Published in association with Regional Centre for Strategic Studies, Colombo. Good fences make good neighbours', wrote Robert Frost some sixty years ago. The trouble in South Asia is that our fences are overtly strong, and yet they do not help good neighbourliness. The need for fences is being increasingly questioned in many parts of the world today, yet ours are getting higher and stronger. Are they serving a purpose? Some six decades after Frost's remarks the fences between nations are steadily coming down. The European Union is integrating rapidly and border check-points are disappearing. Yet, in South Asia the obstacles to movement are immense. This has been a major concern at the RCSS. What are the reasons for stringent border controls? Why are they imposed and what purpose do they actually serve? Who gains and loses as a consequence? What are the procedures involved and why have they come about? A collaborative research project sponsored by the RCSS addressed these and related issues. Four distinguished experts, one each from Bangladesh, India, Pakistan and Sri Lanka have separate chapters examining a particular facet reflecting their respective, perspectives. Slightly different from each other yet comprising a comprehensive whole.
