You have a point but we have to bear in mind that China would place great pressure on North Korea to avoid moves that would result in all out war. The last China wants is a unified and democratic Korea on its border; especially one that may still play host to U.S. troops.
We were fortunate that the North Korean shelling on South Korean territory and the sinking of the ROKN corvette did not lead to all out war but who knows what the North Korean leadership might resort to in the future. One thing's for sure however, unless North Korea makes serious moves that result in war, the regime is secure from outside attempts at regime change; especially given that it is widely believed to process nuke devices.
I believe there is a desire not to settle scores with Japan but surpass it's economic and diplomatic clout. Despite all the recent moves and rhetoric China's main focus is its economy and despite distrust and rivalry, Japan plays a vital role with regards to China's economy.
