Indian refiners are wary of buying Russia crude oil loading after Dec. 5 when European Union sanctions take effect, pending clarity on the proposed G7 price cap mechanism, according to sources familiar with the refiners’ crude purchase plans. Chinese refiners have already begun slowing down Russian oil imports from next month. Reduced buying by both of them would leave Russia chasing alternative customers, potentially depressing prices even if those new buyers are unlikely to join a plan by rich nations in the Group of Seven (G7) to cap Russian oil prices.
