Growing U.S.-China rivalry undoubtedly poses a profound threat to the multilateral trading system. In “Governing the Interface of U.S.-China Trade Relations,” Gregory Shaffer provides a highly nuanced and balanced analysis of the nature of this threat and potential solutions to address it. Yet managing trade conflict between the United States and China is, I argue, only one of the twin challenges currently facing the multilateral trading system. The other is how to rein in growing economic coercion and the arbitrary abuse of power by dominant states in the system. The United States and China have each become highly disruptive forces in the liberal trading order—not simply because of their bilateral trade relations but also, and just as importantly, because of their behavior toward the rest of the world. Both of these countries have increasingly turned away from trade multilateralism and toward aggressive unilateralism and the raw use of coercive power in their dealings with other states. It is this flagrant disregard for the rule of law on the part of the system's two dominant powers that has thrown the World Trade Organization (WTO) into crisis and ultimately poses the greatest threat to the global trade regime.
