U.S. Targets Oligarchs’ Hidden Assets, Russian Military Supply Lines

LONDON—The U.S. government and its allies plan to sanction institutions and individuals who help Russian oligarchs hide their assets, while governments are also working on new measures intended to disrupt supply chains necessary to provide Russia with “the tools of war,” Deputy Treasury Secretary Wally Adeyemo said Tuesday.

In response to Russia’s invasion of Ukraine, the U.S., the European Union, the U.K., Australia and others have said they are moving to scrutinize the assets of a handful of rich and powerful Russians. Western governments say these oligarchs have profited from close ties to Russian President Vladimir Putin. Many have spent lavishly outside Russia, boosting local economies with property purchases and other investments.
