The announcement came after the US Commerce Department launched the investigations on Tuesday covering more than $600 million worth of imports of common alloy aluminum sheet from China.

Wang Hejun, head of the trade remedy and investigation bureau at the Ministry of Commerce, said such anti-dumping duty investigation against the aluminum sheet China exports was the first time in 25 years that was self-initiated by the US Department of Commerce instead of the local industrial association.

"It is a rare case in the history of international trade and has sparked strong dissatisfaction in China," he said.

"The aluminum industries in the two countries are complementary to each other and the trade of such products are two-ways," Wang said. "Disturbing normal trade activities of aluminum will harm interests of both sides."
