The U.N. Security Council is set to vote on Tuesday on a bid by Western powers to ban the supply of helicopters to the Syrian government and to blacklist Syrian military commanders over accusations of toxic gas attacks, despite a pledge by Russia to veto the move.
The Security Council showdown - pitting Syrian ally Russia against the United States, France, Britain and others - comes amid U.N.-led peace talks between the warring Syrian parties in Geneva, which began last week.
A resolution needs nine votes in favor and no vetoes by the United States, France, Russia, Britain or China to be adopted.
Russia has vetoed six Security Council resolutions on Syria since the conflict started in 2011. China joined Moscow in vetoing five resolutions. It was unclear how Beijing planned to vote on Tuesday
Britain and France first circulated the draft resolution to the 15-member council in late December in response to the results of an investigation by the U.N. and the Organization for the Prohibition of Chemical Weapons (OPCW).
