Apr 30, 2010. /Lesprom Network/. Chilean industrial conglomerate Copec, one of the world's largest wood pulp exporters, said it planned to invest $725 million in 2010, as Reuters agency informed Lesprom Network. Copec's forestry unit Arauco was battered by a massive earthquake on February 27, which knocked out several of its plants in south-central Chile, and its first-quarter earnings are expected to be affected. Copec is the most heavily weighted stock on Chile's bourse.
