It all depends on what you expect to do professionally. In general, English is the most useful, simply because it is used the most to communicate from one business to a business in another country. However, if you think you will be dealing with South American firms, than obviously Spanish would be your best choice. In short - if you will be dealing with a particular country a lot (Japan, U.S., etc) then learn that country's language. If you will just be dealing with international firms in general, English is probably best.

certainly, the first English, because English is the universal language. the second is Japanese, n the next it's up to ur choice ^^

hmm,it is very nice of you to share this with me,haha

The 6 languages of the UN would be a good selection Arabic Chinese (Mandarin) English French Russian Spanish Also China is starting to do a lot of trade with Africa, French and English will help there. And Swahili is used in a lot of countries on the African eastern sea board.
