MOSCOW, Jan 22 (Reuters) - The United Nations has opened a bank account with a non-sanctioned Russian lender to allow for transactions in roubles, Russia's Sovcombank said on Monday.

The name of the bank was not specified.

Sovcombank, one of Russia's 13 "systemically important" credit institutions, has applied to the U.S. Treasury for a licence to make membership payments to a U.N. climate funding programme while its activities are blocked by U.S. sanctions.

The U.N. did not immediately respond to a request for comment. (Reporting by Elena Fabrichnaya; Writing by Alexander Marrow; Editing by Jan Harvey)
