Singapore: Oil futures fell around 2 percent in Asian trade on Wednesday after Saudi Arabia's oil minister Ali Al Nuaimi appeared to rule out a cut in crude production, just days before the oil producers' meet, which is scheduled to take place in Doha on Sunday.
As of 0638 GMT, Brent crude dropped 85 cents to $43.84 a barrel, or 1.9 percent, after hitting a four-month high in the previous session, when it settled up $1.86, or 4.3 percent.
U.S. crude dropped 87 cents, or 2.06 percent, to $41.30 a barrel after gaining $1.81, or 4.48 percent, the day before.
A firmer U.S. dollar, which makes dollar-denominated commodities more expensive for holders of other currencies, also pressured prices.
Comments by oil minister Ali Al Nuaimi in the Saudi-owned al-Hayat newspaper, published on Wednesday, appeared to contradict Tuesday's reports that Russia and Saudi Arabia had reached consensus on an oil output cap for the April 17 meeting.
"Forget about this topic," Al Nuaimi told the paper, when asked about any possible reduction in his country's production.
Investors are wary of the outcome of this meeting that may lead to an oil output freeze.
"Investors have been burned before that Opec (the Organistion of the Petroleum Exporting Countries) will do something — the fundamentals of this thought have shown to be made of sand," said Ben Le Brun, market analyst at Sydney's OptionsExpress.
Oil prices had been under pressure earlier in the session as profit-taking and concern over a larger-than-expected build in U.S. crude stocks outweighed news of the Russia-Saudi deal.
"There are two things. There has been a fantastic rise in prices so I think in the Asian time zone there's been a little bit of profit-taking," said Jonathan Barratt, chief investment officer at Sydney's Ayers Alliance.
"The second thing is that while we are waiting for more official inventory data, investors are thinking: 'Are prices warranted at these levels?'," he said.
U.S. crude stocks rose by a larger-than-expected 6.2 million barrels to 536.3 million last week, data from industry group the American Petroleum Institute showed late Tuesday.
That compared with analyst expectations for a 1.9 million barrel increase.
Official inventory data from the Energy Information Administration (EIA) is due later on Wednesday.
Some signs of improving crude demand have appeared as China's crude imports, buoyed by strong demand from independent refiners and better refining margins, rose 13.4 percent in the first quarter from a year ago, customs data showed on Wednesday.
Global oil demand will grow by 1.16 million barrels per day this year, a 10,000-barrel rise compared with earlier estimates, the EIA said in its monthly forecast on Tuesday.
The agency raised its oil demand growth estimate for 2017 by 120,000 bpd to 1.33 million bpd.
