Overcoming the weight of history: 'Getting to yes' in the Peru-Ecuador border dispute

This article presents and analyzes the elements of the Western Hemisphere's longest standing boundary dispute and the crucial role of the region's oldest multilateral conflict resolution mechanism in working out an historic agreement in October 1998. Other factors in combination were also critical for success: an existing international legal framework, multilevel bilateral and multilateral diplomacy, decisive leadership and statecraft, and public diplomacy. The analysis suggests that the final settlement is a significant milestone in international diplomacy, demonstrating that even the most deeply ingrained differences between states can be resolved by the patient and persistent efforts of all parties involved.
