HELP! Which kinds of international schools are in which districts?

Dear everyone -

I really hope, that you are able to help me out.

I am studying antropology, and before writing masters thesis, I will go to Vietnam to do fieldwork.

What I am really interested in, is the way the international schools in Vietnam are organized in different districts. Or so I have been told. I have been told, that in district 7, there are mainly international schools for koreans, japanese, chinese and other asians, whereas in district 2, there are mainly Western international schools.

Is this true?
And if yes, I hope, that someone can please elaborate on this, since I find it really interesting.

I would love to examine the whole concept of international schooling in HCMC - and I need all the help I can get :-)

THANKS EVEYONE!!
