LONDON, Dec 2 (Reuters) - Brent crude oil steadied below $110 a barrel on Monday after Chinese data showed strong industrial activity and as social and political unrest in Libya limited supply from the key North African producer.
Brent crude prices fell at the end of last week, losing more than $1 a barrel on signs of over-supply in international markets and worries over global economic growth.
But the official Purchasing Managers' Index on Monday showed manufacturing growth in China, the world's biggest crude oil importer, at an 18-month high in November due to robust domestic and foreign demand.
Brent crude for January was unchanged at $109.69 a barrel by 1215 GMT, after finishing down $1.17 in the previous session. U.S. crude was up 10 cents at $92.82 a barrel, after settling 42 cents higher on Friday.
"We are back around $110 after better-than expected Chinese factory data," said Carsten Fritsch, senior oil and commodities analyst at Commerzbank in Frankfurt.
Oil exports from Libya are only around 130,000 barrels per day (bpd), Deputy Oil Minister Omar Shakmak told Reuters in an interview on Monday, more than 1.2 million bpd below pre-revolution supply levels.
"OPEC oil supply is also down a bit due to lost Libyan exports, keeping the market balanced," Fritsch said.
Oil prices found some extra support from evidence that the Organization of the Petroleum Exporting Countries (OPEC) pumped less oil in November, mainly due to Libya.
Reuters' monthly OPEC survey on Friday showed the cartel produced 29.64 million bpd in November, a two-and-a-half-year low and down from a revised 29.70 million bpd in October.
The Reuters' survey estimated protests at Libyan oilfields and terminals cut average output to 350,000 bpd in November and by the end of the month production was around 250,000 bpd, a fraction of the 1.4 million bpd it pumped earlier this year.
In recent weeks Libyan supply has fallen even further, Deputy Oil Minister Shakmak told Reuters, with total oil output down to just 224,000 bpd.
OPEC ministers are meeting in Vienna on Wednesday to decide production policy, and ministers and OPEC officials have indicated the group's output target is likely to stay unchanged at 30 million bpd.
But next year production will need to be reduced as demand for OPEC oil will decline sharply, analysts say.
"From now until the end of March, the market looks well balanced and the price should stay supported. But from June, there will be a need for a cut," a senior OPEC delegate told Reuters.
