Ukrainian President Serenski said in a speech to the US Congress on the evening of the 21st local time that US assistance to Ukraine was "crucial". That night, Zelensky delivered a speech in English. Vice President Harris of the United States, senior officials of Biden's government, and members of both houses of Congress were present. In his speech, Zerensky thanked the United States for providing economic and military assistance to Ukraine and said that such assistance was "crucial" to Ukraine. Zelensky also said that the US assistance to Ukraine is actually "an investment in global security", and Ukraine "will use these assistance responsibly". He hoped that the United States would continue to provide support to Ukraine. Zelensky also said that Ukraine "needs peace". Ukraine has prepared a peace proposal, which was also supported by US President Biden. Zelensky also called on the US side to take more sanctions against Russia. Zelenski also said that he expected that next year would be the "turning point" of the conflict. On the same day, President Biden of the United States met with visiting Ukrainian President Zolensky at the White House. At the press conference after the meeting, Biden once again condemned Russia's military action against Ukraine and expressed support for Ukraine. US Secretary of State Antony Blinken announced on the same day that the United States would provide a total of 1.85 billion dollars in military assistance to Ukraine, including the Patriot air defense missile system provided to Ukraine for the first time. Since the conflict between Russia and Ukraine in February this year, the United States has taken several rounds of sanctions against Russia, including sanctions against individuals such as Russian President Vladimir Putin, excluding some Russian banks from the payment system of SWIFT, and canceling normal trade relations with Russia.
