French President Francois Hollande said the meeting held yesterday sent a clear signal of unity by urging Russia to help stabilise the situation in Ukraine, while keeping the threat of further sanctions on the table.
In faraway Moscow, Putin seemed to shrug off the snub of having not been invited to Brussels, but declared he was still open to "dialogue."
They also nixed Putin's plan to hold the meeting in Sochi, the city Russia lavished billions on to host the 2014 Winter Olympics.
Around the dinner table in Brussels, "there were seven of us, not eight," Hollande said afterward.

In a joint statement, the leaders of the US, Canada, Japan, Britain, France, Germany and Italy urged Russia to recognise the results of Ukraine's recent presidential poll, complete the withdrawal of its troops on the border with Ukraine and stop the flow of weapons and militants.
But the tough language couldn't hide the fact that many US allies, especially the Europeans, have shifted their focus toward re-engaging with Putin since Russia has refrained from a full-blown invasion of Ukraine and started pulling back its troops.
Hollande, British Prime Minister David Cameron and Merkel are all planning to hold talks with the Russian president in France during ceremonies marking the 70th anniversary of the D-Day invasion this week.
Obama, however, has no plans to meet with Putin - a clear indication the US is more reluctant than its European peers about renewing the dialogue.
