HONG KONG — United States officials have torpedoed a Chinese state-backed group’s plan to buy an American electronics company, signaling the Trump administration’s continuing skepticism toward Chinese investment deals, particularly those that involve transferring technological know-how.

Xcerra, a Massachusetts-based provider of equipment for testing computer chips and circuit boards, said this week that it was withdrawing from its $580 million sale to an investment group backed by a Chinese government-controlled fund.

The reason, according to Dave Tacelli, Xcerra’s president and chief executive, was that the deal was not likely to be approved by the Committee on Foreign Investment in the United States, a multiagency Washington panel that operates largely out of the public eye. The committee, known as Cfius, plays an advisory role to the president, but it can effectively block foreign acquisitions of American companies over national security concerns.

“Despite our best efforts to secure approval, it has become evident that Cfius will not clear this transaction,” Mr. Tacelli said. The deal would ultimately have been financed by the China Integrated Circuit Industry Investment Fund, a $21 billion fund that counts several Chinese state-run companies as investors.
