According to Wikipedia:
The Bamboo Curtain was the east Asian version of the Iron Curtain. It marked the border between the communist states of East Asia, especially the People’s Republic of China during the Cold War, but excluding the eastern Soviet Union . . . The term “Bamboo Curtain” was used less often than the term “Iron Curtain” in part because while the latter remained relatively static for over 40 years, the former shifted constantly.
Today we are encountering a new Marxist strategy that I call the “Bamboo Shower Curtain.”
