LONDON, Nov 30 (Reuters) - European shares fell in early trading on Monday, led lower by oil producers and financial stocks, as concerns about the Dubai debt crisis weighed.

By 0823 GMT, the pan-European FTSEurofirst 300 index of top shares was down 0.7 percent at 993.76 points after rising 1.2 percent on Friday.

Energy stocks featured among the worst performers. BG Group (BG.L: Quote, Profile, Research), BP (BP.L: Quote, Profile, Research) and Royal Dutch Shell (RDSa.L: Quote, Profile, Research) were down 0.5 to 0.7 percent. Banks were also lower, with Societe Generale (SOGN.PA: Quote, Profile, Research), Lloyds Banking Group (LLOY.L: Quote, Profile, Research) and Barclays (BARC.L: Quote, Profile, Research) falling 0.8 to 1.4 percent.

The United Arab Emirates offered banks emergency support on Sunday, the first steps to ease fears that a looming debt default by two of Dubai's flagship firms could derail the global economic recovery.

But the move to inject liquidity into Dubai's banks by the central bank of the Gulf Arab state, together with promises by neighbouring city-state Abu Dhabi to provide selective support to Dubai companies was seen as by analysts as the bare minimum. [ID:nGEE5AS0AH]

Some analysts said the situation might improve in the coming days.

"The general sentiment around the Dubai debt crisis is that it will be contained," said Bernard McAlinden, market strategist at NCB Stockbrokers. (Reporting by Joanne Frearson) ((joanne.frearson@thomsonreuters.com; +44 207 542 2773, Reuters Messaging:joanne.frearson.thomsonreuters.com@reuters.net))
