According to him, Washington needs to ensure that Ukraine continues to succeed and that Russia "will fail."

"If we don't, then Putin will be allowed to act with impunity, which will open a Pandora's box of aggression around the world," TASS quoted Blinken as saying.

Earlier it became known that US President Joe Biden will hold a virtual meeting with the G6 leaders on December 7 amid uncertainty about the new assistance of the United States to Ukraine.

Also, Ukrainian Foreign Minister Dmytro Kuleba said at a press conference with his counterpart from the Netherlands Hanke Bruins Slot that he did not expect a slowdown in assistance from Western partners.
