'Gregory Shaffer has written a superb analysis of the crisis in the legal order governing world trade. The core of the book consists of co-authored studies of the engagement with the trading system of China, most significantly, but also of Brazil and India. But the decisive actor now turns out to be the US, which has increasingly lost faith in the system it created. In the future, suggests Shaffer, international rules must grant countries greater room to act and also to react to the actions of others. Yet an agreed interface between systems is also vital if the world is to enjoy a measure of stability and peace.' Martin Wolf, Financial Times
