Shanghai copper edged down yesterday, chasing falls in London from an intraday high in the previous session, as investors contend with worries about Chinese growth on the one hand and positive US data on the other.

Western investors fret that Chinese attempts to curb overcapacity in some sectors, including steel, cement and silicon will slow demand growth for base metals.

Copper for three-month delivery on the London Metal Exchange rose $19 to $6,310 a ton in early trade, having ended down 0.3 percent in the previous session, when prices touched a high of $6,408.50.
