Barack Obama and Xi Jinping casually strolled around the exclusive Sunnylands retreat near Palm Springs, California, smiling to display warm and friendly U.S.-China relations. It was the summer of 2013, and things seemed to be going well between the reigning superpower and the ascendant one.
Obama was a fairly seasoned second-term president; Xi, the new Chinese leader, had just taken the reins from Hu Jintao, and nearly everyone in Washington viewed him as the embodiment of a new, more hopeful chapter in U.S.-China relations. Obama spoke of a “new model of cooperation” with China and said the United States welcomed the “continuing peaceful rise of China as a world power.” It was the beginning of a new era in U.S.-China relations.
