In response to this perceived growing threat against the regime, on 2 December 1980 the Vietnamese Communist Party Politburo issued Resolution 31-NQ/TW on maintaining internal political security and law and order in the Socialist Republic of Vietnam, with a specific focus on increasing the power and the responsibilities of Vietnam’s Public Security and Police forces, which were subordinate to the Ministry of Interior. 

A speech given by Party Politburo Member Le Duc Tho during a three-day conference of the Ministry’s top Public Security officers along with the Directors of Public Security of all of the nation’s provinces and major cities, where the attendees received instructions on three new Ministry of Interior Party resolutions - one on “the struggle against Chinese spies”, one on “the struggle against American spies”, and one on  “the struggle against the enemy’s ideological attacks.” At the time of the speech, Le Duc Tho was viewed as Vietnam’s second most powerful leader, second only to Party General Secretary Le Duan. 

Le Duc Tho commented that while recruiting Americans would be easy, requiring only “money, women, and drinking and carousing”, recruiting Chinese would require a careful process of political education of the target

This resolution on combatting “ideological sabotage” lumps Chinese ideological propaganda, Western propaganda operations, international human rights and humanitarian relief activities, and religious radio broadcasts and religious missionary activities all together with the spreading influence of Western culture and music in Vietnam as part of a vast, insidious effort by Vietnam’s enemies designed to corrupt Vietnam’s society and to weaken its “revolutionary” spirit in order to cause the overthrow or collapse of the Vietnamese Communist Party and government. 

The over-the-top rhetoric used in this resolution illustrates the widespread paranoia that infected the upper ranks of Vietnam’s Party and security apparatus during this period of the Cold War.  It was not until six years later, in December 1986, that the pressures of growing internal dissension (even within the Party), the country’s desperate economic situation, and reductions in Soviet military and economic to Vietnam resulted in the decision by the Communist Party’s 6th Party Congress to shift to a policy of reforms, called “Renovation” [Đổi Mới] reforms and to new Vietnamese efforts to normalize relations with China and the United States.

A resolution on combatting “American spies." The document calls for Public Security to re-interview all confirmed or suspected “CIA” agents being held in re-education camps and to conduct careful reviews of the enormous volume of documents captured by Communist forces when they took over South Vietnam in 1975 in order to identify and arrest any “stay-behind” agents of the Americans as well as former “CIA” agents who had still managed to evade detection and arrest.

A resolution on combatting “Chinese spies” in Vietnam. The resolution directs Vietnam's Public Security to establish a special interrogation center to which all known and suspected “Chinese spies” who had been arrested would be sent for detailed interrogation by trained professionals. The interrogations would help Vietnam to identify existing Chinese espionage operations and to obtain information on the Chinese intelligence organizations, their plans, and their targets.
