The rapid growth in investment treaties has led to a burgeoning number of international arbitration decisions that have applied and interpreted treaty provisions in disputes between investors and states concerning their respective rights. This flurry of treaties and arbitral decisions has seen the creation of a new branch of international law - the law of investment claims. In this revised second edition, Jeswald Salacuse examines the law of international investment treaties, specifically in relation to its origins, structure, content, and effect, as well as their impact on international investors and investments, and the governments that are parties to them. Specific topics include conditions for the entry of foreign investment and general standards of treatment of foreign investments; monetary transfers; operational conditions; protection against expropriation; dispossession and compensation for losses; dispute settlement, including negotiation, arbitration, and conciliation; and judicial proceedings.
