The European Commission Wednesday said it will convene a meeting of European economy ministers to discuss matters around the sale of U.S. automaker General Motors Corp.'s (GM) Opel unit.

"We are organizing a meeting with the ministers of all the members states," said the commission's industry spokesman Ton Van Lierop. He wasn't able to confirm when the meeting would take place, but said it would be convened at the "shortest notice" for information exchange purposes.

The commission was called to action by the Belgian state which earlier Wednesday sent a letter to the commission, asking it to ensure any resolution to the future of Opel is fair to all European countries where GM has operations.

"We are now faced with the involvement on the European side of only one government in this decision-making process," the letter said, referring to the German government's recent talks with GM and potential partners.
