The article formulates and analyses a hypothesis, according to which, thanks to modern postmodern art, a single international visual language was formed in the late 20th – early 21st centuries, and previously mysterious and incomprehensible foundations of national culture became accessible and open at the international level. This concept is considered on the basis of the international popularization of Chinese art, as the Chinese national culture and art remained mysterious for Western audiences for many centuries.
