — called "The Long Road" — is scheduled to feature artists from South Korea, the U.S., China and Japan and will be held Saturday at the border village of Panmunjom.
