Under Kim Il Sung's rule, Kim Il Sung had sent delegations into African countries to express solidarity as seen through certain documentaries that were produced within the DPRK. For what I know however, this type of solidarity was taking place somewhere in the 1980's, I'm unsure as to what documentary showed this. But it went into depth about the DPRK's delegations teaching African students about the DPRK's society and its goals. If I remember, it wasn't Zimbabwe though.
