In order to discover whether there were any differences in negative attitude intensity between the Soviets and Chinese toward United States involvement in the Vietnam war, the Soviet and Chinese English language media broadcasts concerning United States war participation were subjected to a content analysis. The focus of the study was on two contrasting periods of the war: during its height in 1968 and during 1973, a year of unprecedented change in relations between the United States and China. Contents of broadcasts on 80 days, 20 each from the first and last quarters of the two years, were coded and analyzed. Results showed that the intensity of negative assertions was greater during 1968 and that those from China were more intense. While both countries relied on news events as sources, Russian propaganda used argumentative logic as well as emotional appeals, and Chinese propaganda relied on a more vehement, emotional name-calling tactic.
