By Florence Tan, Siyi Liu, Chen Aizhu and Nidhi Verma SINGAPORE/NEW DELHI (Reuters) - Chinese and Indian refiners are scouring the globe for supplies of crude as fresh U.S. sanctions on Russian producers and tankers curb shipments to Moscow's top customers,

Russian oil exports will be hurt severely by the new sanctions, pushing China and India, the world’s top and third-largest oil importers respectively, to source more crude from the Middle East, Africa and the Americas, which will boost prices and shipping costs, traders and analysts said.

India intends to abandon oil tankers that have been sanctioned by the United States because of their role in transporting goods for Russia, which is another example of the impact of Washington's measures on the global oil market.
