well, the un has a lot to do with rebuilding cambodia after the cambodian genocide. also, after the paris peace agreement, even corporations such as the world economic forum "helped". not directly, but they did play a role. so imo, the west "helped" rebuild and develop cambodia to what it is today. it was an investment opportunity for the us and other western nations, so in a sense cambodia became "westernized". where were these countries that came to "help" while 1.7 to 2 million people were being genocided from 1975 to 1979? granted, the cold war played a major part in this as well, but the only country that came to cambodia's aid was vietnam. there is a lot of very strange things surrounding cambodia, vietnam and south east asia in general since the early 70's. i don't know much about cambodia prior to the 1970's.
