latest revelation from the ongoing Wikileaks 'scandal' - quite who is being scandalised is, of course, open to debate - is that the Chinese government is consistently 'frustrated' by North Korea's belligerent regime, alleging that it has on occasion behaved like a "spoiled child".
The revelation - stemming from a Chinese foreign ministry official - is interestingly timed, given that Pyongyang recently shelled a South Korean island that killed two and which has threatened to reignite hostilities in the peninsula.
The reason why this Chinese ambivalence towards North Korea is particularly interesting is that the 'rogue state's' leader Kim Jong-il has often relied on apparent Chinese backing to dissuade any potential attack by Seoul or the United States. That the Korean War never officially concluded with a peace treaty after the 1953 armistice has meant that this last vestige of the Cold War has never really cooled down completely.
The rest of the international community, too, has long pressed China to take more action over North Korea and its isolationist leader whenever Pyongyang is giving particular cause of concern. This 'leak' appears to suggest that the Supreme Leader is not as close to Beijing as he might like to think...
