Actually these was a Maoist current in the ANC in the early 1960s, and not: "During the Sino-Soviet conflict of the 1960s and ‘70s, it supported the Pan Africanist Congress (PAC) - only - over the Russian-backed ANC" (sic). See Stephen Ellis´s: EXTERNAL MISSION: The ANC in Exile 1960-90 (2012):  pps. 7, 8, 10, 12-3, 28-9, 35, 53-4, 57, 84, 92, 100, 103, 109, 115. Two names are important here:  Rowley Arendstein and Vella Pillay, while Harry Gwala, from the KZN Midlands, was an important warlord and militarist who followed the "Chinese Line". Jacob Zuma was Gwala´s protege and homeboy. Yes, the MAIN ANC support came from the ex-Soviet Union and its satellite countries in East Europe, including Cuba.  Sweden did NOT provide arms or military training but political support and was a conduit for funds from EU/US sources.  All these fantasies about "Commies for Afrika" is just a load of bull. Read Ellis instead.
