The International Law on Foreign Investment is a survey of the Public International Law applicable to the protection of foreign investment, examining the different techniques adopted by States for attracting foreign investment and for ensuring that foreign investment serves their economic objectives. The work compares foreign investment legislation and assesses their legality in the light of international norms. It considers the changing perceptions of foreign investments and the new forms of foreign investments that have emerged from these changes. The risks to foreign investment are identified and the ways of avoiding them are discussed. The effectiveness of the different methods of risk avoidance are also surveyed. In considering these issues account is taken, not only of the law, but also of the relevant literature in economics, political science and other associated disciplines.
