You should go to China once you've mastered mandarin. The China economy is booming now and anyone who can speak both English and Mandarin fluently is a huge asset to any firm. You can be a translator for a corporation, you could work for the U.N. and be an ambassador for China, teaching English is also a booming business in China, so you could do the reverse...teach your native language to Chinese. There's plenty of opportunities for someone with those skills. Of course, it would be good to have other marketable skills too...not just language skills.
