New Wikileaks tells us nothing that hasn't been related to journalists "off the record" in the past years. Pentagon spokesman Gates had it right when he said words to the effect that countries do not deal with the US because they like us but because they have to. Latest revelations show Pakistan is unstable and there are worries about its nuclear facilities; Arab countries are worried about Iran; the UN is a den of crooks and spies; and Prince Andrew is an oafish ponce.
What's more revelatory, given the current situation, is the expression about China's concern regarding North Korea. One of the main factors in the development of imperialism is that "allies" of the US for example are increasingly tending to defend their own national interests as centrifugal tendencies take control. The Wikileaks conversions on this show that it is also a factor with the North Korean ally of China, ie, the development of each for themselves predominates and becomes a more dangerous and unstable factor.
The leaks show a Chinese ambassador calling North Korea's nuclear technology "a threat to the whole world", "a spoilt child". Chinese concern for the stability of the Great Leaders' regime in undoubtedly genuine but the Chinese have also turned it into a problem for the US as well. We should also remind ourselves here that these leaks are low level secrets and do not represent the strength of the policies and protocols that are way above these levels of classification and represent the reality of more substantial imperialist machinations. We won't be seeing them. But they do point to tensions and the fear of the Chinese ruling class about the collapse of North Korea and an influx of refugees across its borders.
I find the idea that the Chinese bourgeoisie is anywhere near taking the view that it would prefer a unified Korea under the aegis of Seoul and anchored in a "benign alliance" with the United States (providing the latter keeps its troops below the demilitarized zone) difficult to believe. From this certain writers have extrapolated China playing a fully responsible role in "the family of nations" and confrontation would be a thing of the past. Not a likely scenario.
China will not precipitate a crisis in order to bring about the collapse of the North Korean regime (another idea expressed) and its present strategy is to prop it up and, in the first place, to get the latter back into the six-party talks with Seoul, the US, Japan, China and Russia. And the clear message, delivered back to China from the US via Seoul, is there's no chance of even talks about talks.
North Korea is overcoming US sanctions largely through Chinese front companies (Washington-based Institute for Science and International Security Report) which is enabling it to develop its nuclear weaponry. The report also notes the constant flow of money and technology from China to North Korea and the great number of businesses that tie the two ruling classes together.
North Korea is an unstable regime and this obviously concerns China. But for the period to come this remains (deliberately or not) a bone of contention between the US and China and part of the instability of the whole imperialist situation.
