By virtue of this exchange of notes the process of demarcation of the Peruvian-Ecuadorean frontier was brought to a conclusion, upon execution of the Protocol of Peace, Friendship and Boundaries signed between Peru and Ecuador in Rio de Janeiro on 1942, which determined the boundary line between the two countries. In the Western Section, it has been established that the boundary line shall pass through the so-called old bed of the River Zarumilla. Peru undertakes, by this agreement, to take the necessary steps to guarantee the supply of water necessary for the life of the Ecuadorean villages on the right bank of the so-called old bed of the river Zarumilla, fixed as the frontier.
