Hi there, just a quick question - is it
in the South-East Asia region
in the South-East Asian region?
Style note: In American English, some compass points are written differently than in British English. The British "south-east" is the American "southeast".
In your sentence, "region" is redundant---"South-East Asia" is a region by definition, so your question is moot. Simply write "South-East Asia".
