BRUSSELS, May 29 (Reuters) - Germany assured other European governments at talks on Friday that proposed 1.5 billion euro ($2.1 billion) bridge financing for General Motors GM.N unit Opel would benefit all its European plants.

The German offer has raised suspicions among EU neighbours that any rescue plan put together for Opel as its giant U.S. parent heads towards bankruptcy would favour German jobs at the expense of those at Opel plants elsewhere in Europe.

But EU ministers emerged from two hours of talks in Brussels stressing that any deal must stick to EU state aid rules and that German aid would benefit Opel activities across the bloc.

"What we are doing is designed for a positive effect for all of Europe. I believe that was clearly understood today," German Deputy Economy Minister Peter Hintze told reporters.

Belgian Economy Minister Vincent Van Quickenborne said: "It is clear, stated by the Germans, that the bridge loan will be fed toward all existing plants, and not just to the German plants."

Earlier, sources close to the negotiations over the future of Opel said Canadian auto parts group Magna (MGa.TO: Quote, Profile, Research) had reached an initial deal with GM to invest in the company, boosting the chances of Germany and the United States agreeing on arrangements that would allow Opel to survive.
