The German economics ministry may send a team to the U.S. for negotiations over the future of General Motors Corp.'s (GM) German unit Adam Opel AG if bidders' plans for the German carmaker are reasonable, a ministry spokeswoman told Dow Jones Newswires Monday.

"If the concepts that will be presented until Wednesday appear to be reasonable, the federal ministry of economics will send a negotiation team to the U.S.," said ministry spokeswoman Beatrix Brodkorb. "The economics minister keeps the option open to possibly intervene in the negotiations personally."
