With both nations upbeat after recent bilateral talks, and sports diplomacy surrounding the Winter Olympics, North Korea has issued a very unusual statement of unity addressed not to South Korea, but to all Koreans across the world.

North Korea called for all Koreans "at home and abroad" to work together on a breakthrough toward unification of the Korean Peninsula, saying it should be done without the help of other countries.

The statement urged a push for bilateral cooperation, and to encourage increased contact and travel between the Koreas. That's a particularly surprising call, as generally North Korea does not allow its citizens to travel abroad for fear of defection.
