Of course it is all about China and just how it will make the greatest economic transition in history. Present noise to the contrary, past history happens to be favorable and i presently feel little concern. There are little things to tidy up such as North Korea and yes, South Korea is cringing at the bill. In the meantime everyone knows the outcome and are merely stalling.
Chinese turmoil serves no one and at the same time, the government itself is successfully cleansing itself of what must be described as bad elements. There are critical elements in the Chinese army as well but these typically age out a lot faster. All that noise appears to be the death throes of a faction going with a bit of a fight
Once China successfully completes its transition to slow growth, normal diplomacy will settle remaining issues easily.
