The first edition of WAW is being held virtually by video conference during a five-day period from November 29 to December 3, 2021. This edition of WAW consists of 14 sessions and networking events connecting the members of Washington D.C.'s international arbitration community to the rest of the world. These panels will follow a dynamic format and foster an open discussion about the future of international arbitration. They will shed light on new arbitration techniques, focus on developments and evolving interpretations and views, and discuss the best practices for international arbitration in the new virtual reality.

On behalf of all of our supporters, panel speakers and moderators, we welcome newcomers and experienced practitioners alike to our city and arbitration community.
