President Vladimir Putin said Russia hasn’t achieved its objectives in Ukraine yet, adding in an interview with former Fox News host Tucker Carlson that he would consider negotiations if the U.S. stops supplying weapons to Kyiv.

“We haven’t yet achieved our goals”, Putin said in the Feb. 6 interview in Moscow.

“We’re conveying to the U.S. leadership that if you really want to stop military action, then you need to stop supplying weapons, then it will all be over in a few weeks and we’ll be able to discuss some terms,” Putin said.

In the interview, Putin suggested a deal can be reached to release jailed U.S. journalist Evan Gershkovich, hinting that the Wall Street Journal reporter could be returned in a prisoner swap.

“We have certain conditions that are being discussed through channels between special services. I believe an agreement can be reached”, - Putin said.

In response to questions from Carlson, Putin also reiterated charges against Gershkovich that have been roundly rejected by the Wall Street Journal and the U.S. government, which says the reporter was “wrongfully detained” by Moscow.

Most of Carlson’s two-hour conversation with the Russian leader was devoted to repetitions of Putin’s long-standing criticisms of the U.S. and its allies, and his controversial views on the history of Ukraine-Russia relations.
