President Donald Trump threatens major sanctions on Russia, but only if NATO nations first stop buying Russian oil and end their dependence on Moscow’s energy.

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.

US president said he is ready to impose further sanctions on Russia, but only if all NATO countries stop buying Russian oil, a huge source of income for Putin.

The aid will be the first use of the Prioritized Ukraine Requirements List (PURL), a mechanism developed by NATO members and the United States to coordinate and fund Kyiv's most urgent battlefield needs.

Trump will meet King Charles III at Windsor Castle and hold talks with Prime Minister Keir Starmer at Chequers.

In a letter sent to all NATO nations on Saturday, Trump had said that some members' continued imports of Russian oil had "greatly weakened" the alliance's leverage.

President Trump attempted to give Vladimir Putin another pass after Russia sent drones deep into Polish territory. The incident comes a week after Donald Trump met with Polish President Karol Nawrocki at the White House.
