Thai khon drama, or the ‘masked dance’ drama, is now listed as an ‘intangible heritage of humanity’ by UNESSCO. On the ceremony yesterday, UNESCO also listed Cambodia’s khon drama as an intangible heritage of humanity. Reacting to UNESCO’s decision, Thai PM Prayut Chan-o-cha posted in his Facebook page that he was pleased with the decision and he credited this achievement to Her Majesty Queen Sirikit for her contributions to preserve and promote this traditional art form.
