What law career should i pursue to be able to use languages: International Law?

I am interested in law school once I finish college, but I want to practice some kind of law where I would get to use languages. I am working on my French fluency and am also studying Chinese. What is the best field? I am not particularly interested in Public International Law, but am interested in International Business Law. I am not interested in living abroad or travelling every week of the year, but more of something where I would travel once in a while to other countries to negotiate deals,etc. Do most firms have lawyers who specialize in dealings abroad, and would they actually use languages?
