Vladimir Putin, shut out of a G7 summit over Russia’s role in Ukraine, parried the snub yesterday with a terse message for world leaders who lunched without him in Brussels: “Bon appetit”.

Putin should have been hosting the heads of leading industrialised nations at a summit of the G8 in the Black Sea resort of Sochi this week. But the G7 nations scotched those plans in protest against Russia’s annexation of Ukraine’s Crimea region in March, and the leaders of the US, Britain, France, Germany, Canada, Italy and Japan held their summit without him.

Asked how he felt about this, Putin barely broke stride to spit out an answer to Kremlin reporters who had been advised to await him at the bottom of a sweeping staircase at the Russian Geographical Society after a meeting on Arctic policy.

“I would like to wish them bon appetit,” he said, using the Russian equivalent of the phrase, and then walked away swiftly.

Kremlin’s leader isolation from the West is only partial

Russia joined the G7 in 1997, making it the G8 and marking a milestone in Moscow’s rapprochement with the West after the collapse of communism and break-up of the Soviet Union in 1991. But the crisis in Ukraine has driven Russia’s relations with the US and EU to a post-Cold War low. Western nations have imposed visa bans and asset freezes on officials, lawmakers and companies close to Putin.

At the G7 summit, which ended yesterday, the leaders threatened to impose harder-hitting sanctions on Russia if it did not help restore stability to eastern Ukraine, where Western nations accuse Moscow of supporting separatists.

Putin’s isolation from the West is only partial. From St Petersburg he was flying to France, where he was having supper with President François Hollande later yesterday before taking part in D-Day 70th anniversary commemorations toady. He is expected to hold meetings with German Chancellor Angela Merkel and British PM David Cameron while in France.
