Multilateral investment treaties (MITs) are international legal instruments whose purpose is to facilitate social and economic cooperation on a global scale. While there is abundant literature and precedent on MITs generally, authors Kabir Duggal and Mohamed Wahab provide some of the first analysis focusing on the execution of MITs in the Arab and Muslim-majority worlds in this volume of Brill Research Perspectives in Investment Arbitration. This book focuses on two MITs: the Unified Agreement for the Investment of Arab Capital in the Arab States (UAA) and the Organisation of Islamic Cooperation Agreement for Promotion, Protection and Guarantee of Investments Among Member States (OIC). The UAA and OIC are among the oldest MITs in the world, enacted in 1980 and 1988, respectively. But only recently have these two long-dormant treaties acquired special significance. This book provides a comprehensive, critical review of these two treaties.
