Just like the Pilgrams landing in America in the 1600s; the Vietnamese landed where ever they were welcomed in the 1970s.
1975 onwards.
The northern & western coastal regions would seem a good bet.
"Vietnamese Boat People"
Vietnamese refugees
because they had nothing else to do
I heard some people went to Malaysia
There was a exodus of Vietnamese people called the boat people to Australia and New Zealand.
Most Vietnamese are not refugees and most refugees are not Vietnamese. Those Vietnamese that became refugees in the 1940s-1980s fled the violence of the Indochina Wars, which destroyed Vietnam and made life difficult for many Vietnamese.
Take a guess, Probably Vietnam !
why did the vietnamese persecute french missionaries
By plane...boat...
