“In the 21st century nations cannot and we will not allow them to redraw borders by force. There are the ground rules. Russia has violated these gound rules and continues to violate them. Today, Russia is occupying sovereign Ukrainian territory. Let me be crystal clear: the United States does not, will not, never will recognize Russia's attempt to annex Crimea,” Biden said, drawing load applause from the Ukrainian lawmakers.

“There is no justification. Then as Russia continues to send its thugs, its troops, its mercenaries across the border. Russian tanks and missiles still fill the Donbass. Separatist forces are organized, commanded and directed by Moscow. So, the United States will continue to stand with Ukraine against Russian aggression. We are providing support to help and train and assist your security forces,” said Joe Biden.

Biden also talked about cooperation with the EU.

“America and Europe now stand together, united in our commitment to impose tough economic sanctions on Russia. And while Russian aggression persists, the cost imposed on Moscow will continue to rise. There can be no sanctions relief unless and until Russia meets all - all of its commitments,” Biden said.

Joe Biden also stressed that the responsibility for the fate of Ukraine lies with the Ukrainian government, so the entire world is watching it working.
