My understanding is that China has a very different relationship with North Korea and a very different perspective on foriegn policy. China tends to emphasize North Korea's stance as a reaction to US/South Korean provocations. China also has a significant population of Koreans and significant trade with North Korea, and fears the destabilizing effects of North Korean collapse more than the destabilizing effects of North Korean actions. Finally, China's policy is that countries should not peer to closely into the domestic affairs of foreign countries. North Korea's strategy is to deter foreign aggression against itself. As this article reveals, it has been an effective strategy, because the costs of war on the Korean peninsula are so huge despite the North's technological deficit.
