Copper Tubing

Chinese companies and investors are stepping up their purchases of industrial commodities such as copper, in a show of confidence in the global economy that stands in contrast to the turmoil in western markets.

The wave of buying is providing support for metals and minerals prices after commodities prices fell this month at worries about a double-dip. Senior executives at trading houses, mining companies and banks said Chinese consumers had used the recent drop in prices to rebuild stocks.
