Landlocked developing countries are confronted with a range of unique constraints that inhibit full participation in the globalization process. At the same time, economic development and emerging opportunities for interregional trade are stimulating new trade directions which are creating a demand for landlocked countries to provide transit services to neighbouring countries. To help identify physical and non-physical bottlenecks in transit transport processes, ESCAP developed a methodology for analyzing transit transport corridors. The publication outlines this methodology and four case studies on Kazakhstan, Lao People’s Democratic Republic, Mongolia and Nepal. It also contains a framework for recommendations and action plan from the results of studies and sub regional seminars.
