Sanctions on Russia will be lifted once Moscow agrees to bring an end to the conflict in Ukraine and no sooner, German Chancellor Angela Merkel said Tuesday.

The German leader said that the removal of sanctions would be economically beneficial to both Russia and Germany but insisted that Moscow would have to cease its imposition on Ukraine before these sanctions could be lifted and the advantages felt.

“Ukraine does not have full sovereignty,” Merkel told reporters Tuesday at her annual summer news conference in Berlin.

Russia has been subject to sanctions from the European Union, the U.S. and several countries since 2014 when it backed pro-Russian and anti-government groups in the Donbass regions of eastern Ukraine, resulting in major conflict and the annexation of the Ukrainian territory of Crimea.
