The national statistics agency, Insee, said that France's gross domestic product rose 0.5 percent in the second quarter, largely on a rebound in exports, domestic household demand and public spending. The figure was well above the consensus forecast of 0.1 percent and even the more optimistic Banque de France prediction of 0.2 percent growth.
But the positive figure wasn't a total surprise. Finance Minister Pierre Moscovici said this weekend that the economy was out of recession, even before the official data became known.
Insee says the April-to-June growth was the strongest quarterly growth since early 2011, when Europe's debt crisis exploded, forcing governments to cut spending and dragging many economies into recession.
France, Europe's second-largest economy, has fared better than many, but its growth has been stagnant for two years. GDP shrank 0.2 percent for each of the last two quarters.
That would mean that the second half of 2013 will not keep pace with the second quarter's growth. Wednesday's figure is also just a first estimate and could later be revised.
