I want to study business in college and I would love to study a language with it! There are courses available in the college of my choice to do business with chinese or japanese but what im wondering is which would be of more use to me if I was continue with my business career when finished college?
I was actually thinking of Spanish as well because that would be a whole lot easier and I love it so thanks for the advice rye
And hey, i can learn Chinese after school if I really want to 
Hey mate great question.
To answer your question I would definitely go with: Mandarin ("Chinese").
Mandarin is spoken by more than a billion people – sure, most of them are in China but China is fast-becoming big business.
Not only is China rapidly becoming the largest economy in the world, but they also do a lot of business with Australia.
My great uncle works with chinese businessmen for mining, he took the courtesy of learning some Mandarin from scratch. He can now make his way around some conversations speaking only Mandarin. Sure it’s nothing like English [I dropped it after a year or 2, I was young, didn't like the tutor, didn't like the language], but if a 70-something businessman can make the effort, then I’m sure you can to.
Being bilingual in general is always a plus and I’d recommend being bi or trilingual to anyone. Knowing Mandarin will definitely give you an advantage over your competition [say if you're applying for a job] and would look good on any resume.
Best of luck mate!
