When did the dragon put its panda mask back on?

Between talk about helping with Iran sanctions and the talk about a currency revaluation you'd think China has somehow realized that playing nicely with others is an essential component of good diplomatic relations. As well as that the US is still the essential nation to have good relations with. I just hope this is a sign that relations will continue to get better and that China will see good relations and cooperation as a better way to get what it wants out of the international system. Belligerency may impress the press but I'm not sure what it has gotten China so far except big headlines. Let's hope that getting them to talk on these issues can lead to some mutually beneficial deals.
