Meanwhile, managing director of the International Monetary Fund, Christine Lagarde, has called on the United States and China to resolve their trade tensions through rules-based multilateral institutions.

CHRISTINE LAGARDE IMF MANAGING DIRECTOR "Again, I would borrow from Winston Churchill, better chat chat than war war, or something along those lines. So, certainly continuing this dialogue and doing it in a peaceful discreet manner. Not necessarily in front of all of you, not necessarily with communiqués, as you would expect, not necessarily with press statements, leaks, but to conduct that dialogue as much as possible. And to work on the basis of free trade, rules-based multilateral institutions, working and helping."
