Do koreans dislike chinese and south-east asians generally?

I've got a korean friend who expressed her dislikes for chinese girls and south-east asians. She said south-east asians are usually poor and mannerisms are bad and chinese are after money. I'm sadden by her frequent comments on this. Many times she gave the indication that korea and koreans are clean, hygienic and good. She doesn't like japanese too. However she uses japanese products.
