WASHINGTON — President Donald Trump said Saturday he believes the Russia-Ukraine war would end if all NATO countries stopped buying oil from Russia and placed tariffs on China of 50% to 100% for its purchases of Russian petroleum.

Trump posted on his social media site that NATO’S commitment to winning the war “has been far less than 100%” and the purchase of Russian oil by some members of the alliance is “shocking.” As if speaking with NATO members, he said: “It greatly weakens your negotiating position, and bargaining power, over Russia.”

Since 2023, NATO member Turkey has been the third largest buyer of Russian oil, after China and India. according to the Centre for Research on Energy and Clean Air. Other members of the 32-state alliance involved in purchasing Russian oil include Hungary and Slovakia.

Trump’s post arrives after the recent flight of multiple Russian drones into Poland, an escalatory move by Russia as it was entering the airspace of NATO ally. Poland shot down the drones, yet Trump played down the severity of the incident and Russia’s motives by saying it “could have been a mistake.”

While Trump as a candidate promised to end the war quickly, he has yet to hit the pressure points needed to end the violence and has at times been seen as reluctant to confront Russian President Vladimir Putin. Congress is currently trying to get the U.S. president to back a bill toughening sanctions, after Trump last month hosted Putin in Alaska for talks that failed to deliver on progress toward peace.

Trump in his post said that a NATO ban on Russian oil plus tariffs on China would “also be of great help in ENDING this deadly, but RIDICULOUS, WAR.”

The president said that NATO members should put the 50% to 100% tariffs on China and withdraw them if the war that launched with Russia’s 2022 invasion of Ukraine ends.

“China has a strong control, and even grip, over Russia,” he posted, and powerful tariffs “will break that grip.”

The U.S. president has already placed a 25% import tax on goods from India for its buying of Russian energy products.

In his post, Trump said responsibility for the war fell on his predecessor, Democrat Joe Biden, and Ukrainian President Volodymyr Zelenskyy. He did not include in that list Putin, who launched the invasion.

Trump’s post builds on a call Friday with finance ministers in the Group of Seven, a forum of industrialized democracies. During the call, U.S. Trade Representative Jamieson Greer and Treasury Secretary Scott Bessent called on their counterparts to have a “unified front” to cut off “the revenues funding Putin’s war machine,” according to Greer’s office.
