On December 30, the Trans-Pacific Partnership trade agreement among 11 Asia-Pacific nations comes into effect. The United States was part of the original agreement, but the Trump administration pulled out of the trading bloc. David Dollar talks with Mireya Solís, director of the Center for East Asia Policy Studiesat the Brookings Institution, about the TPP, its effects on tariffs, its provisions on e-commerce, and Japan's role in keeping the agreement alive after the U.S. departed. Discussion also focused on China's relationship from the outside to the pact, the WTO, state-owned enterprises, and how other nations—including the U.S.—could join.
