Peru's newly appointed defense minister, Jorge Nieto Montesinos, announced that he will focus on wiping out remnant Shining Path guerilla rebels who continue to operate in the Apurímac-Ene-Mantaro Valley (VRAEM), the country's main coca-producing region. Nieto, formerly culture minister, was named defense minister in a reshuffling of President Pedro Pablo Kuczynski‘s four-month-old cabinet. The VREAM is considered by the UN to be the world's most prolific coca cultivation zone, accounting for a third of Peru's annual production. It is also the country's last significant guerilla stronghold. The integrated counter-narcotics and counterinsurgency effort in the VREAM was dealt a setback in October, when Lt. Wilmer Delgado, commander of an army outpost in the valley, was arrested on charges of collaborating with traffickers and receiving payments of allowing drug flights to operate in the area.
