The past week has seen big breakthroughs in Asia Pacific economic diplomacy. At the APEC summit, Xi Jinping and Shinzo Abe broke the diplomatic ice in the China–Japan relationship. The United States and China paved the way towards extending the successful International Technology Agreement through the WTO. They also did a game-changing deal that will entrench deep cuts to carbon emissions through to 2025–30. China brought trans-regional (as opposed to Eastern and Western Pacific) integration back to center stage in APEC’s quest for open regionalism.
