Don't think that's true. I'm in southeast asia and the largest chinese language groups in the following countries are:

Singapore: Hokkien

Indonesia: Teochew

Philippines: Hokkien

Malaysia: Hokkien (although cantonese popular there)

Thailand: Teochew

Teochew and Hokkien are actually part of the min-nan dialect group which also includes Taiwanese.
