International rules of trade among nations are established by an international organization known as the World Trade Organization (WTO) and these rules have a profound impact on individual producers and consumers all over the world. Establishing an efficient mechanism for settling disputes between members of the WTO has always been of key importance. Without an effective means of settling trade disputes, there would be no incentive to abide by international trade rules. This chapter outlines the dispute settlement mechanism the WTO uses to resolve complaints by member States about trade violations of other member States.
