"As for Russia’s participation in the G7 meetings, in 2014 Russia was expelled for certain reasons, and the Russian president recently visited France. There may be slight advances in the implementation of the Minsk process but if we really move forward, it would create a new situation," Merkel told reporters ahead of the meeting with UK Prime Minister Boris Johnson.
She added that "as of today, we have not advanced so far that I can say that the reasons stated in 2014 have been eliminated."
The Minsk agreement was signed in February 2015 by the leaders of Ukraine, Russia, France and Germany to ensure a ceasefire in eastern Ukraine.
On Tuesday, US President Donald Trump reportedly agreed with French President Emmanuel Macron, who said that he would support Russia's return to the G7 group and subsequent resumption of the G8 format.
