China Copper Futures Tumble to Limit-down on Wed.

Copper futures on the Shanghai Futures Exchange (SHFE) fell sharply Wednesday afternoon, by the daily limit down of 5 percent, following losses on London and U.S. markets, as the U.S. financial sector bailout plan failed to impress equities markets in the U.S. and Asia.

China's imports of copper and copper products in January fell 2.6 percent on year to 232,701 tons, according to statistics released by China's General Administration of Customs on Wednesday.

The copper metal still faces weak fundamentals and lower demand in coming sessions, said analysts.

SHFE benchmark April copper contract ended 1,470 yuan lower at 27,920 yuan a metric ton Wed.

Prices of aluminum and zinc futures at SHFE also tumbled following copper losses. The benchmark aluminum contract shed 1.9 percent to settle at 11,825 yuan a metric ton, and the benchmark zinc contract dropped 2.7 percent to settle at 10,410 yuan a metric ton.
