(Adds Standard Chartered comment, details; updates prices) SYDNEY, Oct 17 (Reuters) - London copper paused for breath near three-year highs on Tuesday as it faced headwinds from a stronger dollar, but renewed optimism over China's economic outlook has lent support to prices. Metals prices could find more support if China's National Party Congress this week unveils polices that extend the country's environmental-led industry reform, said Standard Chartered in a report. "Any signalling by policy makers that the rigorous application of environmental regulations on industry and seasonal pollution-reducing policies will be the norm over the next five years will be a price-positive development for the complex." The twice a decade National Party Congress begins on Wednesday.
