"All the companies are looking to expand their presence in China and many of them already had facilities," he told reporters. "The opportunities are stunning in China."
Locke said Sunday in Hong Kong that "concrete proposals" on the export control regime could be expected within the next several months.
"Various reports and studies have indicated that some restrictions of export control have inhibited U.S. companies' sales of emerging technologies," he said. "We believe that some of these restrictions we have on the U.S. companies make absolutely no sense."
Locke has also made stops in Shanghai and Beijing. He will join U.S. Secretary of State Hillary Clinton, U.S. Treasury Secretary Timothy Geithner and other cabinet officials for the Second China-U.S. Strategic and Economic Dialogue scheduled for Monday and Tuesday in Beijing.
The dialogue will include issues of mutual concern including international and regional security, energy, trade and health care, he said.
