Memories of historical subjugation and war with China remain raw in Vietnam. In a 2017 survey by Pew, only 10 per cent of Vietnamese said they had a favourable view of China, with which Vietnam fought a series of border conflicts before normalising ties in 1991. In the same survey, 84 per cent of respondents had a positive view of the US.
Hanoi’s growing anxieties about Chinese influence in its backyard have given it common cause with Washington’s stated agenda of ensuring the South China Sea – through which more than US$3 trillion worth of cargo passes each year – remains “free and open”.
