Three European Commissioners Tuesday called on governments to fully respect the rules on state aid in the restructuring of General Motors Corp.'s (GM) European activities.

The commissioners -Guenter Verheugen for enterprise and industry, Neelie Kroes for competition, and Vladimir Spidla for employment and social affairs - called for a "coordinated action and full respect of E.U. state aid and internal market rules in the GM Europe restructuring," in a statement.

GM's European operations include German-based Adam Opel, with plants in other E.U. countries. Governments are concerned that any restructuring would lead to plant closures and job losses.
