DETROIT — As thousands of General Motors workers await word on more U.S. plant closures, reports that the company plans to import Chinese-made vehicles to the U.S. have created a political problem for the automaker and the White House.

The reports, which GM will neither confirm nor deny, could mean trouble because GM is supported by $15.4 billion in U.S. government loans, largely due to the Obama administration's desire to preserve the company's 90,000 U.S. jobs.

The United Auto Workers charged last week that the Detroit automaker intends to almost double over the next five years the number of vehicles it imports to the U.S. from Mexico, South Korea, China and Japan.

"GM should not be taking taxpayers' money simply to finance the outsourcing of jobs to other countries," Alan Reuther, the union's Washington lobbyist, wrote in a letter to U.S. lawmakers.

The carmaker, which was in danger of running out of cash early this year, faces a June 1 government deadline to cut costs and complete other restructuring measures or go into Chapter 11 bankruptcy protection. It also has requested another $11.6 billion in government loans to make it through this year and faces the prospect that the government will soon be its largest shareholder.

On Wednesday, Shanghai Securities News and other Chinese media reported GM plans to begin exporting vehicles from China to the U.S. within two years, ramping up sales to more than 50,000 by 2014.

GM spokesman Tom Wilkinson in Detroit would not comment on the reports. The White House and Treasury Department did not immediately respond to requests for comment.

"GM is reviewing various options," GM's China office said in a written statement received today. "We are not discussing details of our future portfolio, beyond what we have disclosed in auto shows and our viability plans."

But the report reiterated the company's emphasis on first meeting demand in the Chinese domestic market.

Harley Shaiken, a professor at the University of California at Berkley who specializes in labor issues, said increased overseas production and imports could prove politically tricky for GM.

"The reason is simple — production location is a corporate decision, but when it's on the taxpayer dime, there are different sensitivities, so the notion of billions for a rescue package and offshore production, I think, could be politically combustible," he said.
