Tai would be the first woman of color to serve as US trade representative if confirmed by the Senate. She currently is the top Democratic trade counsel for the House Ways and Means Committee. Tai's nomination will be seen as a clear sign that Biden is serious about his campaign promise to enforce trade rules on China. She is seen as an expert on China trade policy and oversaw trade enforcement for China during the Obama administration.
