The United States slapped tougher new sanctions against Russia on Friday, including measures against Russia's largest bank——several state-owned defense technology companies and five energy companies.

In addition to hitting Sberbank with new prohibitions, the Treasury Department said it would imposes sanctions on the exportation of goods and services connected to Gazprom, Gazprom Neft, Lukoil, Surgutneftegas and Rosneft. The U.S. has also tightened its previous restrictions on debt financing from 90 days to 30 days for five other banks.
