Crude oil futures ended lower on Friday on profit booking following yesterday's surge, which came after the Trump administration announced sanctions on Russia's two largest oil companies.  U.S. President Donald Trump hit Russia’s Rosneft and Lukoil with sanctions on Thursday to pressure Russian President Vladimir Putin to end the Ukraine war. The two companies together account for more than 5% of global oil output. Meanwhile, private reports said the sanctions prompted Chinese state oil majors to suspend Russian oil purchases in the short term. Refiners in India, the largest buyer of seaborne Russian oil, are set to sharply cut Russian crude imports.
