* U.S. crude stocks fall by 5.5 million barrels -EIA
* China's industrial profits grow at fastest in 8 months
* Russia says OPEC+ may consider ending oil output cuts in 2020 (Updates prices, adds commentary)
HOUSTON, Dec 27 (Reuters) - Oil prices rose on Friday to three-month highs after data showed U.S. crude inventories declined much more than expected and upbeat economic data and optimism over a U.S.-China trade deal improved investor sentiment.
Brent crude was up 31 cents at $68.23 a barrel at 10:47 a.m. CST (1647 GMT). West Texas Intermediate was up 13 cents at $61.81 a barrel.
U.S. crude stocks fell by 5.5 million barrels in the week to Dec. 20 to 441.4 million barrels, the Energy Information Administration said on Friday. The inventory decline far exceeded the 1.7-million-barrel drop expected by analysts in a Reuters poll.
"Inventories are bullish almost across the board," said Josh Graves, senior market strategist at RJO Futures in Chicago, adding a year-end jump in stock prices has helped lift oil prices as consumer sentiment improved this month.
"It's a Santa Claus rally. People tend to buy more things that will indirectly drive the price of oil up," Graves said.
Oil trade was thin. But upbeat economic data from China and the United States and optimism over a trade deal between the two major economies improved investor sentiment.
In the United States, a survey on Thursday showed online holiday purchases by U.S. consumers reached a record, beating analysts' expectations and lifting U.S. stocks to fresh highs.
Profits at China's industrial firms rose at the fastest pace in eight months in November, data from the National Bureau of Statistics showed.
China and the United States cooled their 17-month long trade war earlier this month, announcing a Phase 1 agreement that would reduce some U.S. tariffs in exchange for more Chinese purchases of American farm products.
Brent has jumped more than a quarter in 2019, while WTI is up around 35%, bolstered by the group's output cuts.
OPEC+ this month decided to prolong an oil output restriction deal until the end of March and to deepen the cuts in order to balance out the oil market.
The Organization of the Petroleum Exporting Countries and its allies including Russia, known as OPEC+, may consider wrapping up their oil output reduction in 2020, Russian Energy Minister Alexander Novak said on Friday.
"Novak's comments changed the outlook a little bit. But the market has to remember that Russia always talks down the cuts. It's their way of negotiating with OPEC," said Phil Flynn, an analyst at Price Futures Group in Chicago.
