This Handbook provides an overview of the obligations contained in international investment treaties and the risks that governments face if their officials violate those obligations. The Handbook addresses key concepts through a question-and-answer format, provides practical examples, and contains a checklist for decision makers to give these concepts concrete meaning in the day-to-day work of government. This Handbook is intended to provide information to government officials at all levels and in all branches (executive, legislative, judicial) to help them avoid violating international investment obligations and potentially triggering an international investment dispute.

The Handbook is the product of consultations with governments throughout Asia-Pacific Economic Cooperation, with the funding and support of the Australia Department of Foreign Affairs and Trade. It is not a substitute for specialised legal advice.
