The VCP has been characterized by the stability of its leadership. According to Vietnam observer Douglas Pike, Hanoi's leadership was "forged of a constant forty-year association" in which individuals shared "the same common experience, the same development, the same social trauma." Because of their small number, Political Bureau members were able to arrive at agreement more easily than larger forums and hence were able to deal more effectively with day-to-day decisions. As individuals, they tended to take on a large number of diverse party and government functions, thus keeping the administrative apparatus small and highly personalized.

Decisions tended to be made in a collegial fashion with alliances changing on different issues. Where factions existed, they were differentiated along lines separating those favoring Moscow from those preferring Beijing or along lines distinguishing ideological hardliners and purists from reformists and economic pragmatists. The accounts of Hoang Van Hoan, a former Political Bureau member who fled to Beijing in 1978, and of Truong Nhu Tang, former justice minister of the NLF verified the existence in the early 1970s of factions identified by their loyalty to either Moscow or Beijing. They asserted that the proSoviet direction taken following Ho Chi Minh's death in 1969, and particularly after the Fourth National Party Congress in 1977, was the result of the party's having progressively come under the influence of a small pro-Soviet clique led by Party Secretary Le Duan and high-ranking Political Bureau member Le Duc Tho, and including Truong Chinh, Pham Van Dong, and Pham Hung. Until Le Duan's death, these five represented a core policy-making element within the Political Bureau. Whether or not a similar core of decision makers existed in the Political Bureau of the mid-1980s, under Party Secretary Nguyen Van Linh, was not clear.

Differences within the Political Bureau in the mid-1980s, however, appeared focused on the country's economic problems. The line was drawn between reformists, who were willing to institute changes that included a free market system in order to stimulate Vietnam's ailing economy, and ideologues, who feared the effect such reforms would have on party control and the ideological purity of the society. The leadership changes that occurred in late 1986 and early 1987 as a result of the Sixth National Party Congress suggested that the reformers might have won concessions in favor of moderate economic reform. The scale of the infighting reportedly was small, however, and the changes that were made probably were undertaken on the basis of a consensus reached between the hardliners and the reformers. Nevertheless, the results demonstrated that Vietnam's leaders increasingly had come to the realization that rebuilding the country's war-torn economy was as difficult an undertaking as conquering the Saigon government.
