U.S. President Joe Biden on Tuesday announced "the first tranche" of sanctions against Russia after Moscow deployed troops in the Lugansk and Donetsk regions.
Russian President Vladimir Putin on Monday signed two decrees, recognizing "the Lugansk People's Republic" and "the Donetsk People's Republic" as "independent and sovereign" states, and later ordered troops to enter the regions to conduct peacekeeping operations.
Lugansk and Donetsk declared independence following a vote during the height of armed conflict with Kiev in 2014. Ukraine refused to recognize their self-proclaimed status.
Calling Russia's move "the beginning of a Russian invasion of Ukraine," Biden said in remarks delivered from the White House that his administration will impose sanctions on two Russian financial institutions - the VEB and the country's military bank -- as well as on Russia's sovereign debt and three individuals.
He explained that the measure "means we've cut off Russia's government from Western financing. It can no longer raise money from the West and cannot trade in its new debt on our markets or European markets either."
Biden also mentioned the suspension of the Nord Stream 2 natural gas pipeline project between Russia and Germany, which Berlin announced earlier in the day. Additional sanctions will be followed if the situation escalates, he said.
The president also announced movements of U.S. troops to the three Baltic states of Estonia, Latvia and Lithuania, all of which are members of the North Atlantic Treaty Organization (NATO) and share borders with Russia.
Biden said that the United States has "no intention of fighting Russia" but will "abide by" its commitments to NATO.
Following Moscow's recognition of Lugansk and Donetsk, Biden signed an executive order on Monday banning Americans from doing businesses in the two regions.
On Tuesday, U.S. Secretary of State Antony Blinken called off a meeting with Russian Foreign Minister Sergey Lavrov scheduled for Thursday.
During a joint press briefing at the State Department with Ukrainian Foreign Minister Dmytro Kuleba, Blinken said it makes little sense to hold a meeting with Lavrov following the Russian moves.
