The Security Council will vote later on Tuesday on a resolution drafted by France, Britain and the United States to ban the supply of helicopters to the Syrian government and to blacklist Syrian military commanders, Reuters reported.
"I think it is totally inappropriate," Putin told a news conference in Bishkek, the capital of Kyrgyzstan, after meeting his Kyrgyz counterpart Almazbek Atambayev.
"It would undermine trust in the negotiating process. Russia will not support any new sanctions against the Syrian leadership."
Russia's Deputy U.N. Ambassador, Vladimir Safronkov, told reporters on Friday that Moscow would veto the draft resolution.
