There ie no doubt whatsoever that it has never been the intention of Colombia, Mexico, Panama and Venezuela to arroqate to themselves responsibilities that are not theirs either under the law or as a result of faite accomplis. Nevertheless, in endeavourinq to brinq about a rapprochement and in seeking points of converqence, their Governments are playinq a role that promotes dialoque amonq the disputant nations and reconcilement of the interests of those nations. with the aim of orqanizinq the proposals in a systematic manner, it was decided that the proposals that complemented and improved the Act should be included. The salient features of the amendments made in the leqal instrument in question are listed below: The preamble reflects an endeavour to achieve qeneral aqreements that form the very foundation of the neqotiations.

It contains the principles of an imperative nature that should qovern peacetul coexistence on the part of the countries of the reqian. A qreater deqree ot precision was achieved in the chapter desiqned to restore dnd maintain a climate ot detente and confidence-buildinq, and the link between that chapter and other chapters, particularly the chapters deal inq with security issues, was established more clearly.
