International investment agreements (IIAs) are important in attracting foreign direct investment, and they are becoming more numerous, varied, and complex. To help policymakers, businesses, and researchers compare and analyze agreements and their implications, the Asian Development Bank (ADB) has created an online database of concluded IIAs involving the Asia and Pacific region. The ADB IIA Tool Kit codifies 15 key investment provisions and includes bilateral investment treaties and investment chapters of free trade agreements. This publication introduces the tool kit and provides a comprehensive analysis of investment treaties and arbitration design.
