At some point the West's warnings will have to become deeds, part of the problem is they don't know which Putin they're dealing with.
Rugged Russian President Vladmir Putin visited a centre for endangered Persian leopards at Sochi National Park.
These are difficult days for Ukraine, a country edging toward its second revolution in a decade.
Vladimir Putin has said Russia could reconsider the participation of Western companies in its economy, including energy projects, if sanctions continued.

We would very much wish not to resort to any measures in response.
But if something like that continues, we will of course have to think about who is working in the key sectors of the Russian economy, including the energy sector, and how.
The United States on Monday announced a new round of sanctions aimed at business leaders and companies close to Putin, while the European Union followed up on Tuesday by naming 15 Russians and Ukrainians to its blacklist, moving to freeze assets and deny visas.
Once one of the most prominent European leaders, Germany's former Chancellor Gerhard Schroeder, is facing heavy criticism after photographs showing the retired leader in a warm embrace with Russian President Vladimir Putin emerged.
The German government and media distanced themselves from the ex Chancellor.
Der Spiegel, a national magazine, published the photographs along with a commentary that said: "Schroeder celebrates his birthday with Putin and makes Germany's foreign policy look absurd."
Mr Schroeder's office had no comment on the pictures, which according to the media reports were taken on Monday evening outside the Yusupov Palace in St. Petersburg where he was attending a belated celebration of his 70th birthday.
Russian President Vladimir Putin has derided the internet as a Central Intelligence Agency project and has pledged to protect Russia's interests online.
According to the Associated Press, Putin mocked the World Wide Web at a media forum in St. Petersburg, claiming that it was "originally a CIA project" and is "still developing as such".
The Kremlin has long sought greater controls over the internet as many opposition activists, who are banned from state media, use the medium to promote their views and organise protests.
President Putin says Russia will award state medals to some Russian servicemen who are involved in the Crimea operation.
Speaking to Russian television Putin said that there was nothing to prevent the normalisation of relations between Russia and the west, but that it would depend on the west.
The much-vaunted 'reset' in relations between the US and Russia was already over before the crisis in Ukraine, Vladimir Putin has said.
The Russian President said the conflict in Libya had already soured relations between the two powers but he insisted Russia would do "everything possible" to restore trust.
Russia's annexation of Crimea was partly influenced by Nato enlargement in the Black Sea region, Vladimir Putin has said.
The Russian President said the decision to beef up Nato's presence in eastern Europe had meant Russia was "forced to respond".
Vladimir Putin has expressed disbelief that areas of eastern Ukraine were ever ceded from Russia.
Mr Putin said Russian-speaking cities such as Donetsk and Kharkiv were historically part of 'Novorossiya' [New Russia] during the Tsarist era and "God knows" why they became part of Ukraine.
The area in question was transferred to Ukraine during the Soviet era.
Vladimir Putin has denied any Russian involvement in the unrest in eastern Ukraine.
Speaking during a televised phone-in on Russian television, the President said there were "no special forces, no instructors" from Russia in eastern Ukraine and that those taking up arms were "all local people".
He also called for "dialogue" between pro-Russian elements in the east of the country and the authorities in Kiev.
Mr Putin also struck a conciliatory tone, saying that Russia and Ukraine "share an enormous number of interests and if we want to be successful we must work together".
President Vladimir Putin has said Russia expects a "clear condemnation" from the international community and the United Nations over "Kiev's anti-constitutional action in eastern Ukraine," RIA Novosti reported.
Nick Clegg and Nigel Farage have clashed over British foreign policy regarding Ukraine, Russia and Syria.

Mr Farage also attempted to clarify comments he made about Russian president Vladimir Putin, saying he admired him "as an operator" but not as a man.
