However:

KUALA LUMPUR, Jan 10 (Reuters) - London copper edged
up on Tuesday, rebounding slightly from a drop in the previous
session, as data showing a rise in imports by the top consumer
China supported prices, but concerns over the euro zone debt
crisis kept a lid on gains.	
    Three-month copper on the London Metal Exchange 
climbed 0.4 percent to $7,526.50 a tonne by 0341 GMT. The
industrial metal lost a fifth of its value last year, the first
annual decline in three years.	
    The most-traded March copper contract on the Shanghai
Futures Exchange slipped 0.4 percent to 55,280 yuan
($8,800) a tonne.	
    Imports of copper by China, which accounts for 40 percent of
the refined metal's global consumption, rose 12.6 percent to
508,942 tonnes in December from 452,022 tonnes in the previous
month, data from the General Administration of Customs showed.
 	
    "Easing credit conditions could be driving greater
willingness to restock and the arbitrage window opened up in the
latter part of 2011," said Nick Trevethan, senior commodities
strategist at ANZ Research in Singapore.	
    "Our outlook for China remains positive, but we are
concerned of the risks posed by Europe. However in this round of
data at least, Europe has limited impact on export demand." 	
    China's total exports grew 13.4 percent in December, just
below the 13.5 percent forecast in a Reuters poll of 23
economists.
