U.S for sure. INSEAD and LBS can be considered if you don't mind going back to China right away. Tuition won't be a significant factor in the long run. Top management consulting firms and most of MNC won't recruit in China for the level of jobs that you will look for.
BTW, keep in mind that it won't be easy to find a RIGHT job even you go to top 3 schools. Spend the next year on getting your spoken english to the next level. Seek professional help if necessary. It may cost your few grand. Comparing with tuition, it gives your biggest bang for your buck. Sorry, I assume that your spoken english is not perfect. Believe me, 70% of Chinese students in top 10 school have issues in spoken english.
