It’s the Joint Dictatorship of the Proletariat of Oppressed Nations.

I think it’s another way of saying “Global South” that’s oppressed and exploited by colonalism imperalism. Don’t know if that’s accurate enough.

Joint-dictatorship of the proletariat of oppressed nations

Also fundamental to Maoism–Third Worldism is an understanding of the joint-dictatorship of the proletariat of oppressed nations (JDPON) and/or global new democratic revolution (GNDR) which is proposed as a form of alter-globalization aimed at breaking the political and economic foundations of the economic parasitism between the First and Third Worlds. The JDPON is a point of relative contention between the various proponents of Maoism–Third Worldism or at least the tendencies which have now been named as falling generally under the Third Worldist tendency within Marxism. It is upheld by a variety of Leftist parties, including Revolutionary Anti-Imperialist Movement and Maoist Internationalist Movement (Prisons).

Before Maoism, a similar theory was proposed by Mirsaid Sultan-Galiev, who argued for a Colonial International, that would exist independent of, or if necessary, in opposition to the Third International. Galiev stated that a Colonial International would consist of all oppressed nations in Africa, Asia and both South and North America, arguing that the native populations as well as the African populations of the Americas were colonised nations. Galiev argued that this International could possibly need to form a dictatorship over the metropolitan states of America and Europe.
