My understanding is that the Peruvians were about to ask us to pull the visit so that relations would be maintained, and as a measure to maintain regional dynamics, however the Peruvian Foreign Minister jumped the gun. The Peruvian press etc is all over him for kowtowing to Argie pressure, there is bad feeling between the countries as Argentina sold weapons to Ecuador during the scuffle between them in 95, despite being one of the 4 nations who stepped in to broker peace. Tye Minister is one of the few left wing members of a majority right wing cabinet....for now.
