Copper rises in early Asian trading. The prospect of U.S.-Iran peace talks has boosted market sentiment and broadened risk appetite among traders, propelling the metal to a one-month high, ANZ Research analysts say in a note. ANZ also attributes the gains to encouraging commodity trade data out of China, with copper ore and concentrate imports rising almost 7% on year. "This indicates strong demand from domestic smelters despite unfavorable treatment charges," ANZ adds.
