MOSCOW, Dec 23 Reuters The Russian rouble weakened in early trade on Friday, cutting short a slight recovery in the previous session as fears over oil and gas sanctions unnerved markets, though it got some support from a monthend tax period.

At 0706 GMT, the rouble was 0.8 weaker against the dollar at 69.74 , slipping back towards its weakest since April 28 of 72.6325, hit in the previous session.

It had lost 0.4 to trade at 73.87 versus the euro and shed 1 against the yuan to 9.87 .

Yuanrouble trading volumes exceeded 15 billion yuan on Thursday, a record on Moscow Exchange. Russia will start buying yuan on the market next year if oil and gas revenues meet expectations, two sources told Reuters, a report that was later confirmed by Finance Minister Anton Siluanov.

Market jitters over the impact of an oil embargo and price cap have seen the rouble plunge in recent days, with weekly losses exceeding 15 at its weakest point on Thursday.

Siluanov said that a recovery in imports, which had collapsed as Western nations imposed harsh sanctions on Moscow over its actions in Ukraine, was also behind the currency39;s slide.

Brent crude oil , a global benchmark for Russia39;s main export, was up 0.9 at 81.7 a barrel.
