A German refinery partly owned by Moscow has started mixing US oil with Russian crude

The refinery in Germany is mixing US crude with Russian crude, according to sources.

About 20% of what the refinery is processing is US crude. The first delivery of American oil in several years took place at the Baltic coast port of Rostock.

The US crude supplies mark a pivot for the area as it has long relied on Russian crude.

German Economy Minister Robert Habeck said in April that it would need additional support from Poland to get deliveries from other countries.

The EU plans to cut off seaborne imports of Russian oil by the end of the year in response to Russia's invasion of Ukraine.

The EU saw an increase in flows at the start of August due to the embargo.

Cargo ships obscure the origins of crude to allow goods to keep moving, as shipments to European buyers reached a five week high through the first week of this month.
