Book excerpt: This study examines major challenges and issues associated with developing regional infrastructure through the fostering of regional cooperation in Asia, and provides a framework for pan-Asian infrastructure cooperation. The study's long-term vision is the creation of a seamless Asia (an integrated region connected by world-class, environmentally friendly infrastructure) in terms of both "hard" (physical) and "soft" (facilitating) infrastructure. The soft part supports the development and operation of the hard component. Findings indicate that the benefits of upgrading and extending Asia's infrastructure networks are substantial, and that all countries in the region would benefit. A logistics network is only as good as its weakest link; each country in a regional supply chain gains from infrastructure improvements made in others. Improving connectivity in the region would bring Asia large welfare gains through increased market access, reduced trade costs, and more efficient energy production and use. According to the study, to achieve this Asia needs to invest approximately $8 trillion in overall national infrastructure between 2010 and 2020. In addition, Asia needs to spend approximately $290 billion on specific regional infrastructure projects in transport and energy that are already in the pipeline
