This introductory chapter begins with a brief discussion of the growth of international investment and the emergence of new field of international law that defines the obligations of host states toward foreign investors and creating procedures for resolving disputes in connection with those obligations. This new law is primarily codified in a vast network of bilateral and multilateral investment treaties, supported by an ever-evolving body of customary international law. An overview of the subsequent chapters is then presented. The importance of investment flows for capital importers and exporters, and the purpose of investment protection is discussed.
