The European Commission killed the deal over concerns of dominance in the derivatives market.

"The merger between Deutsche Boerse and NYSE Euronext would have led to a near-monopoly in European financial derivatives worldwide," Joaquin Almunia, the EU's competition commissioner, said in a statement.

"These markets are at the heart of the financial system, and it is crucial for the whole European economy that they remain competitive. We tried to find a solution, but the remedies offered fell far short of resolving the concerns."

The NYSE said today the two exchange operators are now in talks to kill their agreement, and that it now plans to resume its $550-million (U.S.) share buyback program.

"The significance is that the market was expecting a read of 49.6, indicating contraction in the manufacturing sector," Derek Holt and Dov Zigler said of the number in China.

In the United States, the measure rose to 54.1 from 53.1.

"It's not just China seeing an expansion in factory output in January," said senior economist Krishen Rangasamy of National Bank of Canada.." A now meaner and leaner U.S. manufacturing sector continues to increase output."

"But that number only draws more attention to the diverging economic within the European Community," the Scotia Capital economists said.
