After graduating from Oxford, he joined the Australian foreign service in 1956, with which he was stationed in Hong Kong and Moscow in the early 1960s: he left the foreign service in 1965 due to his opposition to the Vietnam War, after having become proficient in Chinese and Russian.
[1] He came to Japan for the first time in 1967 as a doctoral student at Australian National University.
Clark is a regular contributor to The Japan Times[3] and is also active in farming and land development in the Bōsō Peninsula of Chiba Prefecture.
Clark believes that there was no violence perpetrated against Chinese students during the Tiananmen Square protest in Beijing in 1989.
