It's a nakedly imperial gambit, the Western ruling classes are attempting to deny Middle Eastern oil to Russia and China. Iran is their only capable opposition in the region, every other Gulf country is a bought-and-paid-for satrapy which just cosigned a genocide on its doorstep.

Coals to Newcastle.

I would first assume it’s marginal amount of oil.

My low effort search suggests no significant oil export to russia https://oec.world/en/profile/bilateral-country/irn/partner/r... (2022 data, maybe something changed)
