MEXICO CITY, July 30 (Reuters) - Grupo Mexico, a major copper producer, said it maintains a "very positive" long-term outlook for copper growth in Asia, a top executive said on Wednesday, shortly after Washington signed an order imposing 50% tariffs on imports of the red metal.
Speaking in a call with analysts, Leonardo Contreras, finance chief of Grupo Mexico's mining division, said the company continues to monitor global changes before it decides whether it should reopen a mothballed smelting project in Arizona.
