Сон Сен
Sihanouk writes that in 1975 he, Khieu Samphan, and Khieu Thirith went to visit Zhou Enlai, who was gravely ill. Zhou warned them not to attempt to achieve communism in a single step, as China had attempted in the late 1950s with the Great Leap Forward. Khieu Samphan and Khieu Thirith "just smiled an incredulous and superior smile."" Khieu Samphan and Son Sen later boasted to Sihanouk that "we will be the first nation to create a completely communist society without wasting time on intermediate steps."
