Future foreign investment in the United States is unlikely to be chilled by the unraveling of a controversial $2.2 billion deal involving a Chinese company that several members of Congress warned could damage U.S. national security, according to private-sector sources tracking the issue.

“We don’t see it as a sign of things to come in terms of chilling investment,” said Nancy McLernon, vice president of the Organization for International Investment. “No one I work with feels that way at all.”

Rep. Thaddeus McCotter (R-Mich.), who introduced a resolution critical of the deal, described its collapse as a victory for national security. “We must remain even more vigilant to ensure American national security is not for sale; and to stop communist Chinese stealth assaults on our national security,” he said in a statement.

McLernon and Ed Rice, chairman of the Coalition for Employment through Exports, however, both said the 3Com deal was unique in that it raised specific security issues appropriate for review by the Committee on Foreign Investment in the United States (CFIUS), the inter-agency body considering the 3Com deal.

Rules governing CFIUS reviews were overhauled after the body’s controversial decision to approve a deal that allowed a United Arab Emirates company to take control of a business managing a number of U.S. ports. That led to fears, which the failed 3Com deal could fuel, that the U.S. was turning against foreign investment.

“There appears to be a real national security issue involving one aspect of 3Com’s interactions with our government,” Rice said.

3Com’s Tipping Point unit sells security software to the Pentagon, and this part of the company’s business drew scrutiny from CFIUS, which apparently attempted to impose conditions on the deal. In withdrawing their request for federal review, Bain officials said they were disappointed not to reach an agreement with CFIUS.

Huawei’s ties to China’s government were another factor for congressional scrutiny. Huawei, the largest telecommunications supplier in China, was launched by a former officer of China’s military.

“I don’t think this outcome has broader implications for China and for that matter India and other countries interested in investing in the U.S. tech sector,” Rice said.

National Foreign Trade Council Bill Reinsch, however, said Chinese firms could have second thoughts about going into business with U.S. firms. “I think it will have a chilling effect on the Chinese,” he said.

Sens. Chris Dodd (D-Conn.) and Richard Shelby (R-Ala.), who head the committee with jurisdiction over CFIUS, released a statement Wednesday that said the withdrawal of the 3Com deal shows that new CFIUS rules are working effectively. The announcement demonstrates that “federal agencies are taking appropriate action to protect our national security,” the statement said.

Commerce Undersecretary Christopher Padilla declined to comment on the decision because of legal restrictions. He said CFIUS would “continue to monitor and engage appropriately if need be going down the road.”
