BRUSSELS: European Union and Russian leaders will trade recriminations over Ukraine at a summit on Tuesday, as the former Soviet republic reels from violent unrest after spurning the EU's embrace and lurching back towards Moscow.
Russian President Vladimir Putin travels to Brussels for talks with EU leaders at a time when relations are strained over Ukrainian President Viktor Yanukovich's decision in November to turn his back on a trade and political agreement with the EU in favour of closer trade ties with Russia.
That decision, rewarded with a $15 billion bailout from Russia, sparked weeks of pro-EU demonstrations in Kiev which three protesters have been killed.
Police clashed with protesters in the Ukrainian capital again on Sunday and the opposition said it would keep pushing for early elections, despite being offered the prime minister's post by Yanukovich.
The 28-nation EU, which accuses Russia of putting trade pressure on Ukraine and other ex-Soviet states tempted by closer ties with Brussels, showed its anger by cancelling the dinner that traditionally precedes its twice-yearly summits with Russia.
It has opted instead for an intensive two-and-a-half-hour session of talks, restricted to top officials, to permit an in-depth discussion about Ukraine and other divisive issues.
Putin and Foreign Minister Sergei Lavrov will represent Russia while European Commission President Jose Manuel Barroso, European Council President Herman Van Rompuy and EU foreign policy chief Catherine Asthon will speak for the EU.
Russia, which regards Ukraine as part of its sphere of influence, has told European governments to stop meddling in the Ukrainian crisis and has criticised politicians such as Ashton for visiting protest sites in Kiev.
Russia and the EU have had "a number of differences which need to be discussed and clarified" at the summit, Van Rompuy said in a statement.
The EU's strategy of forging closer ties with ex-Soviet states was left in tatters when Armenia opted last September to join a customs union led by Moscow. Ukraine was next to jilt the EU, after Moscow tightened checks on its imports and threatened to cut off its gas supplies.
Van Rompuy and Barroso will stress to Putin that "there shouldn't be any interference or threats" and that Ukraine and other ex-Soviet states should be free to take their own decisions, one EU source said, speaking on condition of anonymity.
