U.S. President Donald Trump said on Thursday he wanted to meet Russian President Vladimir Putin soon to secure an end to the war with Ukraine and expressed a desire to work towards cutting nuclear arms.

In a post to Truth Social, President Trump threatened to hit Russia with tariffs if Vladimir Putin refuses to make a deal on the Ukraine war.

Putin has said repeatedly that he is prepared to negotiate an end to the war, which first began in 2014, but that Ukraine would have to accept the reality of Russian territorial gains, which are currently about 20% of its land. He also refuses to accept Ukraine joining Nato, the military alliance of Western countries.
