THE BURNED OVER DISTRICT

And they know where to get it, which is why they are setting up shop in Detroit to tap into American automobile workers and know how.

Chinese-owned companies are investing in American businesses and new vehicle technology, selling everything from seat belts to shock absorbers in retail stores, and hiring experienced engineers and designers in an effort to soak up the talent and expertise of domestic automakers and their suppliers.

While starting with batteries and auto parts, the spread of Chinese business is expected to result eventually in the sale of Chinese cars in the United States.

“The Chinese are well behind the Japanese when they hit our shores 30 years ago,” said David E. Cole, a founder of the Center for Automotive Research in Ann Arbor, Mich. “They lack the know-how, and they’re coming here to get it.”

As businesses sprout up with little fanfare, Chinese companies seem to be trying to avoid the type of public opposition experienced by the Japanese automakers Toyota and Honda in the 1980s, when the sudden influx of foreign cars competing head-on with cars from General Motors, Ford and Chrysler was perceived as a threat to American jobs.

In contrast to the Japanese, Chinese auto companies are assiduously avoiding the spotlight. Last year, the biggest carmaker in China, Shanghai Automotive Industries, opened new offices in suburban Detroit without any publicity, which is almost unheard-of in an industry that thrives on media coverage.

But China’s growth in the American auto industry is drawing notice in Washington. Last year, the Obama administration filed a complaint with the World Trade Organization that China’s government was unfairly subsidizing the production of some parts shipped to America. And the country’s inroads into American-made batteries and electric vehicles have drawn scrutiny because that sector of the industry has been heavily subsidized by the United States government.

Pretty sneaky of them to hire American engineers who have been laid off by US companies to make way for cheaper foreign engineers.
