Rio Tinto’s Copper Dream Stirs Water Worry (Video)

(Updates to add comment from Rio Tinto on shipments in second paragraph.)

Rio Tinto yesterday postponed today’s scheduled first shipment from the $6.6 billion mine, saying it will start as soon as the government indicates support. Bloomberg's Yuriy Humber reports.
