The ongoing debate over the future of Ukraine has exposed a deep rift between the opposing visions of the EU, US and Russia at the Munich Security Conference in Germany.

European Council President Herman Van Rompuy said the “future of Ukraine belongs with the EU” while US Secretary of State John Kerry said the US backed Ukraine’s “fight for democracy”.

Russian Foreign Minister Sergei Lavrov accused those defending violent protests of double standards.

Ukraine has been in turmoil since November, when it scrapped an EU accord in favor of a Russian bailout.

The security conference is an annual event held to discuss military and political affairs.

Herman Van Rompuy’s opening speech referred to the EU’s offer of close association with Ukraine.

“The offer is still there and we know time is on our side. The future of Ukraine belongs with the European Union,” he said.

John Kerry launched a broad attack on “a disturbing trend in too many parts of Central and Eastern Europe and the Balkans”.

He said: “The aspirations of citizens are once again being trampled beneath corrupt, oligarchic interests – interests that use money to stifle political opposition and dissent, to buy politicians and media outlets, and to weaken judicial independence.”

John Kerry added: “Nowhere is the fight for a democratic, European future more important today than in Ukraine. The United States and EU stand with the people of Ukraine in that fight.”

The secretary of state said the “vast majority of Ukrainians want to live freely in a safe and prosperous country – they are fighting for the right to associate with partners who will help them realize their aspirations”.

In an apparent swipe at Moscow, John Kerry added that “their futures do not have to lie with one country alone, and certainly not coerced”.

Sergei Lavrov said that a “choice is being imposed [on Ukraine] and Russia is not going to be engaged in this”.

He asked: “What does incitement of violent street protests have to do with the promotion of democracy? Why do we not hear condemnation of those who seize government buildings and attack police and use racist, anti-Semitic and Nazi slogans?”

Sergei Lavrov said: “Why are many prominent European politicians actually encouraging such actions, although back home they are quick to severely punish any violations of the law?”

Interfax also quoted Sergei Lavrov as saying: “When John Kerry… says that Ukraine should choose who it is with – with the whole world or with one country, Kerry – with his experience, good sense – is the last person I would expect such propaganda from.”

On Saturday John Kerry is scheduled to meet Ukraine opposition leaders said to include Arseniy Yatsenyuk, boxer-turned-politician Vitaly Klitschko, legislator Petro Poroshenko and pop star Ruslana Lyzhychko.

The White House has confirmed it is discussing possible sanctions against Ukraine with the US Congress.

It was unclear whether John Kerry will meet Ukrainian Foreign Minister Leonid Kozhara, who is at the summit.

Before arriving in Munich, John Kerry said that concessions from President Viktor Yanukovych had “not yet reached an adequate level of reform”.

Arseniy Yatsenyuk, who heads the Batkivshchyna party, recently refused an offer from President Viktor Yanukovych to become PM, one of the concessions.

President Viktor Yanukovych, who is currently on sick leave, has also tried to ease the crisis by repealing anti-protest laws, signing an amnesty for protesters and accepting the resignation of his cabinet.

However, opposition leaders are calling for his resignation and early elections.

One key issue for John Kerry and the opposition leaders will be the issue of Ukraine protester Dmytro Bulatov.

Activist Dmytro Bulatov went missing for eight days and said he had been kidnapped and tortured by captors who spoke with Russian accents.

He is now in hospital in Kiev under guard from both police and anti-government demonstrators.

Both White House spokesman Jay Carney and EU foreign affairs chief Catherine Ashton said they were “appalled” by the apparent signs of torture.

US ambassador to Ukraine Geoffrey Pyatt went to the hospital on Saturday to try to meet Dmytro Bulatov.

Ukraine’s interior ministry says it wants to interrogate Dmytro Bulatov on suspicion of organizing mass unrest, and to examine his account of torture.
