What European countries colonized Asia?
Primarily Holland, Portugal and France; for example Vietnam was french territory until their defeat by the vietnemese at the battle of Dien Bien Phu in 1954 (leading to the start of the vietnam war). Various islands in the pacific are still french and dutch territory (although most were transferred to US control), for example, the Marianas. Britain made inroads into Asia and of course colonised india, and subjugated china (see ‘boxer rebellion’) but mostly it was the aforementioned three.
