LME copper is relatively subdued as conflicting factors of weak US data combine with a near-term boost from a strike at Southern Copper Corp's Ilo smelter and refinery in Peru, which started Saturday, a LME broker says. "The challenges to the US eocnomy can't be ignored, no matter how positive copper's fundamentals may appear," he adds. LME copper is last at $7,785 a metric ton, +2% from Friday's low.
