Cenepa War
Figures given for losses during the Cenepa War vary widely, especially regarding human casualties. Ecuadorian military sources put the casualties at 34 killed recognized by Comando Conjunto de las FFAA del Ecuador and 154 killed and wounded recognized by Asociación de ex combatientes del Cenepa, Quito, Ecuador. As of February 2005, an Ecuadorian Cenepa war veterans' association had a membership of 131 ex-combatants, some of them with long-term health disorders caused by the war.
ALDHU, a human rights NGO, has put the total number of mortal casualties for both sides at around 500. This figure was also given by Ecuadorian senior officers after the war, reflecting the fact that Peruvians found themselves attacking well-protected Ecuadorian positions and subjected to continuous ambushes and well-aimed artillery and rocket fire from the heights of the Condor range.
Argentina–Peru relations
In 1995, Peru was involved in the Cenepa War, a brief thirty-three-day war with Ecuador over the Cenepa River sector of the Cordillera del Condor territory in the western Amazon basin. Argentina, Chile, Brazil, and the United States, as the guarantors of the 1942 Rio Protocol that had put an end to the Ecuadorian–Peruvian War earlier that century, worked with the governments of Peru and Ecuador to find a return to the status quo and end their border disputes once and for all. On 2005, General Víctor Manuel Bayas, former Chief of Staff of the Ecuadorian Armed Forces during the Cenepa War, made a series of declarations in regards to the armed conflict between Peru and Ecuador. On March 21, 2005, General Bayas was asked by the Ecuadorian newspaper "El Comercio" if Chile had sold armaments to Ecuador during the Cenepa War, to which he replied: “"Yes, it was a contract with the militaries during the conflict."" Furthermore, General Bayas revealed that Argentina and Russia had also sold weaponry to Ecuador during the conflict.
