Haha, so now China wakes up. Countries like China and Pakistan are the ones which made North Korea able to develop all this nuclear technology. It is believed the famous nuclear scientist of Pakistan, Abdul Qadeer Khan, sold the nuclear technique to North Korea and well, China always stands besides the North Korea. Now, North Korea has become so much self sufficient that it will continue it's nuclear programme, even if the worst happens. Bad days for China, I guess.
