India's Adani bans entry of sanctioned ships at its ports, sources say

India's largest private port operator, Adani Group, has banned entry of tankers that are sanctioned by Western countries at all of its ports, three sources said and documents show, a move that could hit Russian oil supplies for two Indian refiners. Adani did not immediately respond to Reuters requests for comment. India is the biggest buyer of Russian seaborne oil, mostly shipped on tankers that are sanctioned by the European Union, the United States and Britain.
