The Chinese put uniforms on everyone to control them socially.
Obama should be wearing a dress Western outfit with cowboy boots and a Stetson.Fat chance of that from Obama though. This goes to show just how much of a surrender noodle Obama truly is.
Notice in the group picture that Putin is the guest of honor in the center, and Obama is shoved down on the end with the wives. Open insult by the Chinese and he just takes it.
