At 0708 GMT, the FTSEurofirst 300 index of top European shares was up 0.2 percent at 1,357.98 points.
Shares in Alstom - which is reviewing a bid by U.S. giant General Electric for its energy activities - were up 2.1 percent after German Chancellor Angela Merkel said on Saturday that the German government would support a tie-up between Siemens and Alstom if the companies decided that it made sense.
Miners were also on the rise, climbing along with metal prices, with Rio Tinto up 2.5 percent and BHP Billiton up 1.5 percent.
