During an interview with CNBC released on Monday, Treasury Secretary Janet Yellen stated that "the great majority of" trade between the U.S. and China "is uncontroversial" and she's working to ensure that the geopolitical relationship and national security worries won't trump the economic relationship and "we don't have an unintended escalation of tensions, that we understand one another's red lines, we avoid misunderstandings, and we preserve economic interactions that are beneficial to both sides."
