A U.S. document on security guarantees for Ukraine is completely ready and Kyiv is waiting for a time and place for it to be signed, President Volodymyr Zelenskiy said on Sunday, indicating that weekend talks with Russia in Abu Dhabi made some progress, Reuters reported. 

"For us, security guarantees are first and foremost guarantees of security from the United States. The document is 100% ready, and we are waiting for our partners to confirm the date and place when we will sign it," Zelenskiy told a news conference during a visit to Vilnius, the Lithuanian capital.

"The document will then be sent for ratification to the U.S. Congress and the Ukrainian parliament," he said, according to Reuters.
