(QHA) -

The United States Treasury Department has sanctioned Moscow-registered Russian National Commercial Bank (RNCB) in Crimea.

Ukraine's biggest banks left Crimea following its unification with Russia a year ago. As Russian little-known banks came to Crimea, RNCB ranked by Interfax news agency as Russia's 142nd largest by assets, was the first Russian bank to open its doors in Crimea after the region joined Russia.

RNCB said the sanctions "do not pose a threat to its current activities" and "at present, RNCB has no assets in the United States."

Russia's biggest lender, state-owned Sberbank, declared the largest bank in Russia and Eastern Europe, and the third largest in Europe as for 2012, which used to operate in Crimea for years, withdrew from Crimea immediately after the unification and gave RNCB its former network in the region.

The bank was sanctioned by the European Union last year.
