Nope, it's quite different ! Chinese is Subject+Verb+Object , but Korean is Subject+Object+Verb ! If you have any questions , plz contact me on Skype: leejangkeum I'm native speaker and also know much korean !

Chinese, Vietnamese : Isolating language, see http://en.wikipedia.org/wiki/Isolating_language Korean, Japanese: Agglutinative language, see http://en.wikipedia.org/wiki/Agglutinative_language

I personally would not say similar, if we are talking about grammar. Korean is a subject-object-verb language, some verbs are conjugated, and the language uses honorifics (like Japanese). Chinese is a subject-verb-object language, verbs are not touched, and honorifics are minimal.
