Reuters reported that Hong Kong listed shares of Aluminum Corporation of China Limited were suspended ahead of the release of Q3 earnings because of concern the state company had disclosed information ahead of the scheduled release later in the day.

A company spokeswoman said that the H-shares were suspended because of strong gains in the company's American Depositary Receipts. Also, there have been media reports that the company's third-quarter earnings would show strong growth. The stock exchange suspended trade because of worries over an information leak.

Mr Luo Jianchuan president of Chalco said that its shares had been suspended pending the release of an announcement in relation to the company's Q3 results. It expected to post strong Q3 results on rising aluminum prices and improving operating conditions earlier this year.

Mr Luo also cautioned in the report that a weak US economic recovery and the severity of the European debt crisis would pressure aluminum prices amid rising costs which could squeeze Chalco's profitability. China's monetary policy tightening measures had also impacted financing conditions in the mainland, making it more difficult for Chalco to obtain financing. Component companies may encounter cash flow problems if prices continued to drop.
