The development of the modern global trading system has been extremely rapid - and not without controversy. The WTO (and its precursor, the GATT) have provided not only a set of multilateral rules and disciplines but also a forum for negotiation and a legal mechanism to settle trade-related disputes. This important two-volume collection includes key papers that provide a pertinent historical perspective as well as addressing the current and future issues that confront the trading system. The first volume focuses on the need for and genesis of multilateral trade rules and disciplines, and also examines the core non-discrimination rules. The second volume looks at reciprocity rules; the notification and surveillance of trade policy; the modalities for negotiating market access; and the difficulty in converting non-tariff trade measures into tariffs.
