US President Joe Biden and Ukrainian President Volodymyr Zelenskyy signed a security agreement on Thursday during the Group of Seven (G7) summit, sending what they described as a message of unified opposition to Russian President Vladimir Putin.

“He cannot wait us out,” Biden said. “He cannot divide us.”

Zelenskyy said the agreement demonstrated the “credibility of American support for our Ukrainian independence.”

"Today is a truly historic day. We have signed the strongest agreement between Ukraine and the US since our independence," the Ukrainain leader said.
