International Border Agency Cooperation (iBAC) is a key element of the modern trade facilitation philosophy that seeks to make cross-border trade and logistics faster, cheaper and more predictable while ensuring adequate compliance and regulatory control over the traffic. This report studies international Border Agency Cooperation from the perspective of the fiftyseven member countries of the Organization of the Islamic Conference (OIC). The goal of this research is to raise awareness of international Border Agency Cooperation, and to highlight practical recommendations for advancing cross-border Border Agency Cooperation and trade facilitation, among the OIC members and their trading partners. To achieve this goal, this report provides a generic six-step roadmap that proposes and prioritises activities for simplifying, harmonising, rationalising, and standardising border management. This study is mandated by the OIC Standing Committee for Economic and Commercial Cooperation (COMCEC) and executed by the Cross-border Research Association (CBRA).
