It is very hard to do anything. For decades, both China and the Soviet Union supported North Korea as a buffer to keep American soldiers away from their own borders. Neither country liked the North Koreans very much, but they didn't like each other very much either, so the Koreans could play one off the other to get away with whatever they wanted. Moreover, there was no possibility for the Americans or the South Koreans to do anything without risking war with the Soviets and/or the Chinese. This situation changed somewhat with the fall of the Soviet Union. I believe the article has a chart of the freight tonnage crossing the border that shows a sharp drop off at this time (I saw the chart somewhere last night). The loss of aid from the Russians exacerbated the North Korean famine in the 1990s. The Chinese still continued to support the Koreans as a buffer state, however. Recently, it has become clear that the Chinese have grown somewhat ambivalent to the whole situation (wikileaks, for example). It is now unlikely that they would defend North Korea in a war, but they do still think of it as their backyard. For the Americans and South Koreans, the prospect of going to war against the North with a possibly nuclear armed army of 2 million soldiers is not very appealing. I would say that the Chinese influence is growing as the Koreans have not been able to play them off against the Soviets for the last 20 years. More and more (capitalist) Chinese investment seems to be occurring, and the country seems to be opening up ever so slightly, though the Koreans still act pretty randomly. One final note, I have been watching North Korea for a few years, and I would say there has been a very important sign of opening up. Last night, I watched a video from a tour where the guide at a collective farm talked openly if not completely honestly about the famine. A few years ago, they would not have even admitted that the famine occurred and blamed it on American propaganda. The door has been wedged open a little bit, and I am hopeful that a new generation of leadership that has grown up without the benefit of Soviet support will allow things to open further. Then, we may be able to do something productive about the atrocities that sadly still occur.
