India’s largest private port operator, Adani Group, has banned entry of tankers that are sanctioned by the US, UK or the European Union, according to multiple local media outlets.

Adani’s port footprint in India is more focused on containers and dry bulk than tankers with analysts suggesting the news will not severely curtail Russian oil shipments into the world’s most populous nation.

However, the group is aware of the threat from Washington of secondary sanctions. Moreover, the US is asking G7 countries today to level India and China with sharply higher tariffs for buying Russian oil.

The US last month increased tariffs on Indian imports to 50% over the country’s purchases of Russian oil, something that has seen Indian refiners finally reduce their appetite for Russian crude.
