MOSCOW, May 25 - The Ukraine-related risks of Sberbank and other Russian banks total $25 billion, a top Sberbank executive said on Saturday.

"The $25 billion is a figure that includes not only loans but also our investments, our guarantees," first deputy chief executive Maxim Poletayev told reporters.

He praised Metinvest, Ukraine's largest steel producer, for servicing its Sberbank loans accurately.
