Since Vladimir Putin launched his invasion of Ukraine, Russia has been subjected to the heaviest sanctions of any country in the world.

A fossil fuel superpower, Russia is no longer able to export coal to the European Union and will soon lose 90% of its oil sales to the bloc. In the other direction, the EU has banned the export of hundreds of goods to Russia, from hi-tech military kit and semiconductors that could aid Russia’s military, to makeup, handbags and clothes that may turn a handsome profit for Russian entrepreneurs.
