From Massline.info: This is the complete version of the important English-language pamphlet published by the Foreign Languages Press in Peking (now Beijing) in 1968. The PKI self-criticism included in this pamphlet was co-authored by Sudisman, who led the Political Bureau after the murder of the Aidit by the Army during the 1965 massacres. Apparently the full document (which is not included in the pamphlet from China) specifically blames Aidit for the revisionist road after 1951 and the resulting catastrophe. But the ideological thrust of the self-criticism is against the so-called Bandung theses, a revisionist line that led to uncritical support of Sukarno among other things. Sudisman himself was arrested by the fascist regime in December 1966, put through a show-trial in 1967-68, and sentenced to death. This PKI self-criticism was publicized internationally, especially by another Political Bureau member, Jusuf Adjitorop, who was based in Beijing after 1965. (He was in China when the 1965 massacre occurred.) Adjitorop may have co-authored the self-criticism.
