North Korea has started to promote an arts festival featuring international participants for next spring in Pyongyang, a move that one expert said raises the possibility of a wider reopening to tourism around the event.

The 33rd biennial April Spring Friendship Art Festival will be held from April 11-25 and will include “famous artists of authoritative art, acrobatic and dance troupes… promoting friendship, unity exchanges and cooperation among men of culture and artistes from different countries of the world,” according to the DPRK Ministry of Culture’s website.
