Russia's Federal Financial Monitoring Service said it has not been contacted by Danish and Estonian financial crime authorities regarding money laundering investigations into Danske Bank A/S' Estonia branch, Reuters reported.

Rosfinmonitoring said it was ready to assist should it receive requests through official channels to look into the matter.

Up to $30 billion of Russian and ex-Soviet funds passed through Danske's Estonian branch in 2013 alone, according to a report commissioned by the Danish lender, which has in recent months faced intense regulatory scrutiny over those transactions.

Meanwhile, Danish Business Minister Rasmus Jarlov told the newswire that the country is in contact with U.S. authorities over the Danske scandal. He also noted the Danish Financial Supervisory Authority should have been more critical of the data provided to it by the bank, instead of trusting them without an inquiry, according to a separate Reuters report.
