US President Donald Trump is threatening tariffs on other countries that buy Russian oil, in an attempt to pressure Moscow to end the war in Ukraine. But the United States and Europe themselves are still doing billions of dollars in trade with Russia.

Former Russian President Dmitry Medvedev taunted European leaders early Monday, accusing them of having "failed to outplay" U.S. President Donald Trump.

WASHINGTON (AP) — Ukraine’s future could hinge on a hastily assembled meeting Monday at the White House as Ukrainian President Volodymyr Zelenskyy brings with him an extraordinary cadre of European leaders to show U.S. President Donald Trump a united front against Russia.

The upcoming summit between President Donald Trump and his counterpart Vladimir Putin is being used by the Kremlin to divide the U.S. from Europe over the war in Ukraine, according to analysis.

The leaders of Germany, France, Britain and other supporters of Ukraine have come together in exceptional ways to help sway the U.S. president.

Russian troops currently control about 20% of Ukrainian territory, but the Ukrainian constitution forbids giving up territory or trading land.

Treasury Secretary Scott Bessent urged European nations to be prepared to get on board with higher tariffs on China and other nations that buy Russian energy, lamenting that he got a cool response when he floated the idea at a Group of Seven meeting earlier this year.

Russian Foreign Minister Sergei Lavrov said on Tuesday that it was clear at Friday's U.S.-Russia Alaska summit that U.S. President Donald Trump and his team sincerely wanted to achieve a long-term and sustainable peace in Ukraine.
