To no one’s surprise, the topic of a “new pattern of great-power relations” came up during the meetings between President Obama and China’s President Xi Jinping. We don’t, of course, know what the two presidents said to each other about it, but PRC State Councilor Yang Jiechi did talk at length about the idea in his briefing after the meeting (mainly in terms of process). In his remarks for the media, US National Security Adviser Tom Donilon cited President Obama on the challenge of “building out the new model of relations between great powers.”
