Laotian modern relations with Vietnam had secretly set the strategy for the Lao People's Revolutionary Party (LPRP) during the struggle to achieve power, and the "sudden" opportunity to establish the Lao People's Democratic Republic in 1975 left no leeway to consider foreign policy alignments other than a continuation of the "special relations" with Vietnam.
The relationship cultivated in the revolutionary stage predisposed Laos to Indochinese solidarity in the reconstruction and "socialist construction" phases and all but ensured that relations or alignments with China and Thailand would be wary and potentially unfriendly.
The revolution was simply entering a new phase in 1975, and the LPRP leaders congratulated themselves upon ousting the "imperialists" and looked forward to advice and economic as well as military support, which was not available from any neighbor or counter revolutionary state.
They formalized governmental contacts with their mentors at biannual meetings of the foreign ministers of Cambodia, Laos, and Vietnam starting in 1980 and through the joint Vietnam-Laos Cooperative Commission, which met annually to review progress of various projects.
In the LPRP, long-standing collaboration and consultation at the very top made special committees unnecessary, whereas in the LPA, the Vietnamese advisers, instructors, and troops on station constituted a pervasive, inescapable influence, even though they scrupulously avoided public exposure by sticking to their designated base areas.
Cooperation in the military field was probably the most extensive, with logistics, training, and communications largely supplied by Vietnam throughout the 1970s and 1980s (heavy ordnance and aircraft were provided by the Soviet Union).
[1] The resources that Vietnam was able to bestow upon its revolutionary partner, however, were severely limited by the physical destruction of war and the deadening orthodoxy of its economic structures and policies.
However, it could put in a good word for its Laotian apprentices with the Soviet Union, which in turn could recommend economic assistance projects to its East European satellite states.
In 1992 the long-standing Vietnamese ambassador to Laos, a veteran of fourteen years' service, characterized the relationship as composed "d'amitié et de coopération multiforme entre les pays" (of friendship and diverse cooperation between the two countries).
Thus, Vietnam remains in the shadows as a mentor and emergency ally, and the tutelage of Laos has shifted dramatically to development banks and international entrepreneurs.
