The importance of transport corridors for trade and development, including for some of the poorest countries in the world, is widely recognized in this book. A new consensus has also emerged that reducing trade costs and improving access to corridors is not just a matter of building infrastructure. The policies that regulate transport services providers and the movement of goods along corridors are important determinants of the social rate of return on such infrastructure investment. This book avoids optimistic assumptions regarding the prospects for new high-level agreements and decisions to facilitate transit or the possible benefits from increased use of technology. Instead, the authors argue that much can be done through the implementation of readily available existing tools. The use of these tools is often hampered by not only capacity constraints; but, equally if not more important, a lack of commitment. Political economic factors in both the landlocked countries and their transit neighbors must be recognized and addressed. This book offers examples of possible implementation strategies that, while challenging, should in principle help in overcoming these political economic constraints. The main message is that to bring about efficient trade corridors governments and stakeholders should focus on properly implementing the fiscal, regulatory, and procedural principles for international transit that encourage quality-driven logistics services. The various implementation challenges are the primary focus of this book.
