Exclusive-US sanctions on China refiners over Iran oil disrupt operations, sources say

SINGAPORE (Reuters) -Recent U.S. sanctions on two small Chinese refiners for buying Iranian oil have created difficulties receiving crude and led them to sell product under other names, sources familiar with the matter said, evidence of the disruption that Washington's stepped-up pressure is inflicting on Tehran's biggest oil buyer. The targeting of independent refiners, known as teapots, marked an escalation in Washington's efforts to cut off Tehran's export revenue as President Donald Trump seeks to pressure Iran into a deal over its nuclear programme. Washington's sanctions against Shandong Shouguang Luqing Petrochemical in March and Shandong Shengxing Chemical in April have also begun to deter other, larger independent Chinese refiners from buying Iranian crude, three of the sources said.
