United States President Donald Trump has backed a powerful new bipartisan bill aimed at punishing countries that continue to buy Russian oil, according to Republican Senator Lindsey Graham. The proposed legislation would give Trump the authority to impose tariffs of up to 500 percent on imports from nations doing business with Russia’s energy sector. China and India are expected to be among the most impacted.

U.S. President Donald Trump has claimed that Indian Prime Minister Narendra Modi assured him India would stop buying Russian oil. Trump called this a “big step” in efforts to pressure Moscow to end the Ukraine war and said he would now seek China’s cooperation as well.
