The Aluminum Corp. of China (Chinalco), the country's top aluminum producer, said on Thursday its sales revenue reached 142 billion yuan (21 billion U.S. dollars) last year.

The company has yet released its profit figures. Sales revenue was 126 billion yuan in 2008.

Chinalco said its business operation was at a steady running despite the international financial crisis.

The company also made what it said "substantial" progress in business restructuring, including eliminating outdated and highly energy-consuming production capacities.

Chinalco closed six inefficient electrolytic aluminium production lines in 2009. The corporation also saved a total of 1.63 million tonnes of standard coal.
