The UN Security Council is scheduled to vote tonight on a draft resolution imposing new sanctions on North Korea after the United States toned down its demands in a bid to win support from Russia and China. <br/><br/>Washington has led the international drive to punish the rogue state after it detonated its sixth and most powerful nuclear device earlier this month. <br/><br/>The UN had originally pushed for a strict oil embargo, as well as a freeze on the assets of North Korean leader Kim Jong-Un. A new draft text circulated late yesterday maintains an embargo on gas but would limit sales of oil to 500,000 barrels for three months from October 1 and 2 million barrels from January 1 for a period of 12 months. <br/><br/>Britain and France — permanent veto-wielding Security Council members along with the US, China and Russia — have given Washington their strong backing. It remained unclear whether Russia and China would support the new raft of sanctions. <br/><br/>The US Energy Information Administration says, estimates suggest Pyongyang imports about 10,000 barrels of crude oil a day, almost all of it from China.
