India has reportedly approached the United States to extend its waiver on Russian oil imports as the Strait of Hormuz continues to see disruptions for 75 days now, straining oil supplies across the world. The US had first cleared the arrangement in March and expanded it later with the current authorisation set to remain valid until May 16. The waiver was introduced to help stabilise oil markets by allowing additional crude supplies. While Russian oil is not under blanket sanctions, Washington has repeatedly urged India to reduce discounted purchases as part of efforts to pressure Moscow over the war in Ukraine, Bloomberg reported.
