Russia's asset seizures limit exit options for Western companies.

Russia has taken temporary control of assets belonging to Finnish energy group Fortum and its former German subsidiary Uniper, raising concerns over the fate of other Western companies in Russia. The move comes as pressure grows to impose more sanctions on Moscow over Ukraine. Both companies have been trying to exit Russia, and the decree outlining possible retaliation if Russian assets abroad are seized shows Moscow has already taken action against Uniper's Russian division Unipro and Fortum's assets.
