The CPC has ‘repressed’ Mao’s writings – or so the myth would have us believe. I am never quite sure whether this sort of observation is an article of unquestioned faith, myth, or simply a ‘fact’ that is believed by many due to thousands of repetitions. To wit, since some of Mao’s texts are too explosive, they have – so some believe – been hidden by a CPC keen to keep a lid on how Mao is studied and interpreted. Indeed, if you want a full collection of Mao’s writings you have to go to the series published in Japan, called Maozedong ji.
There is one small problem: you can easily get all of Mao’s material and more in China. For example, this website has pretty much everything. In this collection, have just discovered a wonderful 700 page manuscript, concerning Mao’s study notes and talks about Stalin’s study of economic problems under socialism, as well as material concerning political economy in the Soviet Union and China.
