He was one of the first Western reporters to visit North Vietnam when he traveled there for the San Francisco Chronicle in the 1960s. Some of his material has been reproduced for A-Level history, within the Vietnam War topic.
Born in England, Greene first visited China for the BBC in 1957. He later produced documentary films, including One Man's China, Tibet, Cuba va!,, Vietnam! Vietnam! and Inside North Viet Nam. These films has been accused of giving a very rosy and one-sided view of the communist society. Some have argued that Greene purposely hid negative information about the extent of starvation in China.  He can be seen as a Fellow traveler.

"Felix Green who was quite a close friend to the late Zhou Enlai of China. Mr. Green had visited China regularly for many years and had great faith in both the country and in communism. He came to Dharamsala with several films, hoping to show me how happy people were in Tibet, and to explain that things were not as bad as we, the Tibetans in exile, believed. He tried to convince me that everything was okay in my country. We talked and argued for three or four days. After many hours of discussion, he finally changed his attitude on most points. In such cases, a good argument based on sincere motivation can produce a positive result, provided both parties strive to be objective. It is very helpful to talk, talk, talk, until a solution is found."
