This question piqued my interest, so I went to see if the official Czechoslovak Communist newspaper Rudé právo had anything to say about Jonestown. In short: Rudé právo wrote about both Jim Jones and his followers in mostly negative terms, continually referring to the members of the People's Temple as "religious fanatics." They did not describe them as possible comrades, but as misguided victims looking for an escape from a cruel capitalist system. The most specific reference I could find to the group's political orientation was one line where Jones was described as having "participated in the Maoist movement." (The Czechoslovak regime was no fan of Mao, naturally.)

There was no coverage of the People's Temple or Jonestown until after the massacre. On November 21, it published an article titled "Mass suicide of religious fanatics". It provided the basic facts of Congressman Ryan's visit to Guyana and the subsequent mass murder/suicide, but also connected it to the murder of Sharon Tate, editorializing that young Americans were joining fanatical cults en masse as an escape from the alienating American way of life, characterized by the mindless pursuit of material gain. In articles over the following days, it emphasized the US government's responsibility for Jonestown: one article explained that Walter Mondale and other leading US political figures had assisted the People's Temple diplomatically in their relocation to South America, others said that the State Department had been informed of the conditions at Jonestown and preparations for the massacre and chose not to intervene, others speculated that the assassinations of George Moscone and Harvey Milk might be related to the People's Temple and reported allegations, evidently being investigated by the FBI, that they had an assassination squad that planned to kill Jimmy Carter and kept millions of dollars in a Swiss bank account.

On December 12, it published photographs from the massacre, describing the dead at Jonestown as "victims of a social system characterized by racism and its extreme, the Ku Klux Klan, characterized by drug abuse, corruption and all-powerful gangsterism, a system of man's hatred toward man," and seekers of economic, social, and racial justice who "sought an impossible and utopian solution, and became victims of a murderer." This was accompanied by a picture of First Lady Rosalynn Carter with Jim Jones and a reproduction of a polite letter she sent him in 1977.

These articles are absolutely typical of the way Rudé právo described the United States at this time -- as a place of extreme injustice, exploitation, corruption, crime, danger, and overall chaos. This simultaneously evokes very old European stereotypes about American society and provides a clear contrast with what the Czechoslovak regime presented itself as offering its citizens during the period of late socialism -- the opportunity for all to live a normal, peaceful, quiet, relatively comfortable life.

However, in July 1981, Rudé právo reported allegations by Joe Holsinger that the CIA was responsible for the deaths at Jonestown. According to this article, the People's Temple followers hadn't just committed suicide or fallen victim to a crazed religious fanatic, they were subjected to experimentation through the MKULTRA program, which continued in secret. CIA agents at Jonestown were using various drugs and psychological tactics to brainwash the people there, but the experiment got out of control and the subjects had to be murdered. One month before, they had published speculations that both Jonestown and drug use in the United States were related to CIA experiments, and implied the US supported the mujahideen in Afghanistan to keep Americans addicted to heroin. The July article about Jonestown actually appeared on the front page, which no articles on Jonestown published in 1979 had, and it's the last mention of the People's Temple that I could find. It's very interesting, since none of the articles written in 1979 imply that the victims of the Jonestown massacre were brainwashed -- Rudé právo writers didn't need an explanation beyond the cruelty and alienation of capitalism for why this happened.
