“This decision represents a complete rejection of Russia’s obligations under the Minsk agreements, directly contradicts Russia’s alleged commitment to diplomacy, and constitutes a clear attack on Ukraine’s sovereignty and territorial integrity,” Blinkin said in a statement.
“Russia’s decision is another example of President Putin’s blatant disrespect for international law and norms,” he said.
Washington has also repeatedly said that the Nord Stream 2 gas pipeline, which connects Russia with Germany by sea, will not be operational if Moscow attacks Ukraine.
The US presidency also released a 30-minute phone call between Biden, French President Emmanuel Macron and German Chancellor Olaf Schulz after Putin’s speech.
Biden has led a coalition of European countries and other allies of the United States to assemble a package of what they see as crippling economic sanctions against Russia in the event that troops massed along the Ukrainian border launch an attack.
While the Kremlin has denied any plans for an invasion for weeks, it has simultaneously amassed a huge force of troops and heavy weapons on three fronts in Ukraine.
Soon after recognizing their independence, Putin ordered troops to be sent to the two breakaway regions as part of a “peacekeeping” operation.
