nonsense. Thailand once annexed Camnbodia and Laos, creating Great Thailand, and was about to annihilate Vietnam in an all-out war. why did you intervene? why did you not lift a finger? Vietnam was exausted after the war with America with all industrial and manufacturing basis destroyed. why should we have resorted to a stupid expansion plan? with what resources? Cambodia under the Red Khmer ran amok killing their own people, killing Vietnamese ethnics in the country, attacking Southern Vietnamese border cities, until we said enough is enough.
you can admit, you support Thailand whatever the country does, including aggression because she is your ally.
you attack Vietnam because of your deep hatred, using every pretext.
but ok, we can´t undo the past. no problem we have taken notice and move on.
