Ian Bremmer shares his insights on global politics this week on World In :60.

How will the US respond to China's saber-rattling?

Well, I mean, in part, China's saber-rattling is a response to what the United States has already been doing. In particular, significant export sanctions that are not really about competition. They're really about containment of China in some of the top areas of economic development, technological development that they are trying mightily to be world leaders at. There is a level of direct confrontation that the Americans are pushing on and the Chinese are now increasingly public. I thought that it was interesting that Xi Jinping decided to make those statements about the United States directly. He usually defers to the so-called wolf warriors, some of the members of the press so this is getting chippier and the ability to maintain and manage a calm and engaged, interdependent US- China relationship is getting harder. There's, as they say, downward pressure on that call going forward.
