Russian President Vladimir Putin fired off against Turkey on Thursday, ruling out any reconciliation with its leaders and accusing Ankara of shooting down a Russian warplane to impress the United States, dismissing the possibility that the downing of the warplane over the Turkish-Syrian border last month was an accident, calling it a "hostile act".

"We find it difficult if not impossible to come to an agreement with the current leadership of Turkey," the Kremlin strongman said at his annual news conference.

On Thursday, Putin went as far as to say that the so-called 'Islamic State of Iraq and the Levant' (ISIL) takfiri group was a "secondary issue" in Syria as it was created as "cannon fodder under Islamist slogans" to protect economic interests of other players, although he did not name Turkey.

On the economic level, Putin said Russia was prepared to face any economic situation as the country's energy-dependent economy reels from lower oil prices.

"The government, of course, is preparing scenarios for any development of the situation," Putin said at his annual press conference in Moscow.

Despite a downward trend in oil prices, the Russian government will not rush to adjust its budget, Putin said.

"Volatility [in oil prices] is very high," Putin said "We will not hurry to recalculate and make adjustments to the budget because it entails a reduction in funding and in the social sphere and the real sector."

Putin said last December that Russia's economic woes "under the most unfavorable world conditions" would last two years.

He also noted that Russia was not planning to impose sanctions against Ukraine after Moscow slashed its free trade agreement with Kiev as it is set to enter a similar deal with Brussels.

"We are not planning to impose any kind of sanctions against Ukraine," Putin said at his annual press conference attended by nearly 1,400 Russian and foreign journalists.

"Ukraine cannot be placed in conditions worse than those of our external partners, but of course, Ukraine will have no benefits or trade preferences with Russia from January 1, 2016."

Moreover, Russian President threw his support behind a US-backed measure at the UN Security Council to ramp up sanctions against the ISIL takfiri group and cut off its revenue flows.

"We support an initiative by the United States including on the preparation of a UN Security Council resolution on Syria," Putin told reporters during an annual news conference.

It calls on governments to ensure they have adopted laws that make the financing of ISIL and of foreign fighters who join its ranks a serious criminal offense.

The measure urges countries to "move vigorously and decisively to cut the flow of funds, and other financial assets and economic resources" including oil and antiquities to the ISIL group, and to "more actively" submit names to the sanctions list.

UN Secretary-General Ban Ki-moon will be asked to prepare a sweeping report in 45 days on the IS threat and its revenue streams.

"If we can get at ISIL's wallet and its financial coffers in an intensified and even more aggressive way, that's going to have a material effect on their ability to prosecute war," US Ambassador Samantha Power said.
