Rio Negro Treaty (Treaty of Cuenca)

The Rio Negro Treaty, also known as the Treaty of Cuenca, was signed in 1942 between Ecuador, Peru, and Colombia to peacefully resolve border disputes along their Amazon River regions. The treaty established a mutual agreement not to use military force and to settle disagreements through negotiation and international arbitration. It aimed to maintain peace and stability in the border areas, fostering cooperation and reducing the risk of conflict during a tense period in South America. The treaty remains a significant diplomatic framework for managing border relations among these nations.
