The old money Hong Kong residents were bailing out in the 1980’s. I remember reading an article maybe in the WSJ around 1985 that many of them were settling in Vancouver where the local government had no problem letting them in as permanent residents so long as each family had at least half a million dollars in liquid assets to bring with them. Most of them brought boatloads of gold. That’s a great immigration policy.
We have that same issue in SF. The whole city has become Chinatown.
