Beijing on Tuesday criticized new US controls on exports to China of technology with possible military uses, rejecting them as a threat to cooperative relations and efforts to shrink the swollen Chinese trade surplus.

"The Chinese side expresses extraordinary regret and great concern about this," the Commerce Ministry said on its Web site. It said Beijing reserved the right to take unspecified "corresponding measures" in response.

The US rules announced Friday are meant to deny China's military access to technology that might aid its modernization. They impose new end-use controls on goods including lasers, telecommunications equipment and navigation systems.

"The Chinese side believes the US side's insistence on issuing these rules without fully hearing China's opinions is inappropriate, and violates the cooperative spirit," the Commerce Ministry statement said.

The rules "will damage the Chinese side's effort to expand imports from the United States," the statement said. It appealed to Washington to keep in mind the benefits from developing US-Chinese trade in high-tech goods.

The new controls reflect Washington's unease over China's military strength even as American officials press Beijing to lower barriers to imports of US goods.

The regulations also are intended to make it easier for US companies to sell semiconductors, chemicals and other technology to some Chinese customers that undergo advance screening.
