U.S. President Donald Trump's demand on India to halt Russian oil imports could threaten billions in Russian revenues, prompt Moscow to retaliate by stopping a major U.S.-led oil pipeline and potentially lead to a new global supply crisis.

The Indian government had “not given any direction to oil companies” to cut back imports from Russia, said one senior official.

President Trump says India buys military equipment and oil from Russia, which enables Moscow’s war in Ukraine.
