Both loans will be issued with an 8% interest rate until 2019.
VTB, Russia's second-largest bank, will receive its loan in two tranches, while Rosselkhozbank has obtained its loan in full.
VTB asked the national development bank for aid in refinancing its $11.4 billion foreign debt in 2008-2009 last week.
"We have to pay off some $2.4 billion of foreign debts before the end of this year," VTB chief Andrei Kostin told reporters in Washington, adding that another $9 billion in foreign debt would have to be paid in 2009.
The Russian government has allocated the national development bank VEB $50 billion from its international reserves to refinance foreign debts of Russian companies and banks.
