China is the largest buyer of Russian energy, followed by India. In the third place stands Turkey who is a NATO member. Hungary and Slovakia are other members of the 32-state alliance that also purchase oil from Russia.

US President Donald Trump on Saturday said that the Russia-Ukraine war would end if NATO countries stopped buying Russian oil. He also threatened to impose 50-100 per cent tariffs on China for its purchase of petroleum from Russia.

Taking to Truth Social, Trump wrote that the purchase of Russian oil by members of NATO is "shocking". Addressing NATO, he said, "It greatly weakens your negotiating position, and bargaining power, over Russia". He also accused NATO and said that their commitment to win the war "has been far less than 100%".
