I think it is about time China stepped up and became the Super power that they are and at least deal with some of the problems on there own borders . They are quickly becoming a economical power as well and if they intend to keep trading with us in the west then they have an obligation to help with the problems in the world rather than do nothing or make them worse.
If this does not happen China will slowly become what the USSR was for 50 years , and the world does not need this. North Korea needs to be dealt with and China should do it!
