Trump urges Nato countries to stop buying Russian oil to end Ukraine war

Donald Trump has said the Russia-Ukraine war would end if all Nato countries stopped buying oil from Russia, and also placed tariffs on China of 50% to 100% for its purchases of Russian petroleum.
The US president 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 is “shocking”.
