Denmark is considering ways to limit a potentially environmentally harmful shadow fleet of tankers from carrying Russian oil through the Baltic Sea, Danish Foreign Minister Lars Lokke Rasmussen said on June 17. Since Western governments imposed a price cap on Russia's oil to limit funds for its war in Ukraine, Russia has relied on a fleet of aging tankers based outside the West. About one-third of Russia's seaborne oil exports pass through the Danish straits between the Baltic and North seas, and any restrictions on the tankers could send oil prices higher and hit the Kremlin's finances. The Russian Embassy in Copenhagen called any proposed restrictions "unacceptable."
