After the Vietnam War, unified Vietnam charted a twisty trajectory in search of its place in the world. This course went through five major turning points - in 1977, 1986, 1989, 2003, and 2014 – as the ruling Communist Party responded to fundamental changes in Vietnam’s strategic environment. Reflecting competing worldviews in the elites, these responses resulted from the struggle between two long-term choices: to reject the Western-led world order and oppose Western influence, or to accept the Western-led world order and adapt Western influence. At a deeper level and from a long historical perspective, this struggle was complicated primarily by Vietnam’s location vis-à-vis China and the major transoceanic routes. If the Vietnam War ended with the triumph of the anti-Western choice, the post-war period has seen Vietnam alternate between anti-Westernism and international integration. Decades of zig-zagging eventually turned Vietnam from an “outpost of socialism” and “spearhead of the world national liberation movement” to an “engaged and responsible member of the international community” and from a fierce opponent to a discreet ally of the United States, while not fundamentally shaking its commitment to denying Chinese regional dominance.
