The lower house of the Russian parliament voted Thursday to admit Crimea and the metropolitan region of Sevastopol into the Russian Federation, and President Obama announced new sanctions including penalties aimed at “key sectors of the Russian economy.” …

In Washington, Obama said he was ordering new sanctions against Russia in response to what he called Crimea’s “illegal” secession referendum and Russia’s “illegitimate move” to annex Crimea.

“The United States is today moving . . . to impose additional costs on Russia,” Obama said. He said more senior Russian officials will be subject to sanctions, as well as other individuals and a bank that provide “material support” to the Russian leadership.

Obama added that he signed a new executive order Thursday that gives the United States authority to impose sanctions not just on individuals but on key sectors of Russia’ economy. He did not immediately elaborate on which sectors might be targeted, but he noted that the moves “could also be disruptive to the global economy.”
