The United States hit Russia on Friday with a new round of economic听sanctions, levying penalties on Russia's largest bank and expanding financing restrictions on major energy and defense companies.

The new Russia sanctions include five major energy firms and are intended to "shut down" Russia's deepwater, shale, and Arctic exploration, according to one senior US official, as reported by Reuters.

"We will deepen and broaden sanctions in Russia鈥檚 financial, energy, and defense sectors," President Obama said in , a day ahead of the Russia sanctions rollout. "These measures will increase Russia鈥檚 political isolation as well as the economic costs to Russia, especially in areas of importance to President Putin and those close to him."

The听sanctions听were imposed in coordination with the European Union, which unveiled its own package of penalties hours earlier. Officials said the parallel penalties are aimed at punishing Russia for deepening its provocations in Ukraine, including sending forces and weaponry across the border.

The penalties were levied despite a fragile cease-fire between Ukraine and pro-Russian separatists. However, officials said the sanctions听could be rolled back if the separatists and Russia implement the agreement in good faith.

A prime target of the new听sanctions听is Sberbank of Russia, the country's largest financial institution. The bank accounts for approximately a quarter of Russian banking assets and a third of its banking capital, according to the Obama administration.

Sberbank, along with five other previously听sanctioned听Russian banks, will now face restrictions if it seeks debt financing of longer than 30 days. The European Union issued similar restrictions Friday, effectively locking the Russian banks out of any long-term debt financing from the West.

The U.S. was also prohibiting U.S. entities from exporting goods services or technology to help Russian energy companies with the exploration of production of potentially lucrative oil projects. The听sanctioned听Russian companies include Gazprom, the world's largest extractor of natural gas, and Rosneft, an oil company owned by the Russian government.

The penalties could impact major U.S. companies that have partnered with key players in Russia's energy industry.

Also targeted by the U.S.听sanctions听are five Russian defense companies that produce weapons, ammunition and anti-aircraft systems.
