MOSCOW - Russia's deputy prime minister laughed off President Obama's sanction against him today asking "Comrade @BarackObama" if "some prankster" came up with the list.

The Obama administration hit 11 Russian and Ukrainian officials with sanctions today as punishment for Russia's support of Crimea's referendum. Among them: aides to President Vladimir Putin, a top government official, senior lawmakers, Crimean officials, the ousted president of Ukraine, and a Ukrainian politician and businessman allegedly tied to violence against protesters in Kiev.

It remains to be seen whether the sanctions will dissuade Russia from annexing Crimea, but one an early clue that they will not be effective came just hours later when President Putin signed a decree recognizing Crimea as an independent state, perhaps an early step towards annexation.

U.S. official have warned of additional sanctions for Russian action, hoping it will deter Russia from any further aggression towards Ukraine, but it didn't appear to upset the often outspoke Deputy Prime Minister Dmitry Rogozin.

Rogozin, a friend of actor Steven Seagal, took to Twitter to tweak Obama, tweeting he thinks "some prankster" came up with the sanctions list

In a later tweet addressed to "Comrade @BarackObama," he asked, "what should do those who have neither accounts nor property abroad? Or U didn't think about it?"

Another Russian on the sanctions list, Vladislav Surkov, also seemed unconcerned.

Surkov, a top Putin ideologue often called the Kremlin's grey cardinal, reportedly told a Russian newspaper, "It's a big honor for me. I don't have accounts abroad. The only things that interest me in the U.S. are Tupac Shakur, Allen Ginsberg, and Jackson Pollock. I don't need a visa to access their work. I lose nothing."

Here's who gets hit with the sanctions:

U.S. officials said that, among the sanctioned individuals were the "key ideologists and architects" of Russia's Ukraine policy, while adding that some of the Russian officials were included in the list for their role in curbing "human rights and liberties" in Russia.

The sanctions freeze any assets under American jurisdiction and prevent American banks from doing business with the named individual, essentially freezing them out of the international banking system. The sanctions also impose a ban on their travel to the United States. Separately, but in coordination with the White House, the European Union announced sanctions today on 21 individuals that it plans to name later. U.S. officials told reporters that the American and European lists "overlapped" in some area, but declined to say how.

While some of the sanctioned officials are bold faced names, the White House move is unlikely to affect Russia's decision making with regard to Crimea's bid to join the Russian Federation. Russia's stock market actually improved on the news that so few officials were included on the list. U.S. officials warned that, if Russia does go ahead with annexation of Crimea, additional penalties will follow, with more, harsher measures to come if Russia attempts to enter eastern Ukraine.
