Did anyone pay attention to the way Xi greeted the foreign attendees?
First up was Ban Ki Moon, secretary-general of the UN. Second was the secretary-general of the SCO. I don't think this order was a coincidence, it shows the importance China attaches to the SCO.
South Korea's Park seemed kind of distracted, Xi and Peng had to remind her twice to stand for a photo.
Putin came in last, and walked in with a visible swagger. Being last allowed him to walk together with Xi to their seats, and if you look at Xi just before he shook hands with Putin, I could swear that they were sharing a knowing smile.
It's hard to doubt the level of China-Russia cooperation after seeing this.
