Ecuador Peru Boundary

The objective of this study is to provide the background required for an understanding of the boundary dispute between Ecuador and Peru, a hardy perennial among inter-American controversies. It is not designed to propound any particular thesis, much less to take sides in the dispute. Evaluation of the significance of the positions adopted by the parties over the years have been included. Primary attention has been focused on the period after the entry into effect of the Rio Protocol of 1942 which attempted to fix the boundary between the rival states and which was guaranteed by Argentina, Brazil, Chile and the United States. Very little has previously been published on the efforts of the guarantors to work out the problems which arose in the execution of the protocol. These problems proved so intractable that the demarcation of the boundary has not yet been completed, leaving the guarantors with a residual responsibility which they may yet be called upon to discharge. In addition to the survey of the post-1942 period, it was considered desirable to include information regarding the origins of the dispute and earlier attempts at solutions. Much of this material will be appearing for the first time in English.

Although the 1995 Cenepa War between Ecuador and Peru was the first military conflict in South America in over 50 years, the Ecuador-Peru relationship has been one of enduring rivalry. This text analyzes the mediation process that followed the 1995 war.
