US President Donald Trump has stated he is prepared to impose tougher sanctions on Russia, contingent upon NATO countries stopping their purchases of Russian oil.

In a post on his Truth Social platform, he said he was ready to do major sanctions on Russia once NATO nations had agreed, and started, to do the same thing.

Trump has repeatedly threatened tougher measures against Moscow but has so far failed to take any action when the Kremlin ignored his deadlines and threats of sanctions.

He described the purchases of Russian oil as shocking and suggested that NATO impose 50 to 100% tariffs on China, claiming it would weaken its strong control over Russia.

In what he referred to as a letter to NATO nations, Trump stated: I am ready to 'go' when you are. Just say when? He emphasized that the purchase of Russian oil has severely weakened the negotiating position and bargaining power of NATO countries against Russia.

Trump further claimed that halting Russian energy purchases alongside substantial tariffs on China would be crucial in resolving the ongoing conflict and help in ending the war.

Since Russia's invasion of Ukraine, Europe’s reliance on Russian energy has decreased, going from about 45% last year to an expected 13% this year. However, Trump continues to press for a more rapid cessation of purchases.

This announcement comes amid heightened tensions after several Russian drones reportedly entered Polish airspace, though Moscow downplayed the incident and denied any plans to target Polish facilities.

NATO countries including Denmark, France, and Germany are increasing military readiness in response to the ongoing conflict, while Ukrainian President Volodymyr Zelensky has called for an immediate halt to European energy dealings with Russia.

As European nations have spent approximately €210 billion on Russian oil and gas since 2022, supporting the war effort, the EU has committed to cease these purchases by 2028, with the US urging for a quicker phase-out.

Trump's message appears targeted not just at NATO members in Europe, but also at countries like Turkey, which have maintained stronger ties with Russia.

The ongoing geopolitical landscape continues to evolve as demands for sanctions and support for Ukraine intensify.
