Ponce-Castro Oyanguren Protocol Signed Between Ecuador and Peru

The Ponce-Castro Oyanguren Protocol was established as a diplomatic effort to address the longstanding border dispute between Ecuador and Peru. This conflict had its roots in earlier territorial claims and agreements, notably influenced by the Salomon-Lozano Treaty, which had been signed between Colombia and Peru. The treaty resulted in the transfer of land that Ecuador claimed, leading to protests from the Ecuadorian government. The tensions escalated as both nations sought to clarify their borders and assert their territorial rights, which had been complicated by previous treaties and regional conflicts. Under the Ponce-Castro Oyanguren Protocol, Ecuador and Peru committed to resolving their differences through direct negotiations and agreed to seek arbitration from the United States. This marked a significant shift towards a more peaceful resolution of territorial disputes in the region, emphasizing diplomacy over military confrontation. The protocol laid the groundwork for future discussions and agreements, ultimately contributing to a more stable relationship between the two nations. The involvement of the United States as an arbitrator highlighted the international dimension of the dispute and underscored the importance of external mediation in resolving conflicts in Latin America.
