The industrialization drive was meant to be primarily a Peruvian process not totally excluding foreign investors but definitely not welcoming them warmly. In that spirit, the Velasco regime immediately nationalized IPC in October 1968 and, not long after that, the largest copper mining company, while taking over other foreign firms more peacefully through buy-outs. The government put into place new restrictions on foreign investment in Peru and led the way to a regional agreement, the Andean Pact, that featured some of the most extensive controls on foreign investment yet attempted in the developing world.
