What Chinese languages are spoken in South East Asia? With the abundance of immigration and emigration in Asia it would be interesting to know where the Chinese languages moved to as well. 

The effect of Chinese characters on Japan and Korea goes without saying, but how about South East Asia?

Wikipedia's page Language and overseas Chinese communities mentions the subject a little but mostly in gloss.

Any ideas?
Page 2 of《泰国的西南官话》by 肖自辉 has this little little insert, which is quite nice:


  



Malaysia speaks: Hokkien, Teochew, Cantonese and Hakka.
Singapore speaks: Hokkien, Hakka, Cantonese, Teochew and Hainanese
Indonesia speaks: Hokkien, Hakka, Cantonese and Teochew.
Brunei speaks: Amoy and Hakka.
Philippines speaks: Hokkien and Cantonese.
Vietnam speaks: Cantonese, Teochew, Hakka, Southwestern Mandarin, Hokkien and Hainanese.
Laos speaks: Teochew and Southwestern Mandarin.
Cambodia speaks: Teochew.
Thailand speaks: Teochew, Hakka, Cantonese and Southwestern Mandarin.
Myanmar speaks: Southwestern Mandarin, Hokkien, Cantonese and Hakka.


It's not that surprising to see Cantonese and Min, along with its other branches, getting big representation. Southwestern Mandarin on the other hand is a bit of a shock.
