U.S. President Donald Trump is pushing China and India to stop buying oil from Russia and helping fund the Kremlin’s war against Ukraine. Trump is raising the issue as he seeks to press Russian President Vladimir Putin to agree to a ceasefire.

"If the U.S. is bent on imposing tariffs, China will fight to the end, and this is China's consistent official stance," said Tu Xinquan, director of the China Institute for WTO Studies at the University of International Business and Economics in Beijing. WTO is the acronym for the World Trade Organization.
