The U.S. President Barack Obama, the German Chancellor Angela Merkel and the U.K. Prime Minister David Cameron are expected to have discussions with the Russian President in a bid to resolve the crisis in Ukraine. At the same time, the U.S. Secretary of State John Kerry also holds talks with Russian Foreign Minister Sergei Lavrov in Paris. Last night the Group of Seven leaders spared Russia more sanctions over Ukraine, while urging it to complete the pullback of its troops from the country’s border. G-7 leaders warned Russia against using energy to force compliance with its political goals. On its part, Russia is “very worried” about the Ukrainian offensive, Foreign Ministry spokesman Alexander Lukashevich said at a briefing in Moscow. „I’ll talk with all of them,” Putin said to the media, referring to the political leaders . But he was not revealing his position and the commentators anticipated that it is difficult to make Russia to step back.
