Faced with the growing theft of U.S. trade secrets, the White House said on Wednesday it was stepping up diplomatic pressure and mulling tougher laws to stem the threat to American businesses and security from China and other nations.

The plan includes working with like-minded governments to put pressure on bad actors, using trade policy tools, increasing criminal prosecutions and launching a 120-day review to see whether new U.S. legislation is needed.

“A hacker in China can acquire source code from a software company in Virginia without leaving his or her desk,” U.S. Attorney General Eric Holder said at a White House event to unveil the strategy.

Although the White House report did not cite China by name, many see the Asian giant as the main threat. A study released this week by a private security firm accused the Chinese military of orchestrating numerous cyber attacks against U.S. businesses, a charge Beijing has denied.

The Obama administration said its strategy aims to counter what Holder called “a significant and steadily increasing threat to America’s economy and national security interests.”

“As new technology has torn down traditional barriers to international business and global commerce, they also make it easier for criminals to steal secrets and to do so from anywhere, anywhere in the world,” Holder said.

Last week, Representative Dutch Ruppersberger, the top Democrat on the House of Representatives Intelligence Committee, said U.S. companies suffered estimated losses in 2012 of more than $300 billion due to theft of trade secrets, a large share due to Chinese cyber espionage.

The White House report listed 17 cases of trade-secret theft by Chinese companies or individuals since 2010, far more than any other country mentioned in the report.

U.S. corporate victims of trade-secret theft have included General Motors, Ford, DuPont, Dow Chemical, Motorola, Boeing and Cargill. A target company can see the payoff from research investment evaporate as a result of corporate espionage and lose market position, competitive advantage and efficiencies.
