According to his post on Truth Social, he has sent the appeal as a letter to all NATO countries - "and the world". He demands that the oil import cease, and that NATO countries follow his line and impose the same sanctions as the USA.
"As you know, NATO's commitment to winning has been far from 100 percent and some countries' import of Russian oil is shocking! It weakens the negotiating position against Russia considerably", Trump writes.
The war in Ukraine will end "quickly" if NATO "does what I say", he continues in the post.
"If you don't, you're just wasting my time as well as the USA's time, energy and money."
Sanctions against China
Trump also wants NATO countries to impose massive punitive tariffs against China, which he says has "a strong grip" on Russia.
"I believe that this plan, together with NATO, as a group, introducing 50- to 100-percent import duties against China, which will be removed when the war between Russia and Ukraine is over, will greatly contribute to stopping this deadly but absurd war."
The President repeats that it is not "Trump's war" and places the responsibility on former President Joe Biden and Ukraine's President Volodymyr Zelenskyj. He does not mention Vladimir Putin.
Not the first time
Trump has several times threatened to impose new sanctions against Russia, most recently last week when Russia attacked Ukraine with what is described as the largest Russian drone swarm so far. But so far, he has not made the threats a reality, to Kyiv's frustration.
The Western world's imports from Russia have decreased significantly since Russia's full-scale invasion of Ukraine in 2022. But the taps are not completely turned off.
In the first quarter of 2021, 29 percent of the EU's oil imports came from Russia, which was by far the largest single exporting country of the commodity to the union. Four years later, that figure is 2 percent, according to the EU's statistical office Eurostat.
On the other hand, a large part of the union's imports of, among other things, natural gas still comes from Russia.
Welcome
Foreign Minister Maria Malmer Stenergard (The Moderate Party) welcomes Trump's move.
"This is something we now need to analyze together with allies and partners. In the EU, work is underway on a 19th sanctions package, where the government is pushing for further sanctions against, among other things, Russian energy revenues. The government also supports the phasing out of Russian energy within the EU, not least fossil fuels, as soon as possible", she says in a written statement to TT.
