"This is a positive measure because the agreement was reached in an intelligent way by both governments and does not affect Peru's sovereignty in the area or
the ongoing trial between Peru and Chile at The Hague," Ferrero told Andina news agency.
The agreement to remove landmines from the common border areas was announced Friday by Peru's Foreign Minister Rafael Roncagliolo, after meeting with his counterpart in Chile, Alfredo Moreno.
The South American nations will appoint an international company to locate and remove the devices along the frontier.
Ferrero said this was a clever measure that will help clear landmines posing extreme danger to civilians, "without affecting the sovereignty of both nations and without generating distrust and conflict."
In February this year, Chile closed its main border crossing with Peru after torrential rain washed landmines near the road linking Arica in Chile and Tacna in Peru. The road was reopened after army bomb disposal experts detonated a number of devices in controlled explosions.
