Nguyễn Thủ Thanh, 'A Study of the Use of a Number of Psychological Characteristics of Ethnic Chinese in the Interrogation of Accused and Suspected Chinese Spies'

In 1988 a classified Vietnamese Ministry of Public Security’s in-house professional journal published this article offering ideas on how to utilize the “psychological characteristics” of the ethnic Chinese in the interrogation of suspected “Chinese spies”.  At the time the article was published, the once-close alliance between the Vietnamese and Chinese Communist Parties, which Mao Zedong described in 1967 as being “as close as between lips and teeth”, had deteriorated into a vicious military and political conflict between the two former allies.  Chinese efforts to collect intelligence on and to foment internal opposition against the leadership of the Vietnamese Communist Party were of special concern to Vietnam’s security service, and ethnic Chinese residents of Vietnam naturally became a primary focus of Vietnam’s counter-espionage efforts.
