Russia's largest state-owned bank OAO Sberbank (SBER.RS) will sell its stake in General Motors Corp.'s (GM) German unit Adam Opel GmbH, potentially to a Russian strategic investor, Sberbank's Chief Executive German Gref said Thursday.

Gref said that Sberbank is not planning on becoming a strategic investor in Opel. He added that the deal - which the bank is conducting together with Austrian-Canadian car parts maker Magna International Inc. (MGA) should be fully completed by the autumn.

Both partners will commit some EUR500 million that will be divided proportionally to their stakes in Opel, Gref said.

"Proportionally, we have 35%, they have 20%," Gref said. The former economic minister also said that the Opel deal includes Russian rights to Chevrolet, the best selling foreign brand in the country.
