Kim Jong-il had appeared in China. He went by train. He went for agreement of relationship between their countries. China was a country that support North Korea. North Korea was a poor country. They were necessary for supporting from other country. China seemed to be happy if Kim Jong-un would be the next leader. Absolutely, North Korea would do like China wanted. Kim Jong-il was expected to retire because he was more over old than to work. He also had a lot of disease that waited for killing him.
In my opinion, North Korea was ever part of China, so China has to help them anyway. Although, North Korea ever made mistake or problem to other countries. I am sure China still give a hand to North Korea. All in all, Blood is thicker than water.
