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.

This article, published in a classified Vietnamese Ministry of Interior publication, asserted that Vietnam’s economy required international cooperation and support, saying “no country can close its doors and still expect to be able to develop and make progress.” The article also states that the Ministry was now gradually allowing identified “spies” to enter Vietnam so that their activities could be covertly surveilled by the Ministry’s counter-espionage officers
