President Donald Trump said on 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 per cent to 100 per cent 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 per cent” and the purchase of Russian oil by some members of the alliance is “shocking.” As if speaking to them, he said, “It greatly weakens your negotiating position and bargaining power over Russia.”
